Rear tires on a Kawasaki Z800 take the full brunt of the 800cc inline-four’s power, and a bad choice means spinning up where you need traction most. This guide cuts through the brand noise to find the Z800 rear tire that truly delivers on grip, mileage, and real-world feel.
I’m Mo Maruf — the founder and writer behind GoCarLife. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
If you want a sport-touring radial that balances cornering stick with mileage, or a hypersport tire that prioritizes grip above all else, the options break down by riding style, rubber compound, and load capacity — all wrapped in the search for the best z800 rear tire for your street and canyon riding.
Our Picks at a Glance
How To Choose The Best Z800 Rear Tire
A Z800 rear tire must fit the stock 180/55-17 rim size, but the rubber compound, tread pattern, and construction type decide how the bike actually feels from your first commute to the last canyon run of the season. Knowing what each spec means keeps you from overspending on a track compound that wears out in 3,000 miles, or undershooting on a budget tire that squirms at 80 mph.
Understand the Rubber Compound and Dual-Compound Tech
A single-compound tire uses one rubber mix across the entire tread. It tends to wear evenly but may sacrifice sticky edge grip for center mileage. Dual-compound (or multi-compound) tires place a harder rubber strip in the center for straight-line wear and a softer compound on the shoulders for cornering grip. Bridgestone’s S22 uses front and rear compound tuning for dry grip, while Michelin’s 2CT+ layers two compounds on the tread to extend life without giving up lean-angle confidence. If your Z800 spends most of its time on highways, a dual-compound sport-touring tire stretches the miles between changes.
Check the Load Index and Speed Rating
The load index tells you how much weight the tire can carry at maximum pressure. A load index of 73 (805 pounds) is standard for 180/55-17 rear tires — the MICHELIN Road 5, Kenda KM1, Pirelli Angel GT, and most others on this list carry that rating. The MICHELIN Road 5 goes up to 890 pounds (load index 73 with a higher load range). Speed rating is written as a letter on the sidewall: “W” means the tire is certified up to 168 mph, while “ZR” covers speeds above 149 mph. The Z800 is fast enough to need a W-rating for safe highway cruising and occasional top-speed runs.
Wet-Weather Features: Siping and Silica
Patented XST Evo sipes (tiny slits in the tread blocks) on the MICHELIN Road 5 improve water evacuation so the tire stops as short after 3,500 miles as a new Pilot Road 4. Silica-enriched compounds, found in the Bridgestone S22 and the Kenda KM1, give the rubber better grip on rain-slick asphalt without making the tread wear out faster. If you ride through wet seasons, look for a tire that specifically mentions siping count or silica content — it is the difference between a sketchy ride home and a predictable one.

In-Depth Reviews
1. MICHELIN Road 5 Touring Radial Tire-180/55ZR-17 73W
Our pick — over 4.5★ from 550+ verified ratings; the strongest balance of quality and price.
The rain specialist that still delivers sportbike feel after thousands of miles.
The Road 5 is the tire that made wet-weather confidence a headline feature instead of an afterthought. Michelin’s patented XST Evo sipes (microscopic slits in the tread that pump water away) keep the rubber in contact with asphalt even through standing water. The result is a tire that buyers report “stops as short as new MICHELIN Pilot Road 4 tires” even after logging 3,500 miles — a claim backed by internal wet-lap tests at Michelin’s Ladoux track against competitors from Metzeler, Dunlop, Continental, and Pirelli.
Dual-compound 2CT+ construction places a harder center strip for straight-line wear and softer shoulders for edge grip, so the Road 5 works as well on a highway commute as it does scraping a knee in a canyon. The crowd favorite is the traction — owners praise it at a rate of 31 mentions — and the quality is the most-discussed aspect overall, with 56 people calling it out. The downside? Longevity earns a “mixed” tag in 18 mentions; some owners say it wears faster than they hoped under heavy throttle, though buyers do report the center “takes a while before it starts to flatten out.” At 890 pounds of load capacity, it handles the Z800’s weight with a significant margin over the standard 805-pound rating of most rivals.
The ACT+ casing technology improves dry stability over the Pilot Road 4, meaning you get the turn-in response of a sport tire with the wet-road security of a dedicated touring tire. If you ride year-round or face unpredictable skies, this is the single most trustworthy rear tire on the list — and the unanimous favorite of the 589 people who rated it to 4.9 stars.
What owners rave about
- Superior wet grip — the XST Evo sipes keep traction predictable in heavy rain
- Heats up quickly, even from cold starts, for immediate cornering confidence
- Dual-compound center resists flat-spotting on long highway stretches
What to keep in mind
- Some owners mention the center tread wears faster than expected under aggressive acceleration
- Less ultimate peak grip than a dedicated hypersport tire like the Diablo Rosso III
The Z800 wet-weather winner: MICHELIN Road 5 is the rear tire to buy if you ride through rain seasons, prioritize predictable traction, and want a tire that balances 2,500 miles of twisty-road fun with 3,000 miles of straight interstate.
Trade-off to know: Riders who hammer the throttle from every stoplight may wear the center compound fast — consider the harder-riding Angel GT if mileage is your #1 goal.
2. Bridgestone Battlax Hypersport S22 Motorcycle Tire
The tires that feel like glue on cold asphalt and only get better in the wet.
The S22 is Bridgestone’s premier street sport tire, and it earned that position by focusing on two things riders actually feel: dry grip and wet performance. The rear compound uses fine-grain silica to improve wet traction, while the front and rear pattern design increases pattern rigidity for sharper turn-in response. Owners describe the S22 as “stickier than Pirelli Rosso’s” and report confident grip even at 160-plus mph speeds — proof of how well the compound holds up under the Z800’s power band.
At 9.7 pounds, the S22 is the lightest tire on this list, which reduces unsprung weight and lets the suspension react faster to bumps. The trade-off is load capacity — 600 pounds is lower than the 805-pound standard, though still well within the Z800’s rear-wheel weight envelope for solo riding. The quality and grip each draw heavy praise (41 and 30 mentions respectively). Durability earns a mixed note in 12 comments, with some owners reporting the front side tread wears out quickly. For the Z800, the S22 is a top-tier pick for riders who want an immediate, razor-sharp feel on canyon roads and are willing to replace the rear every 4,000 to 5,000 miles for that sticky edge.
Standout strengths
- Exceptional wet grip — the silica blend provides confidence in rainy conditions that most hypersport tires lack
- Warms up quickly in cold weather — owners say 50°F feel no different than a summer track day
- Superb handling response, especially on twisty backroads and during aggressive corner entry
A few cautions
- Durability is mixed — some customers note the front side tread wears quickly
- Load capacity at 600 pounds is lower than most 180/55-17 rivals; fine for solo riding, less ideal for heavy two-up touring
For the aggressive canyon rider: The S22 delivers the best cold-grip-to-rain-grip balance in the hypersport category, making it perfect for a Z800 that sees weekend twisty-road attacks and the occasional wet commute.
Note on mileage: If you rack up 10,000+ miles a year, the Pirelli Angel GT will outlast the S22 by a significant margin — this tire is built for feel, not distance.
3. Michelin Pilot Power 2CT Motorcycle Tire Hp/Track Rear 180/55-17 73W
MotoGP-derived dual-compound tech you can ride to the track and straight onto it.
The Pilot Power 2CT is the tire Michelin developed from 15 consecutive Grand Prix World Championships, and it shows in the compound layering. The edges of the tread carry a 20-percent softer rubber mix than the center, which means you can lean the Z800 to 51.2 degrees (as measured on Michelin’s test track) and feel the shoulder rubber bite rather than slide. Owners call it “tough to top for the street” and report 7,000 miles from a rear tire on bikes like the ZRX1200R and Z1000 — strong mileage for a tire this sticky.
The trade-off is that this is not a wet-weather specialist. The soft shoulder compound provides phenomenal dry cornering grip, but the tire lacks the deep siping of the Road 5, so riders who see heavy rain regularly should look at the Pirelli Angel GT or the MICHELIN Road 5 instead. Traction and value for money lead the mentions (22 and 23 respectively), and owners consistently praise the ride quality — one rider on a Bandit 1200S said the tire was “comfortable at high speeds in twisties.” Load capacity sits at 805 pounds, matching the Z800’s stock requirements perfectly. If you do track days or carve canyons most weekends and only need the bike to get you there, the Pilot Power 2CT is your tire.
The edge it’s built for: 2CT dual-compound delivers a hard-wearing center strip and a soft outer layer that corners like a track slick — but keep an eye on the center, as owners note it can wear quickly if you do a lot of straight-line highway riding.
Who this suits: Riders who live in dry climates and want a tire that will handle the occasional track session without needing a dedicated set of slicks. The Pilot Power 2CT earns its place with a 4.8-star average across 256 reviews for good reason.
skip it if: Your commute frequently runs through rain — the Road 5’s siped tread is noticeably safer on slick asphalt.
4. Pirelli Diablo Rosso III 180/55ZR17 73W Rear Motorcycle Tire
The tire that turns every corner into an invitation to push harder.
The Diablo Rosso III uses Pirelli’s World Superbike-derived bi-compound technology, placing a wide soft stripe on the side that activates grip starting from mid-lean angle. The result is a tire that feels planted even when you’re deep into a corner, and reviewers point out it makes mid-size bikes like the Honda CB300R and Yamaha R6 feel “like a cornering beast” once the rubber is warm. Pirelli includes a keychain with the tire — a small touch, but one that shows the brand’s racing heritage.
Wet performance is rated as exceptional in the product description, though some owners note the Rosso III feels more skittish on gravel or dirt patches compared to Michelin Pilot Power 2CT tires. The 6-ply construction adds durability, and the 805-pound load capacity is standard for the size. Traction and value for money are the most-praised aspects (32 and 31 mentions), while appearance earns 11 mentions — riders clearly appreciate the aggressive tread pattern. The rear wears fast on high-power bikes, with one owner going through “2 per season” on a CBR929RR. For Z800 owners who prioritize cornering excitement over mileage, the Rosso III delivers an class-leading feeling of connection to the road.
What makes it special
- Bi-compound side soft stripe provides progressive grip from mid-lean to full edge
- 6-ply construction resists cuts and punctures better than standard 4-ply tires
- Owners consistently praise the “sticky” feel once warm — one says they “feel glued to the road”
Limitations to know
- Rear tire wears fast on powerful bikes — expect roughly two per season with aggressive riding
- Less composed on gravel or dirt patches mid-turn compared to Michelin’s 2CT tire
Best for the corner-carver: If your Z800 sees more twisty backroads than straight highways, the Rosso III’s bi-compound turns every entry into a confident, smooth arc.
Reality check: On a Z800, the rear will likely need replacing every 4,000-5,000 miles under hard throttle. Budget for that wear if you choose this tire.
5. Pirelli Angel GT Rear Motorcycle Tire 180/55ZR-17 (73W)
The sport-touring tire that treats long miles like they are not even there.
Pirelli designed the Angel GT with Extended Mileage Sport compound — a rubber formulation that prioritizes low wear without sacrificing wet grip. The tread grooves are arranged for excellent water drainage, and shoppers say it returns the FJR’s handling to neutral and stays comfortable on long-distance tours. The “W” speed rating (168+ mph) means the tire is not just about slow, steady highway miles; it can handle a spirited run when the road opens up. At 6.49 kg (approximately 14.3 pounds), it is mid-weight compared to the Bridgestone S22’s 9.7 pounds and the Kenda KM1’s 17.7 pounds.
Durability is the most-discussed positive aspect, with 11 mentions, alongside value for money. Some owners note it does not offer the same cornering confidence as cheaper tires — a perspective that likely comes from riders comparing it to the stickier Diablo line. That is the trade-off: the Angel GT trades ultimate edge grip for tread life. If your Z800 is used for multi-state touring, weekday commutes, and the occasional weekend blast, this tire will stretch your dollars much further than a hypersport compound. The 805-pound load capacity handles two-up touring without breaking a sweat.
Why it stands out
- EMS compound delivers top-tier mileage for a sport tire — expect 8,000+ miles from the rear
- Excellent water drainage keeps the bike stable in standing rain
- Buyers report neutral handling on heavy sport-touring bikes like the FJR
One honest note
- Cornering grip is less confidence-inspiring than stickier tires like the Diablo Rosso III or the S22 — not a tire for aggressive lean angles
If you measure tire life in years, not months: The Angel GT is the rear tire for Z800 commuters and long-distance riders who put 10,000+ miles on the clock annually and do not need to drag a knee.
Who might pass: Canyon riders who prioritize edge grip will find the Angel GT’s limits too soon — the Rosso III or the S22 offer more cornering confidence at the expense of mileage.
6. Kenda KM1 180/55ZR17 Sport Touring Motorcycle Tire 73W (180/55-17)
The most popular budget-friendly tire on the list — and it legitimately delivers.
With 915 ratings and a 4.7-star average, the Kenda KM1 (this specific SKU with the 4-ply construction) is the crowd favorite for riders who want strong all-around performance without spending premium-tier cash. The advanced rubber compound heats up quickly from cold, and owners mention the rear lasts roughly 8,000 miles (half tread at 4,000 miles) — which is excellent for a tire in this price bracket. The tune apex geometry balances high-speed stability and agile turn-in, making the KM1 feel more like a premium sport-touring tire than its price suggests.
Quality and value for money are the top aspects by a wide margin (69 and 68 mentions respectively). Grip, durability, balance, and handling all earn positive scores (36, 26, 17, and 16 mentions respectively). The KM1 is nearly 8,000 miles for a rear tire, and owners say it offers “excellent grip, stability, and traction in wet/dry.” The downside: some owners note very stiff sidewalls that make mounting a challenge — one needed 40 PSI to seat the beads. A few also report the tire tracks grooves on the highway and produces a slight weave at high speed. At 17.7 pounds, it is noticeably heavier than the Bridgestone S22’s 9.7 pounds — but the higher mass contributes to stability on rough pavement.
What wins riders over
- Value for money is the second most-mentioned aspect (68 mentions) — it delivers sport-touring performance at a fraction of premium-brand prices
- Longevity is a strong point — customers note the rear lasts ~8,000 miles with mixed riding
- tune apex geometry provides stable high-speed feel and responsive cornering for a budget radial
Realities to know
- Stiff sidewalls make mounting tricky — a tire machine or a shop’s help is strongly recommended
- Some reviewers point out slight weave over grooved pavement at highway speeds
- At 17.7 pounds, it is the heaviest tire on this list, which can slightly dull turn-in feel
The budget pick that punches above its weight: The Kenda KM1 (B09QXJRVT2) is the best value-for-money Z800 rear tire for riders who need long tread life and solid all-weather grip without spending Road 5 money. It has more reviews than the top pick — 915 to 589 — but the MICHELIN Road 5 holds a slightly higher score at 4.9 stars.
Who should think twice: If you are a very aggressive rider who prioritizes the last 10 percent of cornering grip, the KM1 may feel slightly vague compared to the S22 or the Diablo Rosso III.
7. Continental ContiSportAttack 2 Front & Rear Tire Set 120/70-17 & 180/55-17
Grip that arrives the moment you start rolling — no warm-up lap needed.
Shoppers say the tire is “super grippy” straight from the start, and one said it felt like “a huge improvement over old Pirelli Diablos” immediately after mounting. The Continuous Compound Technology keeps the rubber’s consistency consistent across lean angles, so the tire does not lose grip as you lean deeper into a turn. It is sold as a front-and-rear set, which makes it convenient for a full tire refresh on the Z800.
Quality and grip are the top aspects (9 and 6 mentions), and owners consistently describe it as their “favorite tire for street/canyon riding.” The load capacity is 805 pounds with a load index of 73, matching the Z800’s stock requirements. Some riders note the tire feels “overwhelmed at full track pace” — it is a stellar street tire that can handle an 80-90 percent track pace, but it is not a dedicated track slick. The set comes with a keychain, a nice touch from Continental. For Z800 owners who want immediate grip for aggressive canyon riding without waiting for tire warmers, the ContiSportAttack 2 is a top-tier pick.
Instant heat, instant grip: The Black Chili compound makes this the quickest-warming tire on the list. If your ride to the twisties is five minutes of highway, the ContiSportAttack 2 is ready before you are.
Who this is for: Riders who start their ride from a cold garage and hit the canyons within a few miles — the ContiSportAttack 2 delivers full grip almost immediately, unlike some hypersport radials that need a mile of aggressive cornering to warm up.
Who should skip: The set is a good value, but if you only need a rear tire and already have a compatible front, the stand-alone options (Road 5, KM1) are more economical.
8. Dunlop Sportmax GPR-300 Sport Front And Rear Motorcycle Tire Set
A front-and-rear set that outlasts premium brands at a fraction of the cost.
The Sportmax GPR-300 is Dunlop’s well-balanced sport radial for street riding. The set includes a 120/70ZR17 front tire and the 180/55ZR17 rear, so it is a complete replacement package for the Z800. The Joint less Band (JLB) rear tire construction uses a continuously wound belt to create a smooth, consistent contact patch — this translates to fewer vibrations and more predictable feedback when you lean the bike. Owners gush about the longevity, with one reporting the Dunlops “lasted and lasted and lasted” compared to Michelins that “only lasted 2,700 miles.”
The set has 113 ratings averaging 4.7 stars, and the most-praised aspects are overall tires and value for money (7 and 5 mentions). There are no mixed or negative aspect counts, which suggests a very satisfied owner base. The load range is L, which is slightly lower than the M rating of many sport-touring tires, but it is still perfectly adequate for the Z800 in solo/light touring use. The GPR-300 is not the sharpest-handling tire on this list — the S22 and the ContiSportAttack 2 are more responsive — but for riders who simply want a reliable, long-wearing set that does not break the bank, the Dunlop GPR-300 is a smart, proven choice.
Why riders choose it
- JLB rear construction provides a smooth, consistent tire patch for predictable handling
- Owners repeatedly note excellent tread life
- Two-tire set simplifies the buying process; no need to match a front tire separately
The honest trade-off
- Handling is good but not razor-sharp — riders looking for maximum feedback will find the S22 or the Road 5 more communicative
- Load range L is slightly lower than M-rated sport-touring tires; fine for solo riding, less ideal for heavy two-up loads
A proven value set: Z800 owners who want a reliable no-surprises tire set with a focus on tread life and consistent feedback should reach for the Dunlop Sportmax GPR-300.
One caveat: If you need maximum wet-weather confidence, the MICHELIN Road 5’s siped design offers noticeably better rain traction than the GPR-300’s standard radial tread.
9. Continental ContiMotion Sport/Touring Motorcycle Tire Rear 180/55-17
An entry-level radial that still delivers German-engineered ride quality and stability.
The ContiMotion is Continental’s concept radial for the entry-level market, and it manages to pack impressive features for a budget-friendly tire. The 0-degree steel-belt construction on the rear provides excellent high-speed stability and ride comfort, while the newly formulated polymers in the tread compound extend mileage without the tire turning hard and slippery as it wears. Owners praise the grip, with one stating the tire “sticks like glue” on dry asphalt and noting it saved their life during an emergency maneuver. The ride quality and traction are consistently praised across 244 ratings (4.4-star average).
Stability receives a mixed verdict in the aspects list (6 mentions), but no single negative aspect stands out — the ContiMotion is a reliable tire that performs above its price tier. The load capacity is 315 kilograms (approximately 694 pounds), which is lower than the 805-pound standard of most tires on this list. For a Z800, that is adequate for solo riding and light luggage, but heavy two-up touring or extended high-speed running may push the tire to its limits. The ContiMotion is a fantastic budget choice for new riders or those who want a predictable, safe tire for commuting and moderate weekend riding.
Safe and stable on a budget: The ContiMotion’s 0° steel-belt construction gives it a stable, planted feel at highway speeds that rivals more expensive sport-touring tires.
Who this is for: Budget-conscious Z800 riders who want a safe, durable radial with predictable dry and wet grip — and who ride solo without heavy loads. The ContiMotion delivers genuine Continental quality at a price that keeps your wallet happy.
What to be aware of: The 694-pound load capacity is lower than the standard 805-pound rating of rivals; it is fine for solo street riding, but two-up touring or aggressive canyon work may push it past its comfort zone.
10. KENDA KM1 Rear Tire 180/55ZR17 (040015517B1)
The lightest Kenda KM1 option — and one that hits 140 mph without a wobble.
This version of the Kenda KM1 is differentiated from the sport-touring (B09QXJRVT2) variant by its weight: 12.4 pounds compared to the 17.7 pounds of the other Kenda KM1 SKU, making it noticeably lighter and less cumbersome during mounting. The advanced radial construction uses a proprietary rubber compound that reaches optimal operating temperature quickly. Owners confirm the tire’s confidence on fast highway riding — one says they “took the tire up to 140mph on a Yamaha MT07 and nothing!”
With an 805-pound load capacity and a W-speed rating (over 168 mph), the tire is built for speed stability. The long-wearing compound technology is designed for extended mileage, and owners note the tire is “strong on the road” and offers “excellent value for money.” Quality and value for money lead the positive aspects (14 and 11 mentions). The trade-off, as one owner put it, is that the tire is “very slow to respond” compared to premium sport rubber — it earns a C-plus for performance and a straight A for longevity. For the Z800 rider whose priority is safe, budget-friendly touring with occasional highway blasts, this Kenda KM1 is a sharp buy.
The biggest wins
- 12.4 pounds makes it the lightest Kenda KM1 option — significantly easier to mount and reduces unsprung weight
- W-speed rating certifies the tire for sustained high-speed cruising over 168 mph
- Long-wearing compound is praised by owners for strong road durability and cost-effective mileage
The compromise
- Performance-oriented riders say the tire is “very slow to respond” compared to the Michelin Road 5 or S22
- Cornering is not as sharp — better suited for straight-line touring than aggressive canyon riding
The budget tourer: This Kenda KM1 is the right rear tire for Z800 riders who cover long highway miles and want a cost-effective, long-lasting radial that does not sacrifice high-speed stability.
Who should look elsewhere: If you regularly attack twisty roads and need responsive cornering, the S22 or the Road 5 offer far sharper turn-in and mid-corner feel.
Understanding the Specs
Speed Rating: W vs ZR
The speed rating on a tire’s sidewall tells you the maximum speed it is certified to handle under proper inflation. A “W” rating (like on the MICHELIN Road 5, Pirelli Angel GT, and Kenda KM1) means the tire is load-tested up to 168 mph. A “ZR” designation means it exceeds 149 mph but does not set a specific upper cap. For the Z800, which can push past 150 mph, a W-rated tire provides a clear safety margin for high-speed highway cruising or track sessions.
Load Index and Load Range
The load index is a number (73, for most tires on this list) that corresponds to a per-tire weight limit in pounds. Load index 73 equals 805 pounds — more than enough for a Z800 plus a rider and gear. The MICHELIN Road 5 breaks from the pack with a load capacity of 890 pounds (still load index 73, but with a higher load range M). Load range M indicates a standard passenger-car/light-truck load, while L (on the Dunlop GPR-300) is slightly lower. Always match or exceed the bike’s stock load index for safe riding.
Treadwear Indicators and Dual-Compound Design
A dual-compound tire (often called 2CT or bi-compound) uses a harder rubber strip in the center of the tread for straight-line durability and a softer rubber on the shoulders for cornering grip. The Michelin Pilot Power 2CT uses a 20-percent softer edge mix, while the Pirelli Diablo Rosso III uses a soft side stripe starting at mid-lean. This design gives you the best of both worlds: long highway life and sticky edge grip, but it wears unevenly if you do most of your riding in straight lines.
Siping and Wet-Traction Technology
Siping refers to the tiny slits cut into the tread blocks. These slits open on wet pavement, creating edges that grip the road and channels for water to escape. The MICHELIN Road 5’s XST EEvo sipes are the most advanced example on this list — they keep the tire stopping as short after 3,500 miles as a brand-new Pilot Road 4. Look for silica-rich compounds (like the Bridgestone S22’s fine-grain silica) that bond with water molecules to improve traction on slick surfaces. A tire without siping or silica is a dry-weather-only choice.

Final Thoughts: The Verdict
For most riders, the best z800 rear tire winner is the MICHELIN Road 5 because it combines superior wet-weather traction, dual-compound longevity, and the highest load capacity on the list — all backed by 589 ratings averaging 4.9 stars. If you prioritize the stickiest cold-weather grip for aggressive canyon carving, grab the Bridgestone Battlax Hypersport S22. And for the budget-conscious rider who still wants serious mileage, the Kenda KM1 is the value champion that tens of thousands of owners trust. The crowd favorite across nearly a thousand owners is the KM1’s value package — but for year-round confidence on a Z800, the Road 5’s grip on wet pavement is the real differentiator.
