Drops the bulky fender and gives the Z125 a clean, sportbike tail in under an hour.

This aluminum license plate bracket uses a black powder coating that resists rust from road salt and rain. The structure is CNC-cut using turret punch presses, which makes it more durable than stamped steel brackets that can bend. It measures 7 inches by 6.5 inches, and it fits Z125 and Z125 Pro models from 2015 through 2023. All the hardware and installation instructions are included; you just remove the stock screws and lamp wires, then bolt this on. The owner praise most consistently highlights value for money — 10 separate owners call it a great buy for the price, especially compared to pricier alternatives like the Integrated LED Tail Light that costs more for similar visual impact.

The only tricky spot is the stock turn signals: the fit of the OEM signals into the bracket is very snug, and some owners found the bushings tough to squeeze in. Once seated, the kit is sturdy and looks clean. It does not come with aftermarket turn signals, so you reuse your stock ones. If you want a fully custom rear end, this is the foundation piece that makes the biggest visual difference for the least effort.

One LED light replaces the entire rear cluster and plugs directly into the stock harness.

This MFC PRO unit combines a brake light, a position light (the running light that stays on), and integrated turn signals into a single smoke-lens housing. The lens is polycarbonate, which is impact-resistant and won’t yellow in the sun like acrylic can. It comes with a sub-harness that has wire pins already installed for the OEM connector, so you do not need to crimp or solder — you literally plug it in. It fits the Z125 Pro from 2017 through 2026. Owners mention it cleans up the rear perfectly and is noticeably bright, with one owner calling it “a simple swap.”

The fit is a frequent discussion point. The housing does not have the foam tape that the stock light uses to fill gaps, so some owners add a little foam tape on the edges to stop a slight wobble. A few note the integrated turn signals could be brighter for daytime visibility. If you are fine adding a strip of tape for a snug fit, this light gives you a modern, clean rear end in minutes. It also bolts onto Ninja ZX-6R and Z800 models, so the part has a wide track record.

Six reach positions and a short blade let you brake and clutch with just two fingers.

These Mokiton levers are ultra-precision machine-cut from aluminum, making them lighter than the stock steel levers. The short blade is designed for 2-finger or 3-finger operation, which is useful on a small bike like the Z125 where you want to keep more grip on the bar. The big feature here is the 6-position adjustment dial — you can change the reach distance from the bar to suit small or large hands without any tools. They are a direct replacement; no modification needed. They fit the Z125 Pro from 2017 through 2025, covering every model year available.

Installation hardware is included, and owners consistently say they fit perfectly and feel great. The red anodized finish adds a custom touch without looking aftermarket-tacky. The only thing to note is that these are short levers, so if you prefer the full-length blade that you can pull with all four fingers, these will feel different. But for riders who want quicker, more precise lever action, this is a near-perfect bolt-on. Compared to the Budget Lever Upgrade set, these offer more adjustability positions (6 versus a basic adjustable reach) and cover more model years (2017-2025 versus 2017-2020).

A grippy, handcrafted seat cover that clings to you and the bike like a gecko.

This seat cover is made with triple-stitched seams and steel rule die-cut panels, which means each panel is cut with a sharp steel die for an exact, repeatable fit on the Z125 Pro’s seat pan. It has traction ribs molded into the material to stop you from sliding forward under braking. It fits the 2017-2024 Z125 Pro models. The color option here is black with green ribs, which matches the classic Kawasaki green aesthetic. It is handcrafted in the U.S.A., and owners rave about the grip — one buyer says it “stays stuck to the seat like a damn gecko.”

Installation is straightforward if you have a staple gun and some patience; you pull the cover over the stock foam and staple it to the plastic seat pan underneath. The cover is only the top piece, not a full seat replacement. A few owners note that if you don’t pull it tight enough during installation, you can get wrinkles. But when installed correctly, the fit is glove-like and the grip upgrade over the slippery stock vinyl is dramatic, especially if you ride in the rain.

A maintenance-free GEL battery that holds its charge longer and resists spills.

This is a 12-volt, 3 amp-hour (3AH) battery rated at 50 Cold Cranking Amps (CCA) — enough to start the Z125 Pro reliably even in cooler weather, since CCA tells you how much starting power the battery delivers at freezing temperatures. GEL technology uses a thick paste instead of liquid acid, so it is non-spillable and safer if the bike tips over. It also has a slower self-discharge rate than standard AGM batteries, meaning it holds its charge better when the bike sits for weeks. It is a direct replacement for the YTX4L-BS form factor used in the Z125 Pro from 2017 to 2019.

The majority of buyers find it fully charged on arrival and drop it in with no trouble. The downside is rare but real: one owner reported a defective unit with a dead short that didn’t last two miles, and the return shipping cost nearly the same as the battery. Mighty Max covers it with a one-year manufacturer warranty, but you pay return shipping. For most riders, the GEL safety and the consistent starting performance make it a solid upgrade over a standard acid battery.

Factory-grade bearings that keep a race bike’s wheels spinning with zero issues after a season of hard racing.

All Balls manufactures these bearings to ABEC 3 precision (an industry standard for running smoothness and dimensional accuracy, equivalent to what many OEMs use). They use double-lip TC seals with stainless steel garter springs, plus a triple lip rubber seal design that keeps grease in and water and dirt out. The Chevron SRI 2 grease inside works from -29 degrees Celsius up to 177 degrees Celsius, so it handles both freezing starts and hot brake rotor heat. The kit is a direct OEM replacement for the Z125 Pro front wheel on 2017 and 2018 models, and it also fits the Yamaha YZ65.

Buyers confirm it fits the 2023 Z125 Pro front wheel with no issues, and one owner reports installing them in a YZ65 race bike where they survived several hard races without failure. At only 3.2 ounces, the bearings are lightweight but not fragile. The only catch is you need the right tools to press old bearings out and new ones in without damaging the wheel hub. If you are comfortable with basic wheel maintenance, this kit is the benchmark for smooth, long-lasting wheel rotation.

CNC-machined levers with adjustable reach that upgrade the feel and look of your controls.

These FTRT levers are milled from 6061-T6 aluminum (a strong, lightweight alloy used in aerospace and high-end bicycle parts) and finished with an anodized coating that resists oxidation. The pivot bolt is 304 stainless steel, so it will not rust. They are adjustable — you can change the distance of the lever blade from the grip to fit your hand size. They are a direct replacement for the stock levers on the Z125 Pro models from 2017 to 2020, and they also fit the Ninja 300, Ninja 400, and Versys-X 300. Owners praise the quality — it is the most-discussed positive, with 19 separate buyers calling it out — and the easy installation, which takes about ten minutes.

One note is that the brake lever has a slight wobble, as a few owners point out, but they still call it more comfortable than stock. The lever is not a folding design, so if you drop the bike, the lever tip may bend rather than fold away. For the price, this is a quality set that gives you adjustability and a better feel than the basic black levers that come on the Z125, and it is the most-reviewed lever option here, with nearly 200 ratings behind it. If you do not need the 6-position adjust of the Short Brake Clutch Levers, this set covers the same models for less.

Three adhesive rubber pads that kill the tank slide and add a factory-style accent.

This set includes a left-side protector, a right-side protector, and a central tank pad, all cut from PVC rubber with a very strong adhesive backing. The rubber material gives your knees and thighs a textured surface to grip when you brake or accelerate, preventing the side-to-side slide that happens with sweatpants or jeans on the stock painted tank. They fit the Z125 Pro from 2016 through 2023 and are finished in black with a glossy look. Customers note they stand out well and get compliments, with the appearance being the top praise point — 10 owners call them out for how good they look.

The adhesion gets mixed feedback. Most owners say the pads are super sticky and stay put, but in very hot conditions, a few report the edges lifting. Cleaning the tank surface thoroughly with alcohol before applying is critical for long-term hold. If you ride in the rain, the rubber grip is noticeably better than bare painted metal. The pads are thin, so they do not add bulky volume to the tank area. It is a small, inexpensive mod that makes a real difference in rider feel.
