7 Best Motorcycle Trunk | Trunks That Actually Lock and Latch

The cruiser-styled case that adds rear visibility and a passenger backrest in one.

This EGO BIKE trunk pairs a lockable backrest with a built-in tail light—two features that make it feel like a factory option rather than an add-on. The 20-liter ABS shell is the smallest capacity here, but the trade-off is a tidy profile that suits cruisers. A Honda Shadow owner reports the case lasted over 20 years, which tells you the plastic is genuinely tough even if it does not look premium.

Owners mention the install is straightforward on a flat rack, and the wiring for the strobe tail light is the main learning curve. The color code label is wrong, so owners suggest testing wires with a 9V battery first. The strobe connects to your running or brake light—not both—and the LEDs read a bit dim in daylight, though they look sharp at night.

Where this falls short of the VEVOR case below is capacity: it fits one standard or two half-shell helmets, but a full or modular helmet will not squeeze in. If you carry a modular lid, this is not the box. If you run a tidy cruiser and want a backrest plus lighting without a huge tail box, this delivers.

The cruiser trunk with room for two lids, a steel rack, and a padded passenger rest.

This EGO BIKE trunk brings a molded, upholstered backrest and a functional steel top rack—so you gain both passenger comfort and extra lashing points. The 30.48-liter interior swallows two helmets, which puts it ahead of the smaller EGO BIKE case above on pure hauling. The 15-pound weight is the direct cost of that size and the alloy steel reinforcement, so expect a firmer mount on your rack.

Owners consistently call it good value and like the looks, with the chrome steel rack drawing compliments. The practical reality, though, is that you need a flat luggage rack roughly 8″ x 8″ and some mechanical patience. Customers note drilling is required, the pre-drilled holes can misalign, and the locking mechanism is the weak point—several note the hinge and lock feel cheap and the light bar wires only run solid, with no blink or flow function after the first try.

Set expectations accordingly: this is a budget-minded touring box that looks the part and hauls a lot, but it asks for sweat equity on install. The lid rubber can work loose and cause noise—one owner fixed it with tape. If you love a project and want max cruiser storage for the money, this fits. If you want bolt-on simplicity, the VEVOR below is the smoother path.

A 45-liter aluminum case with a waterproof seal for daily commuting gear.

VEVOR builds this 45-liter case from 1.2 mm thick aluminum alloy with reinforced corner bumpers, and it shows in the hand—beefy latches, stainless rivets, and a powder-coated steel base plate. Owners who run it daily report it stays rattle-free at speed and keeps contents bone-dry through heavy rain and snow, thanks to the sealed lid. The quick-disconnect plate means the whole box pops off with one key when you park.

Capacity is this case’s party piece. At 45 liters it fits a full-face helmet plus gloves and small tools, with two inner pockets for a water bottle or umbrella. One owner even uses the box as a camp chair, noting it supports 200 pounds. The removable leather lining adds a premium feel, though a few note the padding itself feels a bit cheap—cosmetic, not structural.

Compared to the pricier Gurblofy case below, the VEVOR is easier to recommend for value because it pairs real aluminum construction with a 45-liter interior at a friendlier entry point. The one honest gripe: the “universal” mounting plate may need a few new drill holes to match your rack. Buyers on a TransAlp had to drill 4 fresh holes, so budget a little time with a drill.

A 55-liter aluminum case with dual-key locking for maximum cargo.

At 55 liters, this iproods case is the biggest capacity in the lineup—room for a heavy laptop bag and a helmet with space left over. The aluminum alloy and stainless steel shell gets a special coating treatment, with polymer resin reinforcing all four corners to absorb collision damage. The detachable PU lining cushions your gear, though it carries a slight odor when new that fades after airing out for a few days.

The dual-key system is the standout feature here. One key locks the interior; a second locks the mounting plate itself, so a thief cannot simply unbolt the box and walk off with it. Owners on a KLR650 mounted it in about 15 minutes with the included hardware, and a daily commuter reports zero flex in the lid and a well-sealed closure after weeks of use.

The honest trade-offs are the latch and the “aluminum” claim. The top latch can fail to seat until a tiny pebble gets cleared from the mechanism—one owner fixed it with a flashlight. And while the shell is marketed as aluminum, several reviewers point out it feels more like sturdy plastic with aluminum hardware. If pure capacity and anti-theft locking are your priorities, this delivers more space than the Gurblofy below at a lower price point.

A 45-liter aluminum case with bullet-proof locks and a waterproof seal.

Gurblofy’s 45-liter case uses a patented design inspired by sports dumbbells, and the quality landed it as a crowd favorite. Owners consistently rank the build quality as the top praise—the latches, liner, lid pockets, and waterproof seal all get strong marks, with one buyer saying it works as well as name-brand boxes costing four to five times more. The base plate mounted in under 10 minutes on an Africa Twin.

The locking system is the defining trait here. Buyers describe the two locks as bullet-proof, and the silicone-sealed construction keeps water and dust out completely. The 16.5 x 13 x 13-inch shell fits a full helmet plus daily essentials like gloves, a water bottle, and your phone. The advanced spray painting resists rust and corrosion, so it holds up in wet climates.

The one real drawback is spare keys. The key is a non-US design, and Gurblofy does not sell spares—lose the key and you are locked out for good. Buyers also note the mounting bracket may need light filing on some bikes like the Himalayan, and a few owners insist the shell feels like plastic rather than aluminum despite the marketing. If build quality and lock security matter most, this is the premium pick for a reason.

A 47-liter PP case with one-click quick release and an LED brake light.

Mingting built this 47-liter box from PP engineering plastic that is water-resistant, scratch-resistant, and fade-resistant, all at a weight of just 11.2 pounds. The one-click quick release is the headline feature: press the red button and the entire box detaches from the bike for easy carrying inside. It fits one full-face or two open-face helmets, with built-in tie-down straps to keep contents from shifting mid-ride.

Owners consistently call it a strong alternative to overpriced European cases—one K1300s rider compared it directly to a Givi costing over three times as much and found it solid, waterproof, and complete with a backrest. The built-in LED brake light is bright and easy to wire, and the CANBUS system on newer bikes enables both running and brake functions. The link lock bar prevents the lid from slamming shut on your fingers.

The trade-offs are the latch and the backrest pad. The lock is finicky on some units, needing a firm tap to seat, and the backrest is hard plastic rather than padded cushion. Buyers on a Ninja 250 note it fits an XL helmet plus gloves and almost a jacket, though it will not hold two full-size helmets. The heavy steel bracket is a plus for stability but adds install effort on some racks.
