The manual states a 5 kg load limit for the top case, compared with 10 kg for a side case. This is not an oversight: behind the seat, the weight sits high and far from the center of gravity, and every extra kilo is noticeable when cornering and braking. Forty liters is a lot precisely because whatever you put in it needs to be light.

The same patented quick-release mechanism as the side cases, with nine contact points on the plate. On the top case, the play is more noticeable than anywhere else because the weight oscillates higher up: eliminating that play means a motorcycle that doesn’t sway at the rear and mounts that last.

On the front side, there is a padded backrest shaped to follow the curve of the back. It’s a detail that doesn’t appear in the technical specifications, yet it determines whether the passenger gets back on after the stop.

Forty liters in an almost cubic form factor, weighing 5.59 kg empty. These are the maximum dimensions with the accessories installed, measured manually by the manufacturer and therefore subject to a small tolerance. LOBOO does not state the internal dimensions: if you need to know whether a specific helmet will fit, ask us first.

LOBOO states that it uses a high-strength aluminum alloy. On a top case, this matters mainly if the bike tips over while stationary, when the entire weight of the motorcycle lands on one corner: a softer alloy stays bent, while a harder alloy gets marked but holds its shape.

The treatment is anodizing, not paint applied over the metal. That means a scratch remains a scratch and does not become the point where the paint starts peeling and oxidation begins underneath. On a part that stays outdoors year-round, that is what determines how it ages.

The corners have structural plastic protectors that scrape instead of the aluminum. They also come in handy on a top case in the garage, when the motorcycle touches the wall or another motorcycle while parked.

Water resistance depends not on the shell but on the joints. LOBOO states that there are rubber seals around the lid, German rivets, and Swiss structural adhesive at the connections: these are the three points where water gets in, when it does.

CNC-machined aluminum sealing frame integrated into the lid, rubber gaskets, German rivets, and Swiss adhesive: that’s what LOBOO claims. It does not publish an IP rating for the top case, and we won’t make one up.

Aluminum alloy hinge with an integrated opening stop: the lid stays open while you load, instead of closing by itself. On a top-opening top case, often with your hands full, this matters more than on side cases.

The lock cylinder can be removed and replaced, and the manual explains how to do it. This means the top case and side cases can all be operated with the same key, instead of carrying three different keys in your pocket. Write down the number printed on the key: without it, getting a replacement is complicated.

Aluminum alloy handle for carrying the detached top case without straps that cut into your fingers. Detaching it and carrying it inside is the easiest way to empty it and avoid leaving anything on the motorcycle.

High-strength anodized aluminum alloy: a scratch stays a scratch; it does not become a spot of oxidation. The structure is riveted, and the manufacturer states that the components can be replaced individually, so a broken part can be replaced instead of condemning the top case.

In the lid, there is a pocket held in place by elastic straps for documents, tools, and small items that would otherwise end up at the bottom, beneath everything else, in a forty-liter bag.

The interior walls have a flocked, velvety-touch lining. The helmet rests on that instead of on the metal, and the top case doesn’t transmit every bump like an empty box.

An aluminum bar runs all the way through the lid: you can thread a strap through it and secure a tent, sleeping mat, or waterproof bag. Keep in mind that the top case’s stated load capacity is 5 kg, and the item secured on top must be within that limit.

The manufacturer’s specification: an aluminum-alloy body, stainless-steel or aluminum top-case plates, and black and silver color options. That is everything LOBOO states about the series’ materials, and we are not adding anything else.
