Aluminium vs Plastic Top Cases: Which Is Right for Your Bike?
Aluminium vs plastic motorcycle top cases compared: strength, security, weather resistance and long-term value - from an aluminium top case manufacturer.

Aluminium or plastic? It is the first big decision when you choose a motorcycle top case, and it shapes everything from security to how the case looks after two summers on the bike. Here is an honest comparison from a manufacturer whose entire range is aluminium.
The Case for Aluminium
Strength comes first. A 1.2 mm aluminium alloy shell resists impacts, strap wear and rack vibration that can crack lesser materials.
Security pairs naturally with metal: stainless steel locks on the lid and base turn the whole case into a strongbox.
Weather resistance is built in. A waterproof gasket seals the lid, and a powder-coated finish stands up to sun, rain and road grime while resisting fading.
Where Plastic Fits
Plastic cases are typically lighter and come in a wide range of colours, which suits riders who prioritize weight and a specific look over maximum security.
The trade-off: plastic can fade in strong sunlight and become more brittle over years outdoors, and the lid is inherently harder to secure to the same standard as a metal shell with a double lock system.
The Verdict for Touring and Commuting
For adventure, touring, camping and any ride where you leave the bike parked unattended, aluminium is the practical choice: stronger, more secure and better sealed.
For short, fair-weather commutes on a small scooter or e-bike, a compact plastic box can be enough - though many riders still prefer the look and longevity of a small aluminium case, which is why our range starts at just 5L.
What to Check Either Way
Whichever material you choose, check the same three things: a locking system that covers the lid and the base, a gasket-sealed lid against rain and dust, and a quick-release, plug & play mounting plate included in the box.
Our Range: 5L to 65L, All Aluminium
