The Trekker Alaska Top case holds one modular helmet. Featuring the MONOKEY® fixing system, which allows for a single lock to open and release the plate with the same key. Compatible with all Monokey plates, apart from those with the stop light kit connection.
Like the Trekker ALASKA side case, it comes in two finishes: Natural and Black. The clean, minimal aesthetic pairs well with the rest of the range, and prioritizes practicality of use. Particular care has been devoted to ensuring the product is durable and repairable: the removal system, the stabilizers at the bottom, the base and other components can be easily replaced, greatly extending the useful life of the top case.
Features
- WIRELEASE® SYSTEM: the cases are released from the plate by turning an external knob that is equipped with a cable system (Patented), placed directly under the Security Lock. It is not necessary to turn the knob to attach the cases.
- Two handles placed on the back of the top case, which are also integrated with the strong hinges on the lid, allowing the latter to open more fully without the need for classic retention cables: once opened, the lid is held in position in order to make packing/unpacking easier.
- Four belt-strap loops integrated into the structure of the lid, set into the contoured lid to give an elegant shape to the whole case.
- Set up to allow the attachment of a backrest (available for purchase as an optional) using screws, without the need to pierce or attach any component with adhesive;
- Rivets fitted with gaskets and sealed using silicone, ensuring watertightness even under the worst riding conditions.
- A series of grips built into the interior, integrated into the supporting structure, allowing loads to be attached to both the lid and bottom of the case.

Vehicle Information
Triumph Bonneville Motorcycle - Street (1959-2026)
The Triumph Bonneville, an iconic British motorcycle, boasts a rich history from 1959 to 2026. Celebrated for its classic styling and parallel-twin engine, it has evolved through two distinct production eras while retaining its legendary character. The original Meriden factory produced models from 1959 to 1983 (with a brief revival in 1985-1988), featuring 650cc (T120) and later 750cc (T140) air-cooled engines. Key changes included the shift from pre-unit to unit construction in 1963 and the introduction of a 5-speed gearbox and disc brakes. After a hiatus, the modern Hinckley era began in 2001, reintroducing the Bonneville with contemporary engineering. This period saw engine displacements increase from 790cc (2001-2005) to 865cc (2005-2016), and then to liquid-cooled 900cc and 1200cc engines from 2016 onwards. A significant transition from carburetion to fuel injection occurred around 2008. The model range expanded significantly, with various trims like the T100, T120, Bobber, and Speedmaster. Updates for 2026 include enhanced features like larger fuel tanks, updated bodywork, and advanced electronics for several models, ensuring its continued relevance. FAQ:
