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
BMW R1150GS Motorcycle - Street (1999-2006)
The BMW R1150GS, produced from 1999 to 2006, is a renowned adventure touring motorcycle. It features an 1130cc air/oil-cooled flat-twin boxer engine, consistently delivering 85 horsepower and 98 Nm of torque across all model years. This model succeeded the R1100GS and was later replaced by the R1200GS. During its production, the R1150GS saw significant evolution. Introduced in 1999, it featured a new 1130cc engine, a six-speed gearbox, and distinctive asymmetric headlights. In 2001, the more off-road-oriented R1150GS Adventure was launched, offering a larger fuel tank, increased suspension travel, and a conventional sixth gear. Late 2002 brought further updates, including twin spark ignition to improve emissions and address surging, and the introduction of an optional electrically servo-assisted combined braking system. These changes mark distinct phases in the model's development. FAQ:
