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 R1100S Motorcycle - Street (1998-2005)
The BMW R1100S, produced from 1998 to 2005, is a distinctive sport-tourer powered by a 1,085 cc flat-twin "oilhead" boxer engine. This air-cooled cylinder and oil-cooled head engine consistently delivered 98 horsepower and 97 Nm of torque, paired with a six-speed transmission.
A key mid-cycle enhancement occurred from December 2002 (for 2003-2005 models), introducing dual ignition with two spark plugs per cylinder to address engine surging. The core engine specifications remained consistent.
Throughout its production, the R1100S was offered in a Standard model, the R1100S Sport (featuring stiffer suspension, a steering damper, and a wider rear wheel), and from 2003 to 2005, the track-focused BoxerCup Replika (BCR). The BCR included performance upgrades like Laser exhausts, braided brake lines, carbon-fiber components, Öhlins suspension, and a shorter paralever torque arm for quicker steering. Later Sport and BoxerCup models also featured matte black engines with silver cylinders. Q: How do I ensure I select the correct parts for my R1100S?
A: Please use the year and edition selector on this page to confirm compatibility for your specific BMW R1100S model.
