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 K100 Motorcycle - Street (1983-1986)
The BMW K100, produced from 1983 to 1986, is an iconic motorcycle known as the "Flying Brick." It marked a significant shift for BMW with its water-cooled, inline four-cylinder engine. All models from this period featured a 987 cc engine producing 90 horsepower (66 kW) at 8,000 rpm and 84-86 Nm of torque between 6,000 and 8,250 rpm, utilizing a Bosch LE-Jetronic fuel injection system. Several trims were available, including the basic K100, the K100 RS (sport-touring, introduced in 1983), the K100 RT (super touring, launched in 1984), the K100 C with a small cockpit fairing, and the K100 LT (Luxury Tourer, introduced in 1986). While the core engine remained consistent in terms of displacement and power output between 1983 and 1986, BMW implemented minor adjustments and updates over the years. These revisions included changes to the starter clutch, modifications to the fuel gauge system (transitioning from a thermistor to a potentiometer in 1986), and adjustments to the footpeg mounts. There was no major generation break or significant platform change during this period. Q : How can I ensure parts compatibility for my BMW K100?
