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
Kawasaki Z900 Motorcycle - Street (2017-2026)
The Kawasaki Z900, a flagship model in Kawasaki's "Z" series, is a naked sportbike renowned for its balance of performance and handling. From 2017 to 2026, it has maintained a liquid-cooled, 948cc in-line four-cylinder engine, consistently delivering around 125 horsepower. While the 948cc engine displacement has remained consistent, the Z900 has undergone significant evolutions. In 2020, it received a major refresh, including revised styling, chassis enhancements, integrated riding modes, Kawasaki Traction Control (KTRC), a color TFT display, and Bluetooth connectivity. The year 2022 saw the introduction of the Z900 SE version, featuring upgraded suspension and brakes. For 2025, Kawasaki announced an update with new electronics, an electronic throttle, an updated ECU, and the addition of a six-axis Inertial Measurement Unit (IMU), enabling lean-sensitive traction control and ABS. The 2026 model is expected to integrate a bidirectional quickshifter and cruise control. The Z900RS, a retro-styled variant, was also offered. FAQ:
