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
KTM 890 Duke Motorcycle - Street (2020-2023)
The KTM 890 Duke series, produced from 2020 to 2023, represents a significant evolution in the naked sportbike category. These motorcycles are powered by an 889cc liquid-cooled, DOHC parallel-twin engine, offering a blend of power and agility. The year 2020 saw the introduction of the 890 Duke R, marking a significant transition from the 790 Duke with a larger displacement engine and performance-oriented components. In 2021, the standard 890 Duke model was launched, sharing the same 889cc engine but with slightly different tuning. The lineup expanded in 2022 with the arrival of the 890 Duke GP, primarily an aesthetic variant. While power adjustments were observed between the R, standard, and GP versions, the core 889cc parallel-twin engine remained central to the series throughout this period. FAQ:

Maintenance
| Component | Interval | Details |
| Engine Oil and Oil Filter | Every 15 000 km or annually | Change engine oil and filter at every service. KTM recommends Motorex Power Synthetic 4T 10W/50 oil. More frequent changes (5 000-6 000 km) are suggested for hard riding. |
| Belt | The KTM 890 Duke uses a chain drive, not a belt drive. The chain, sprockets, and chain guide should be checked at every service. Chain cleaning and lubrication recommended every 800 km. | |
| Spark Plug | Every 30 000 km | Replace spark plugs during major service. The recommended spark plug is NGK LMAR9AI-10. Some advice suggests checking every 8 000 km and replacing every 15 000 km for normal use. |
| Air Filter | Every 15 000 km | Change air filter and clean airbox. More frequent checks and cleaning (every 2 000-3 000 km) are advised in dusty conditions, with replacement every 5 000-7 000 km if needed. |
| Coolant | Every 2 years | Use KTM-approved coolant, such as Motorex Coolant M3.0. Check level monthly. |
