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
Triumph Speed Twin Motorcycle - Street (1950-2026)
The Triumph Speed Twin, produced from 1950 to 2026, is an iconic model that spans two distinct eras. Originally launched in 1937, the classic Speed Twin made motorcycle history until 1966, setting the standard for parallel-twin engines. After a significant hiatus, Triumph reintroduced the name in 2019 with modern models. The classic period (1950-1966) featured the 5T model with a 498cc engine, followed by the 5TA from 1959, which boasted a 490cc unit construction engine (engine and gearbox sharing a common casing). Notable developments included the switch from a magneto/generator electrical system to a Lucas alternator in 1953, and the adoption of swinging arm suspension around 1955. The famous "bathtub" fairing was introduced with the 5TA, later abbreviated to "bikini" before being removed in 1966. Modern models (2019-2026) include the Speed Twin 900 (formerly Street Twin, rebranded in 2022) and the Speed Twin 1200. These motorcycles are equipped with liquid-cooled parallel-twin engines, 900cc and 1200cc respectively. They have received regular updates, including improved brakes, higher-spec forks, Euro 5 compliant engines, and the introduction of special editions such as the Chrome, Stealth, Cafe Racer, and TFC. These evolutions reflect Triumph's commitment to modernizing its classics while retaining their spirit. Q: Is this product compatible with my Triumph Speed Twin?
