Triumph introduces its biggest update since becoming the Exclusive Engine Supplier for Moto2™ in 2019—a full race gearbox for the 2025 season. The key change is a new gearshift pattern where neutral is now positioned at the top and locked out, preventing riders from shifting through neutral during races, ensuring seamless performance.
This redesign features a new selector drum with revised tracks, optimizing gear engagement. The billet-machined components provide ideal mass and inertia, while a mechanical neutral lockout allows riders to shift freely between 1st and 6th gear. Neutral can only be engaged manually, ensuring precision for pitlane and start-line use. The gearbox is housed in a newly developed crankcase designed specifically for the 2025 Moto2™ engine.
EXCLUSIVE ENGINE SUPPLIER
The new Moto2™ engine is a race-developed 765cc Triple engine based on the powerplant from the class-leading Street Triple RS, with improvements that allow the engine to breathe more freely and rev harder than the production bike, and a peak power figure of more than 140PS.
