Triumph Motorcycles has unveiled an updated race engine that will power the Moto2 World Championship beginning in 2027. It represents what the brand calls the most significant technical overhaul of the British manufacturer’s control engine package since it replaced Honda as the series’ exclusive supplier in 2019. According to Triumph and MotoGP, track testing of the new 2027 Triumph Moto2 engine will begin in the coming months ahead of its competitive debut.

Since entering the Moto2 championship, Triumph has campaigned a race-tuned variant of its 765cc inline-triple engine, derived from its popular Street Triple 765 family of naked sport bikes. Over the past seven seasons, the engine package has accumulated over a million competition miles (1,196,843 miles, to be exact), helping achieve nearly 100 all-time and race lap records. Triumph credits the extensive race mileage and rider feedback as being instrumental in bringing the next iteration of its race-spec engine to the paddock.

Although the new race engine remains based on Triumph’s three-cylinder architecture, it receives substantial internal revisions to increase airflow and overall performance. The centerpiece is a completely new cylinder head, featuring redesigned intake ports, a new combustion chamber, and an all-new, low-inertia valvetrain. Triumph says the revisions increase the compression ratio while delivering additional torque across the rev range.

To support the higher output, engineers also redesigned the crankcases and all internal components to improve durability under increased loads. Collectively, the changes also reduce engine weight by 4.4 pounds (2 kilograms).

Triumph has confirmed the new powerplant produces approximately 6% more peak power than the current Moto2 engine and will “see a change in capacity,” adding that more information will be made available soon. However, the manufacturer has not disclosed the new displacement, bore and stroke, peak horsepower, torque, or maximum engine speed, stating only that additional technical information will be released later.

For context, MotoGP has previously stated the current Triumph Moto2 engine produces more than 138 horsepower in race trim. Applying Triumph’s announced 6% increase would theoretically place the new engine in the neighborhood of 146 horsepower. Likewise, any increase in torque remains purely speculative.

Critically, we need to note what this means for the Street Triple lineup. Triumph confirmed in its public statement that the race-spec Moto2 engine will “see a change in capacity” for the upcoming 2027 season. The current Street Triple 765 platform has benefited throughout its lifecycle from updates directly linked to the development of the race-spec 765 engine. As a result, we may see a change in displacement for future Street Triple motorcycles that could possibly be influenced by the race-engine’s development.

The British firm also stated that its new engine package will require substantial changes beyond the powerplant itself. Triumph says every Moto2 chassis manufacturer (currently Kalex Engineering, Boscoscuro, and Forward) will need to develop an entirely new chassis for 2027 due to revised engine mounting points and a different intake layout. Work with chassis constructors has reportedly been underway for the past 12 months, with private testing scheduled before the engine’s on-track debut later this year. These chassis-related statements are telling, as they confirm that the changes will be significant.

With the announcement of this new race engine, Triumph is also reconfirming its commitment to the Moto2 World Championship through the 2029 season.
