More power and less weight for Triumph Moto2 engine
Triumph has been busy tweaking, tuning and improving its Moto2 engine for next year’ s race season. The 765cc three-cylinder, which is found in Triumph’ s Street Triple 765 RS as well as the race bikes, will see a 6 % increase in power – not an insignificant amount in the ultra-competitive world of motorcycle racing
n Triumph started the project by analysing data it had captured from the 1,196,842 miles its race engines have cumulatively amassed since 2019, when it was first used in Moto2. It also listened to feedback from the riders to help decide what areas were most crucial to improve.
To eke out even more horsepower from the 765cc motor, Triumph focused on better airflow. The new 2027 race engine has an improved cylinder head with a new combustion chamber designed to create a higher compression ratio. It also has better-flowing ports and a lighter valvetrain. The results are not just a higher power figure, but more torque throughout the rev range.
Power isn’ t the only important factor in a race engine; weight is essential to keep in check too. While reinforcing an engine to help it cope with the extra power would ordinarily make it heavier, miraculously, Triumph has been able to shave 2kg thanks to a new crankcase.
The new, more powerful and lighter three-cylinder engine will be used in the 2027 Moto2 World Championship. Triumph has been working with the chassis manufacturers for the last 12 months to ensure the engine is reliable and durable for the next season of racing.
