In MotoGP, the engines are getting smaller – in Moto2, they’re getting bigger!

A new era will begin in the MotoGP World Championship in 2027, when Pirelli takes over as the sole tyre supplier, engine capacities are reduced from 1000 to 850 cc, and height-adjustable chassis are phased out. All five manufacturers involved – Aprilia, Ducati, Honda, KTM and Yamaha – confirmed their commitment to the series for a further five years, until the end of 2031, on 19 June during the Brno weekend.

There will also be changes in Moto2. In 2019, Triumph took over as the supplier for the middleweight category and has since been providing 765 cc three-cylinder engines; the current contract runs up to and including 2029.

Moto2 is modelled on the production series

The basis of the Moto2 engine is identical to that of the Street Triple 765 RS, which is used in the World Supersport Championship. SPEEDWEEK.com has discovered that this motorbike will be fitted with a new 800 cc engine for 2027. It therefore stands to reason that this three-cylinder engine will also be used in Moto2 in future.

“We’ve always said that the development of the Moto2 and production engines goes hand in hand,” confirmed Steve Sargent, Triumph’s Chief Product Manager, to SPEEDWEEK.com. “Whatever we develop for Moto2 will also form part of a production motorbike. In Moto3, the engine capacity is also being increased. We have to bear in mind where the promoter wants Moto2 to sit between the other two classes. The step up from Moto3 to Moto2 mustn’t be too big; the same applies to the step up from Moto2 to MotoGP. We have to ensure that this balance is right. At the same time, we must bear in mind that the engine we are developing must also meet the needs of the market.”

The increase in engine capacity will have far-reaching consequences, as chassis manufacturers Kalex, Boscoscuro and Forward will have to adapt their frames. In the cylinder head area, the mounting points for the new Triumph engine will be modified; there will also be differences from the current versions around the airbox.

The chassis manufacturers will have to redesign a number of components, which is why only 2027 model-year products will be used next season. Some teams are currently using spare parts from previous years, but this will no longer be possible.
