Triumph is continuing to develop its screaming triple, with the unit to be used in the 2023 Moto2 season gaining more power and more revs. The 765cc engine has been powering these racers since 2019, making 2023 its fifth year in service.
The net gains are an extra 5PS and an extra 400rpm at the redline, thanks to a new cylinder head, which brings with it an increased compression ratio, longer valves and revised springs, that work together with a revised cam profile. The pistons, conrods and crankshaft have also been strengthened to cope with the resulting 5.8 per cent increase in piston pressure. Overall, the 765CC three-cylinder engine is now capable of producing over 140PS (103kW) in race trim.
“We are incredibly proud of the way that our 765cc triple engine has redefined the Moto2 category, making it faster, more competitive and better sounding,” said Steve Sargent, Triumph’s Chief Product Officer.
“When there’s such a fundamental change to a category everyone embarks upon a journey of learning – the riders and teams in terms of becoming attuned to the characteristics of the triple and optimising the overall package of engine, electronics and tyres, and us as Triumph in terms of performance potential and reliability.
“We have achieved very nearly 1 million competitive kilometres on the current-spec 765cc Moto2™ engine and that gives us enormous confidence as we take this next step to give the riders something they all want – more revs and more power. We look forward to seeing yet more lap records fall as laptimes get faster, and how more power gives riders more freedom to create overtaking opportunities and are excited to begin the next chapter of Moto2 powered by Triumph.”
One million race kilometres is an awful lot of circumstantial test milage, should Triumph decide to put a version of this engine into service in a true Daytona successor. It’s what everyone’s been asking for and what Triumph consistently refuses to comment on. We wait in hope.
