Triumph confirms new Moto2 engine is NOT based on Tiger Sport 800 or Trident 800

Ever since Triumph revealed it would replace its long-serving 765cc Moto2 engine with a new 800cc triple from 2027, one question has dominated the conversation. Which road bike does it come from?

With Triumph recently launching its new 798cc platform in the Tiger Sport 800 and Trident 800, many assumed the answer was obvious. It isn't.

Speaking to Visordown, Triumph Chief Product Officer Steve Sargent has confirmed the new Moto2 engine is not based on the Tiger Sport 800 or Trident 800. More importantly, he revealed the company has fundamentally changed how it develops its Grand Prix engines.

When Triumph joined Moto2 in 2019, it started with the Street Triple's production 765cc triple before developing it into a dedicated race engine. This time, the process has been reversed.

"We'd already developed the 765 engine before the discussions with Dorna," Sargent explained. "It was a production engine that we then developed into a Moto2 race engine. This time it's different."

Rather than asking how much more performance could be extracted from an existing road bike engine, Triumph first worked out what Moto2 needed from its next-generation powerplant.

"We started by asking what we needed to do to move Moto2 forwards," he said.

"With the current 765 we've probably reached the right balance between performance and durability, so it wasn't really about tweaking the existing engine. It meant making more significant changes."

Those changes include an all-new cylinder head and a broader redesign of the engine package, resulting in an engine that produces around six per cent more power while shedding approximately two kilograms.

The result is a Moto2 engine which we assume will make somewhere around 150bhp, but Sargent says peak power was only one objective. Riders will also benefit from noticeably stronger torque throughout the rev range, allowing them greater flexibility with gear selection while making the bikes easier to drive out of slower corners.

"The riders will absolutely notice six horsepower, [at the top]" he said. "They'll also notice the increased torque across the rev range."

The lighter engine also changes the bike's centre of gravity, meaning every Moto2 chassis manufacturer will need to develop an entirely new frame for 2027.

While lap records are an obvious target, Sargent believes teams may need time to unlock the full potential of the new package.

"It wouldn't be right if we came out and said we'd built a lighter, more powerful engine but weren't expecting it to be quicker," he said. "We might not see records immediately, but I'd certainly hope we'll start seeing lap records fall during the first season."

So, it’s not the Tiger Sport. Not the Trident. So what is it?

Sargent stopped short of revealing the origins of the new engine, but he was unequivocal about what it isn't. Asked whether it shared its architecture with the recently launched Tiger Sport 800 and Trident 800, he replied simply: 

"It's categorically not the Tiger Sport 800 engine. It's a completely different set-up."

That leaves the identity of Triumph's new triple as one of the biggest technical mysteries heading into the 2027 Moto2 season, but that might only be because we haven’t seen the road-going bike that will also use this motor. Despite its racing-first origins, Sargent hinted that the relationship between Moto2 and Triumph's road bikes will continue, and the ‘race to road’ ethos at Triumph is still strong, and that’s unlikely to change.

"We've always said the Moto2 engine and our road bike engines feed into one another," he explained. "Inevitably, some of what we're developing for Moto2 will find its way into production motorcycles."

While he refused to say when that might happen, the comments strongly suggest Triumph's next generation of performance triples could owe more to Grand Prix racing than ever before. It also hints at a future model that could thrust Triumph into the new-breed supersport class. Bikes like the Yamaha R9 and KTM 990 RC R are making big waves in the hands of private riders and pro-racers right now. With Triumph’s seeming lack of interest in putting a fairing on the Street Triple and calling it a Daytona, perhaps this is the route Triumph is taking.

And when you think about it like that, it makes perfect sense. Having a bike that you can say is born from the exact same mechanical DNA as a Grand Prix Moto2 bike is a PR and marketing wet dream, and something that no other motorbike manufacturer on the planet can claim.

It would also be significant because this will be the first time in the Moto2 era that a truly race-bred engine has competed in the series. Sure, the Honda CBR600R engine that ruled the Moto2 roost until 2018 (and then Triumph hoovered up all the lap records) had massive success on the track, but it was still a homologated engine that was sold to punters, just like the 765 is. That change represents a significant shift in philosophy, and could ultimately prove just as important as the extra 35cc.
