British manufacturer provides sneak peek of its 250F dirt bike powerplant.

August 15, 2023

About two and a half weeks after giving the public a first look at the chassis of its yet-to-be-released dirt bikes, Triumph has done the same for the engine of its 250cc four-stroke motocross model. Although specs have yet to be released, we can tell it’s a fuel-injected liquid-cooled DOHC four-stroke 250cc single-cylinder powerplant.

“This engine has its own identity and I think one of the best things about it is the way that it’s designed and developed, which enables riders of a very wide range of abilities to be able to ride the bike. It’s light and compact, and the power delivery is great for all forms of riders.” —Ricky Carmichael, Triumph global off-road ambassadorTriumph

In the video above, global off-road ambassador Ricky Carmichael, test rider Ivan Tedesco, lead chassis engineer Dave Arnold, US Triumph Racing team principal Bobby Hewitt, US Triumph Racing team manager Steve “Scuba” Westfall, and Triumph Racing MXGP team manager Vincent Bereni have a roundtable conversation about the development and performance of the engine.

The next episode is scheduled to publish on Tuesday, September 5, where Carmichael will ride the bike and more information about it should be released.
