Triumph unveils its new bike for the Supersport World Championship – with increased engine capacity

Since 2022, the Supersport World Championship has been governed by the next-generation regulations, which have seen the classic 600cc four-cylinder bikes replaced by machines with significantly larger engine capacities. Honda continues to compete with the CBR600RR, whilst Kawasaki has increased the ZX6R’s displacement to 636 cc. All other manufacturers involved – Ducati, MV Agusta, QJ Motor, Triumph, Yamaha and ZX Moto – now have motorbikes with capacities ranging from 765 to 955 cc.

At the end of June, SPEEDWEEK.com reported on Triumph’s plans to compete in the Moto2 World Championship from 2027 onwards with a larger engine. When news of the increase in engine capacity for the middle GP category leaked out, it became clear that there would also be a production model featuring this engine. This, in turn, means that there will also be a new homologation model for the Supersport World Championship.

Simon Buckmaster’s PTR team has been working on developing the new machine for months; a test took place in Aragon on 25–26 August, during which next year’s Michelin tyres were also used. Jorge Navarro was the rider. However, it is still unclear whether PTR will continue to partner with Triumph in 2027; there are also talks between Buckmaster and the Chinese brand QJ Motor. New to Triumph is Marc Griffith’s Renegade team , which is set to receive factory status.

Triumph: As well as the engine, the chassis is also new

Triumph has now unveiled the new motorbike. The new three-cylinder engine has a capacity of 798 cc instead of the previous 765 cc and complies with the Euro 5+ emissions standard. The increase in displacement is not achieved simply by boring out the cylinders; the stroke has also been increased, although Triumph will not reveal the exact dimensions until 17 November. The 765 engine, with dimensions of 78 x 53.4 mm, is already designed with a fairly short stroke. There is no longer a conventional exhaust; the entire exhaust system is located beneath the engine and is largely concealed by the front fairing.

Fans could hardly believe their eyes at what they witnessed at the Bahrain Grand Prix: cars crawling along, racing cars that simply came to a standstill. The FIA narrowly avoided a fiasco like the one at Indy in 2005.

Alongside the revised engine, the Street Triple features a modified aluminium chassis with optimised stiffness distribution. The rear wheel is mounted in a significantly more robust swingarm. The central shock absorber is fitted much more upright in the chassis than on the Street Triple 765. Also new is the rear section of the frame, which positions the rider higher and closer to the handlebars. The design has been completely overhauled.
