After nine seasons as the official supplier of engines for Moto2 – the class that replaced the former 250cc two-stroke class for 2010 – Honda will be replaced.Taking over is Triumph, which spent two years developing a spec-Moto2 engine. Triumph, which signed a three-year contract with Dorna (MotoGP commercial rights holder) to use its 765cc inline three cylinder in Moto2 from 2019 – 2021, has now unveiled the engine’s peak power output.
During an engine development press conference in Valencia alongside Externpro, Magneti Marelli and Dorna, Triumph says that the new triple will create 138 horsepower. This is up about eight on the spec Honda inline-four that derived from the CBR600RR.Triumph said that the motor’s development included a mix of factory-based, dynamometer and multiple track locations for testing. During the track tests, more than 2,500 “race pace” laps were completed at multiple European circuits that allowed Triumph to complete engine “double-lifecycle.”“Triumph have been extremely warmly welcomed by Dorna, its partners and the Press,” said Stuart Wood, Triumph Chief Engineer. “It really feels like people share our excitement in Triumph’s entry into factory supported, top flight motorcycle racing. We are confident that our engine development program has been extremely comprehensive and that the increased power, wide spread of torque and amazing triple sound will bring exciting racing in 2019.”The Triumph triple race engines are based on the Street Triple RS 765cc production engine, which produce 121 horsepower. It’s worth noting that the Street Triple RS derived from the Daytona Supersports 675cc bike.Triumph says “these new race engines are built to bring more power and torque, designed to rev harder and run with a lower inertia and all delivered in a lighter weight package.”The Moto2-spec engine has the following changes over the base Street Triple RS:
Modified cylinder head with revised inlet & exhaust ports for optimized gas flow
Higher compression ratio
Titanium valves & stiffer valve springs
Revised cam timing > for increased rpm
High Flow Fuel Injectors
Low inertia race kit alternator
Revised 1st and 2nd gear ratios
Race developed, adjustable slipper clutch
Magneti Marelli Race ECU
Revised engine covers for reduced width
Different sump for improved exhaust header run
