Posted November 27, 20186 yr https://ultimatemotorcycling.com/2018/11/26/triumph-moto2-triple-race-engine-horsepower-unveiled/ 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. “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 Edited November 27, 20186 yr by r1limited “Laws that forbid the carrying of arms disarm only those who are neither inclined nor determined to commit crimes.” --Thomas Jefferson quoting Cesare Beccaria
