MotoGP has just announced that Triumph has signed a three-year contract with Dorna, the commercial rights holder of MotoGP, to supply a dedicated race-tuned 765cc Triumph triple engine based on the powerplant from the all-new 2017 Triumph Street Triple.

Paul Stroud, Chief Commercial Officer for Triumph Motorcycles, said: “This is a significant moment for Triumph that brings an exciting new chapter to our 110-year racing history and builds on our celebrated TT and Supersport race winning triple engines. We look forward to a long and thrilling relationship with Dorna and the Moto2 teams, riders and fans.”

The new engine is a significant development of the race-winning Daytona 675R powerplant that has powered Supersport wins at the Isle of Man TT, Daytona 200 and British Supersport Championships in 2014 and 2015.   Based on the highest specification 765cc powerplant from the Street Triple RS, it has been developed for Moto2 with the following modifications:

  • Modified cylinder head with revised inlet and exhaust ports for optimized gas flow
  • Titanium valves and stiffer valve springs for increased rpm
  • Low output race kit alternator for reduced inertia
  • Taller 1st gear ratio
  • Tuneable race-developed slipper clutch
  • Specific race ECU
  • Revised engine covers for reduced width
  • Different sump to allow for improved header run

Trevor Morris, Technical Director from ExternPro, who will be responsible for the final preparation of the engines for the race series, commented: “It is incredibly exciting to be working in conjunction with the iconic Triumph motorcycle company in supplying engines for the Moto2 World Championship. I have been a fan of the triple engine for a long time, its unique characteristics and performance will ensure and enhance the future success of the championship.”

The race-spec Triumph 765cc Moto2 engine has been developed further to allow the engine to breathe more freely and rev harder than the production bike, increasing overall performance. Other changes have been made specifically to adapt the engine for race use.
