Triumph has signed a three-year contract with Dorna – the commercial rights holder of MotoGPTM – to supply a dedicated race tuned 765cc Triumph triple engine, based on the powerplant from the all-new 2017 Triumph Street Triple.
The new engine is a significant development of the race-winning Daytona 675R powerplant that has powered supersports wins at the Isle of Man TT, Daytona 200 and British Supersports Championships in 2014 and 2015.
Based on the highest specification 765cc powerplant from the Street Triple RS it has been developed for Moto2TM with the following modifications;
- Modified cylinder head with revised inlet and exhaust ports for optimised gas flow
- Titanium valves and stiffer valve springs for increased rpm
- Low Output race kit alternator for reduced inertia
- Taller 1st gear ratio
- Race developed slipper clutch which will be tuneable
- Specific race ECU; which will be developed with Magneti Marelli
- Revised engine covers for reduced width
- Different sump to allow for improved header run
Based on the new 2017 Street Triple powerplant, the Triumph Moto2TM 765cc triple engine has been developed and tuned for a major step up in power and torque.
In ‘road’ set-up the new 765cc engine delivers the highest ever level of performance for a Street Triple; delivering power of 123PS @ 11,700rpm and 77Nm Torque@10,800rpm.
It has more than 80 new parts compared to the previous generation engine, including an increase to the bore and stroke. All-new engine components include;
- new crank
- new pistons
- new con-rods and balancer shaft
- Nikasil plated aluminium barrels
- Revised gearbox
The race specification 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.
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 Supersports race winning triple engines.
