It was recently announced that the Moto2™ class engine supplier from 2019 will be British marque Triumph - so here's everything you need to know about the engine following the announcement. Based on the highest specification 765cc powerplant from the Street Triple RS, the engine has been developed for Moto2™ 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 Moto2™ 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.
Trevor Morris, Technical Director from ExternPro, responsible for the final preparation of the engines for the race series:: “It is incredibly exciting to be working in conjunction with the iconic Triumph motorcycle company in supplying engines for the Moto2T 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.”
Julian Simon, 2009 125cc World Champion and Moto2™ runner-up and experienced Moto2™ test rider, who has been involved with the engine development testing at Aragon: “The engine feels strong and in particular the mid-range is very impressive. The feel between the throttle and the rear wheel is very direct and controllable. The general feeling is very good and the engine already shows great potential.”
