Triumph Motorcycles and Dorna, the commercial rights holder of MotoGP, has signed a three-year deal to supply race tuned 765cc three-cylinder engine by Triumph, for the Moto 2 world championship from 2019. The engine is said to be a significant development of the 675R engine.
The race Specification Triumph engine is based on the powerplant that fuels the 2017 Triumph Street Triple RS, has been modified further to allow the engine to breath more freely than the production bike, increasing the overall performance. Other changes that have been made specifically to use the engine for racing purpose.
Various modifications are done to obtain the race specifications:
- 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
- Tuneable race developed slipper clutch
- Specific race ECU; which will be developed with Magneti Marelli
- Revised engine covers for reduced width
- Different sump to allow for improved header run
Dorna had been courting other manufacturers to take over Honda’s role as Moto2 engine supplier, with the previous front-runner being Italian boutique brand MV Agusta with its 675cc three-cylinder engine powering an extensive middleweight lineup. But the storied Italian marque has been plagued by financial difficulties in recent years, making the partnership an unfeasible scenario. Interestingly, Triumph has been concentrating its new model efforts for the past five years on the growing classic/retro and adventure-tour markets, and sales of the once-proud Daytona 675 three-cylinder-powered sportbike have sunk to the point that rumours have been rampant of it soon being dropped from the lineup. Triumph factory management have been careful to avoid spending major dollars on any racing effort, and their road racing involvement has literally vanished. So the agreement to become the Moto2 engine supplier has been a surprising development to many in the racing world.
Becoming the Moto2 engine supplier is not easy. The engines will have to be reliable as a rock, something the Daytona 675 engine hasn’t been known for, during its racing tenure compared to others, although if the 765cc engine will be used, it is reportedly an all-new design. Meanwhile, the Honda CBR600RR engine proved to be nearly bulletproof, with ExternPro, the Moto2 engine preparation firm since 2013, claiming that there have only been five engine failures in “a million kilometers.”
The chief commercial officer, Paul Stroud, said that this is a significant moment for Triumph that brings a whole new chapter to the companies racing history. The Chief Executive officer of Dorna, Carmelo Ezpeleta added that Triumph engines are renowned for their strong, linear power and torque delivery and have achieved many successes on the track making them the best choice for the Moto 2 Championship. He also said the company is looking forward to the 2019 season and the beginning of a new generation of Moto 2 in partnership with Triumph.
