Triumph Motorcycles has begun testing the 765cc Street Triple engine it will supply for Moto2 from 2019, after signing a three-year deal with Dorna.
The Triumph triple will debut in June 2018 for the 2019 season but has released a video of the engine being tested on a bike on the dyno.
Just listen to that triple wail!
Moto2 test rider and 2009 125cc World Champion Julian Simon (pictured top of page) has tested the engine at the Spanish Ciudad del Motor de Aragón circuit.
Triumph says the engine is “ahead of expectations” and the bike delivered “good, consistent, and competitive lap times”.
The end of the video says “there’s even more to come in 2018″ which is a reference to further development.
It may also be an indication of an even racier street version than the flagship Street Triple RS which produces 90kW of power at 11,700rpm, up 16%, and 13% more torque at 77Nm @ 10,800rpm.
MBW reviews the Street Triple RSAs part of the development of the engines, they are expected to be used in the CEV Moto2 European Championships from next year.
Honda has powered the MotoGP feeder category with its 600cc engine since it began in 2010 when it replaced the 250cc two-stroke class.
Triumph Daytona 675R engines have powered super sports wins at the Isle of Man TT, Daytona 200 and British Supersports Championships in 2014 and 2015.
But the new engine is a significant upgrade.
The Daytona-derived 765cc Street Triple engine has more than 80 new parts including an increased bore and stroke, new crank, pistons, titanium valves and stiffer springs, and Nikasil-plated aluminium barrels.
It will also have a taller first gear ratio, a tunable slipper clutch, a new sump and an ECU developed by the supplier of MotoGP’s control unit Magneti Marelli.
