Video: Triumph tease sound of new Moto2 engine

British firm have released our first listen to what will become the sound of the Moto2 class from 2019, as their new 765cc triple engine took to the track for testing last weekend at Aragon. Running in a modified Daytona 675 chassis and at the hands of former 125GP world champion Julian Simon, the new motor is set to bring a very different sound to the middleweight class as it switches from the inline-four Honda CBR600 engines it has used since its creation in 2010.
