Yup - and you aint heard nuffin til you get next to a motogp bike. It would sound louder than any road bike if it was a mile away Deano. They don't have cans as such. More like tuned pipes.

Seriously they are deafening even from the spectator area. Especially when they used to use the "big bang" firing order like Kawasaki did a couple of seasons ago. They fire two cylinders at the same time to try to give it the engine characteristics of a v twin.
