Rode mine to work today, 103 miles round trip across country, lovely day, addictive noise, sport mode fantastic. The best bit was it didn't go bang
No, its a twin, 90' cylinder set up so it probably goes something like puff and suck, suck and squeeze, squeeze & bang, bang and bang puff.
Can't wait for fuel cell bikes to come along. Wonder what one of those sounds like as it eats itself?
