i dont own a bike of my own but i have been rideing my dads bikes for about 3 years now. i learened on a GSX1100G (basicly the older version of the bandit) and he recently bought a 03 SV650S it dosent have the power of some of those inline fours but i like the sound of it.
My brother is riding a 2004 suzuki SV650S, and he is loving it. Ive riden it several times and shes a good bike, not much left after about 220km/h, but she gets there in a hurry.
dude, tell your brother to put a new pipe on it, we got a M4 for ours and it makes it sound great! really gives you the full sound of the V twin.
