Had 3 or 4 inlines. didn't like how a guy really had to wind it up for the juice, screaming around, kinda annoying. plus really had to be good on the brakes and blipping through down shifts, never got as good as i should have, which brings me to the natural engine braking of a twin, and power down low really suited me, plus center of mass and bike narrowness are nice, rsvr could lose some weight though.Heard from NUMEROUS riders, that a twin is Ideal for street. short answer.
