Wah, damn serious...i always thot busa acceleration is fast liao, never know in comparison to the 1 litre bikes busa is actually "slow" ...guess i am out of touch as i m a come back biker having stop for 10yrs...Then again, i can still derives great satisfaction when manipulating the fat lady around bents. My point is, i feel busa brings balance to power and comfort, which is more than i can say for those race replicas. My only gripe is no main stand for GEN2, which makes it a real pain as a sport tourer...
