Again thanks for the responses.
In hindsight I agree, problably target fixation. Mixed in with lack of experience.
I've been commuting on the Bandit since Feb'05, and already done 12K miles. That's right 12K

. Use it for everything including 60miles-a-day commute.
On the SV I've only done 350 miles. Probably take a bit more miles to get used to the differrent riding style.
