First bike eh? I have read loads on what would be an appropriate first bike and the overwhelming view is that a litre is too much too handle, but I tend to take the view that it will only go as fast as you make it so what is the problem?
Anyway as for gas mileage, I havent really monitored it that closely yet so no figures but I am expecting about 35 to the gallon which over here in mother England is about 12 to 13 pence per mile now we have gone through the £5 per gallon threshold (just over 10 Canadian dollars)
I just love where the pwer is on this, no low down power on the ZX6R but with this it's all the way through the mid to upper range.
Take it easy
