I can understand why my bike under-steers off road; it isn't meant to be ridden off road.
However I noticed it seemed worse after replacing the Rally GP with the Supercycle (in lieu of buying new drive train since I had this old bike lying around).
Also, it's under-steering on dry pavement! I have had enough road rash to not want any more, and this is getting a little disconcerting. The back was even sliding a bit the other day.
Is it the steering geometry or the tires? I'm guessing tires.
I enjoy high speed cornering at severe lean angles, and the thought of a high side keeps intruding, and I'm wondering how many more miles 'till I have to start worrying about a blow out?
