With the thread on when to move up I had another question. How do u decide what and when to upgrade parts. Now I myself am nowhere near outriding my stock cbr but some of u guys probably are. How did u make the decision on what parts and when. I know there are some safety related ones like steering dampers but what prompted you to drop $1000 on new suspension when the stock stuff wasn't broken. I'm in the market for a dedicated track bike and wondered what some of the pros put in order of importance, value, and just why when the bikes perform phenomenally out the box. How do u know when u need that little bit extra the aftermarket provides.
