Ouch! Guys play nice!!! I liked the Bridgestones, but I enjoy the better feed back of the Pirrelli's. I am low on cash so I was trying to keep a low budget approach to improving the busa. I usually run 30-32psi when pushing the bike at the track or the dragon! I had good results with the stock tire, but there are better choices to be had. I didn't want to mix brands and compound, so the reason of going with the BT015 or a BT016 for thr rear and add the spocket while I am there. I am looking at trying to raise the rear end some for more front end feel, in which I feel it is lacking! Any other smart low budget ideas are welcomed!
