Have been using BT020s on the ZX10, but the guy at the bikeshop recommended some Pirrelli something-or-other sports/sports-touring tires. I never realised how much difference a set of tires could make. The turn in is soooooooooo much sharper. On another topic, suspension setup. I'm too lazy to google, but, what effect do the various suspension adjustments one can do make. Ie; preload, high/low speed rebound and compression damping, etc. Also, what effect will a heavier fork oil have compared to a lighter one? And finally, a friend asked me on the weekend, and I had a vauge idea, but not really a good one. How do gold-valves work?
