I've been getting a lot of wheel spin from my Classic since I've put the CF rims on it. Even though the tires look new, they are about 8 years old, and I guess the rubber is hard. I've been playing with it and it's getting really fun. A couple of friends and I were leaving a bar a couple of weeks ago. I got out first and once I was straight jumped on the throttle, causing the rear tire to spin and drift right. Well the road turns right, so I leaned right as I caught 2nd, and the rear drifted left through the turn. Once the road was fairly straight, I grabbed 3rd and shifted my weight back and forth a couple of times, making the rear do a right left right left dance until the tire stopped spinning somewhere toward the end of 3rd. They couldn't stop talking about it for a week after. One said I knew it had power, but that's way more than I'd ever want in a bike. I smiled and said, just remember that's my slow one.
