I just replaced the factory Metzelers with Avon Cobras and I really like the difference it makes. The bike handles better now. It takes turns better and it takes bumps better. My wife is often a passenger and she noticed a big difference in the ride. Another thing that I really like is that it handles road snakes much better than the Metzlers. On a 6,000 trip last year, I got to the point that I avoided road snakes, etc., with the Metzelers because they could throw the bike all over the road. The Cobras are hardly even affected by most road snake, cracks in the road, etc., so I usually just ride over them now and don't even notice them.
