I have had one set on my 99RSV. When they were new they were great. I fount my self pushing the bike harder in and out of curves.It was fun for a while. After about 2K miles I started getting frount end vibrations in sharp curves. After 10K miles they still had 1/2 the tread . But they were vibrating stuff loose on the bike. The rear tire had 4 large cracks come down in the groves of the tread. After removing the tires they were as hard as a rock. I ? Metz about all of these problems with no luck. The best reply I got back was these tires were made for lighter sports bikes. Like i said they stuck like glue when new. I would not buy another set for a large bike. How ever the tread would have probley gone 15K.
