I have gone through 3 sets of these on my Suzuki SV650S. I commute 110 miles 5 days/week plus other riding in Southern California. I can usually get a solid years riding out of these, approx 10K-12K miles out of these tires. The front usually lasts me 12K and the rear 10K miles. The only time I don't feel confident on these tires is when I start to wear the tread too thin, otherwise I can ride aggressively or cruise the freeways with no worries. They handle great well into the triple digits as well. I've never had a single problem with these, and I highly recommend them to anyone who needs long lasting tires for commuting but still wants performance. The best of both worlds.
