I ride a 94' ZX1100 Ninja almost everyday. I have found for my sport bike these Q3's are about the best I have found. Cornering up in Angeles Crest Hwy. or ripping through the snake in Malibu they feel like they are glued to the road. They also heat up very quickly. I usually get between 7-8k out of them. I am not doing burn outs but I am doing hard braking, acceleration, and cornering. I keep them inflated for daily driving at max psi then drop a couple pounds for the tight corner days. At speed they are rock solid. Excellent response of traction under hard braking setting up for a deep corner. I gave them a four star for tread wear but for a super tacky and great confidence builder what can expect on tread wear. I have been in rain a handful of times and they have excellent wet grip as well. This is my third set and the first turn I dipped into I could easy feel the difference in feedback. If you have a heavier sport bike I would give these a shot....great price too.
I have been using these tires for over 90,000 miles. Always happy with how they adapt to all kinds of weather. Great traction in the rain as well as extreme desert heat. Usually get over 10,000 miles on the front tire.
I have put over 120,000 miles on my 09' 250r, and I had tried every brand I could from perelli to shinko, Bridgestone has made me the happiest in corners straights wind and rain cold and hot. This tire has, by far, the softest sidewall I've experienced??. I can't seam to find a happy pressure to get stability and traction. I am also a mechanic so I feel like maybe I should know what I'm doing here. Alas, I got the tire on the cheap for Christmas so I'll wear it out and I never put another Dunlop on my lil AlleyFighter!
