The most recent owner reviews fitted in this size, in their own words.
S22 OEM mt09sp is a fab tire for fast sport riders but boy do they wear fast, I have owned bike 3 years and went through 2 rears and one front in 5000 miles the center flat spots real fast on the rear with noticeable wear after 500 miles and the front shows good tred but road camber flat spots on tire makes it a bit disappointing as you would expect the tire to wear more even another issue is wet grip they never felt capable in damp or consent rain conditions I think due to tread pattern, they can't clear water fast enough, for that point I'm not putting these back on the bike as better harder wearing black hoops out there now
Outstanding tires, never felt loosing grip both dry and wet roads. Very long mileage - 16500 km (10000 miles), half with luggage and passenger on mountain roads. Replaced with Michelin Pilot Road 4, also good tires but very noisy compare to Dunlop. Definitely the best tires I ever had on my Yamaha!
Fitted to a BIG tRIUMPH tROPHY 1200 and used "Sportingly", these bueaties have lasted well and really inspire confidence.
Bit disappointed to get 5,000 miles out of teh front and shoed significant wear on just the one side, but the rear is still measuring 5mm after 5,000 miles so can'tcomplain really.
