I bought my 06 ST in June 2016. Immediately purchased Michelin Pilot Road 4GT's the first week, even though my bike came with new Dunlops. The rear Dunlop failed at high speed the first week of ownership. The sidewall separated from the tread on an 80 degree Sunday afternoon. I have over 14k on my Pilots. Bought new pilots today, Jan 10, 2018. What a great tire. Well worth the extra 40 or 50 dollars per tire. This is not an endorsement, just my personal experience. Special note: At 61, I ride aggressive. So, yes. I am impressed Michelin. One day, during heavy rains, I rode 100 miles at high speed. The bike responded well with these tires. I felt at ease. For me, the extra dollars are well vested for the return of handling, confidence, longevity and quality.
