the me880's I put on my bike rear did 32500 or thereabouts front is still on at just over 40000 ks. Been all over on it including towing a trailer for many kk's. I also put the old girl through her paces around barbagallo race track as hard as i could. Ridden in some shockin weather no sign of scarey slips. If you ride for longevity get em you wont get better - but if you are dragging your hero pegs go for something softer and forget about long ks. Col
