1120 miles on 11 pro. Was my fault, was stuck facing up hill and tried to move it uphill in deep snow and spun it. Otherwise was still going strong. Very Happy.
i have 1400 miles on my 11 sba with the original belt still looks good and pulling the same rpms for the money they get for the 1115 belt they better last
Mine look/work fine for a long time, but lose some rpm around 600ish miles. Yes that includes adjusting deflection, cleaning etc. I'm not nice to them as I ride 2 up with my girl semi-often and still want to go all the same places.....lol
