Well finally chewed a belt yesterday on the 13 was playin in technical sidehill situations all day long. And the belt went boom lol, 620 miles on it man they make a mess . the 12 has over 1600 miles on it changed it also was gettin a little narrow about an 1/8 inch narrower then when it was new . So i'd have to say I got good life out of it. These things do need lower gearing you can tell when your lugging it down in the tight trees burping the throttle on and off 2.1 to 1 is too high. Guess its a reverse delete or belt drive to get that though.
