Maybe people have had good experiences with their chains, but I did not. I got three rides out of it and it snapped and destroyed my rear sprocket. When i initially got it and saw the outer links were hollow (save weight, or just cheap?) i was skeptical, and now I know why. Im just happy it didnt punch through my engine case.
Mine snapped also
D.I.D all the way now
x3
Mine stretched pretty quick, came off and took out my case saver.
D.I.D. on it now also. No problems. A chain isn't a good place to cut costs, as I now know.
I had great wear life out of my stock DID and then tried a Sidewinder (what a P.O.S. !!!) I'm now running a RK and having great luck so far. I've never been brave enough to try the Primary Drive.
