Good chain

Comments On Mar 16, 2014:Only reason it's not a 5 is I had to order a 48t rear sprocket to make it work. I ordered the kit and with 14-50 the chain was too tight not allowing the guide to have the bottom bolt. I emailed RM and they sent me a longer chain no questions asked. This caused it to be too loose at the end of adjustment. I then ordered a 48t rear and the original chain works good.
So if ordering the kit......get a 48t rear.

Hasn't snapped

Comments On Jan 27, 2014:This chain hasn't let me down on a pit bike hauling a 165 lb adult around, and I ride it up some big hills pinned. Only chain I use on my pit bike.

No Issues

Comments On Sep 23, 2013:Chain went on bike fine with new front and rear sprockets. My son rides motocross with his bike and the chain has held up fine through the season without any issues.
