Great chain!

over 40K miles on a race modified ZX6RR. I've had my bike going 150 MPH for 10 miles on the streets of Michigan (it was a life/death emergency, my dad was killed in a car crash needed to get there ASAP to provide medical Autorization) and never had any issues. Chain is as smooth at 55mph as it is at 150mph. Even after 40k rough/hard miles my chain is still way below max strech (21 links should be 12.5 to 12.7 inches, center of post to center post with 20lbs of weight at around the middle of measurement area). My factory service manual recommends checking several sections, not just one as chain wear is not always even. I use DuPont Teflon Chain Saver and have had really good luck with it and it's wax based so it doesn't sling all over like oil based chain lube. Lube this RK every 250miles and it'll last many many years and many miles. Will be buying this exact chain when/if this one ever stretches...

I am very pleased with this chain. I went on a 4 hour ride and the chain did not stretch and did not need to be adjusted for the second ride (Used on CR500). It comes with a Rivet master link.

Great Chain!

Bought this for my Kawasaki Versys used the 114 link chain with stock front sunstar 15 tooth and a rear sunstar 44 tooth in the back. What a difference in RPM's and the smoothness of the bike! The chain came with a press on clip so you will have to get the clip connecting link Part # 119997 and its a pain to get on with out a link pressing tool. I used a small C Clamp and pressed the sides of the links together to get the clip on.! I will order that tool next time!

Great chain

Chain had excellent fit and finish. Anyone needing a rivet link, mine came with it, not the clip type as stated.
