used on a 09 300 xcw ktm 2 stroke

Comments On Jun 23, 2013:you get what you pay for, some stretching after 18 hours, if you don't mind a little more adjustment on the the bike because of the stretching chain, then, this is a descent chain. other chains have not needed adjustment til well over 45 hours
good average chain

good chain

Comments On Dec 14, 2007:great chain for normal riding. I run this on my DR350 and it has been great. The x-ring is the way to go for racing.
Additional Comments On Aug 17, 2011:i got 3000 + miles out of mine. i am buying another for sure.

Not worth buying

Comments On Jul 25, 2011:I bought this product and lasted me 11 hours of trail riding till an inner link broke. I was lucky to see the crack, could have been dangerous if the chain broke

ever stretching chain

Comments On Jul 28, 2011:After about 400 miles of riding on my XR650L - some moderate offroad - this chain has stretched to the point where it is quite loose around the sprockets.
I bought it because of reviews that said it was strong and didn't stretch, but that's not the case for the Big Red Pig XR650L. I'll have to get a quality o-ring for my replacement.
One plus about the chain is that it has stayed very clean because of the gaps in the inner links; no gook or mud piling on at all.
It might be the right chain for a lower torque bike.

Primary Drive Makes Excellent Chains And Sprockets

Comments On Apr 14, 2011:This may be just a regular chain but it is made very sturdy and strong.They wear exceptionally well and last a very long time.The o ring type chain i bought also was a primary drive chain and it took 2 years to stretch out and wear.Still working i just purchased this one for when the o ring chain wears out.You must maintain a chain to extend its life.If anyone tells you their chain wore out fast it was because they did not take care of it properly and keep it in adjustment.
