Good chain for the money
Good chain for the money, It seems to stretch pretty quick, I can get about 15-20 hrs out of it, and I oil it every time he comes of the track.

So-so
Chain came well lubed as others stated. However, this chain did not come with a master link. I searched here on RM and several motorcycle shops and lawn/garden shops to find correct one to no avail. Ended up taking a link and a half out of original chain on a '03 KTM 50 to get the boy back on track. Would suggest other chain that comes with master link.

There are better
Don't get me wrong, I have used probrably a couple dozen of these chains. If they go on sale, I will pick one up here and there. There are stronger and more durable chains out there for the same money though.

Good chain for the money
Have ran pro taper for years. For the money they hold up well. We get about half a race season out of a set of chains and sprockets. Stretch is marginal just don't tighten and it will last. Keep it clean and lubed.

Does this chain fit any bike?
preston r on Nov 3, 2018
BEST ANSWER: If you get the right size it will. 420 is usually a 110cc or less with exception of the crf150r. A 428 is usually the chain used for 85cc/105cc 2 strokes. Then 520 for the big bikes. Find out what chain is right by going to the parts finder or the OEM diagram.
Does this come with a master link?
Keelan G on Dec 16, 2017
BEST ANSWER: Yes it does. This chain is the best
