Great Value
I have used Primary Drive chains and sprockets on many bikes now. Have found good fitment although there has been some models with clearance issues on the countershaft sprocket as the PD chain seems to be a bit wider than other brands. An easy fix is to install a shim washer behind the counter shaft sprocket. As always with any chain install, a person should check clearance between chain and engine case. Great chain and sprockets for the price.

Chain not correct.
Chain way to long for my 2018 KTM 250 XCW. Havent measured yet but 3 or 4 links too long. Ordered because I dont have the ability to cut or break a chain so wanted something that would be right from the start.

Had some doubts, because of the low price! BUT A FIRM BELIEVER NOW! VERY STRONG!!I TRAIL RIDE AND HIT THE TRACK!
Very strong! I could feel the difference between the stock sprockets and chain and the primary drive parts! I really noticed on launching from a jump ,no outright chain slap, while lugging the motor you don't get that annoying chatter type sound!! Love this SET! I will be buying this recipe for my old XR TOO!!! P.S. NEED TO USE THE FAST TRACK 1MM SPACER ON COUNTER SHAFT SPROCKET! VIA CHAIN IS WIDER! WORKS PERFECTLY!!

What ratio would be best I'm 180 lb woods Rider on kx 125?
Ronald G on Oct 3, 2018
