PERFECT

Comments On Mar 02, 2014:Bought a used 2000 400EX. The chain and sprockets were so worn I couldn't adjust the over amount of slack out. This kit was exactly what I needed. Perfect fit. Install was a breeze. High quality without the high price tag. Will buy again if the need ever arises.

Good

Comments On Feb 20, 2014:It's a chain. I don't have much to say. It fits good and it looks good. If it lasts as long as my stock chain I will be in good shape.

Great value for the money

Comments On Jan 15, 2014:450 4 strokes are hard on drivetrain parts, no doubt about it, this kit represents good value in a complete set of sprockets and chain, note that these o ring chains are wider than most, make sure to check case clearance when installing, you might need to shim the countershaft sprocket out a bit. The Master link is a clip style however there are dimples on the ends of the pins, can we rivet these master links too?? Also I like to have spare master links but I can't find them on the site, can they be ordered?? its a "Primary Drive" 520 O ring master link whats the part number...anyone??
TECH NOTE: The master link for the chain is Part# 1021270020
