E&C Razor Chain Tensioner Spring

Tired of a lose chain that gives grief and wont stay on under heavy abuse!? US TOO! That's why we have designed this upgraded spring to work with the stock chain tensioner and provide MUCH stronger chain tension with out the need to heavily modify your bike!

Compatibility

THIS IS FOR RAZOR MX500, MX650, SX500 & RSF650 ONLY

Recommended for T8F chain upgrades, may be very stiff for stock 25h chain. Check fitment before purchase!
