Pro Circuit Carbon Fiber Chain Guide

Reduce Chain Derailment for 2018 and 2019 KX250F/KX450F Models


CORONA, CA - July 12, 2019 - Chain derailment can end your race or practice session pretty quickly, so why not invest in a product that reduces the likelihood of your bike being pushed off the track? Now available for 2018-2019 KX250F, 2018 KX450F and 2019 KX450 models, the Pro Circuit Carbon Fiber Chain Guide reduces the possibility of chain derailment, is durable and offers a stylish look.

The chain guide includes a carbon fiber bracket as well as a block insert. The bracket extends farther towards the rear wheel than an OEM bracket, allowing for a precise feed of the chain directly from the guide to the sprocket. The block insert is CNC-machined from high-density polyethylene, providing a durable, long wearing and low friction surface for the chain to ride. The insert fits tightly within the bracket and wraps around the front face to provide wear protection. The insert can be purchased on its own as a replacement if needed.

The Pro Circuit Carbon Fiber Chain Guide is a must-have item for 2018-2019 KX250F/KX450F racers or recreational riders.
