This chain was designed specifically motocross racing. This is a great chain for all CRF250 and CRF450 models. Non o-ring means more power gets delivered to the dirt. High performance, lightweight, and low friction in a gold chain. Excellent value.
--- This chain comes in 120 links and utilizes the D.I.D. ZJ Rivet Master link which requires a rivet press tool ---
NOTE: For some models the optional countershaft spacer may be needed for proper chain-to-engine case spacing. If your CRF model requires a narrow chain we highly recommend the DID VT2 chain.
