Another great Acerbis product!

This is definitely the best chain guide out there for the price. Only have a few hours on it but seems like better quality than stock on my yz250.

Didn’t Fit

This was supposed to fit my YZ250F but would not fit in the OEM aluminum support bracket.

May want trim the area in which the sprocket passes by to prevent rubbing the anodizing off of sprocket. This product will last over a 100 hours of ride time.

Solid replacement for a over-priced oem wear item

Standard factory fit. Way cheaper compared to OEM. Acerbis is renowned for its plastics,and I expect no less from this block.

Ok product

Well made. Grooves were straight. Very thick and slippery rubber. Easy to install. Good price compared to OEM. Held up to its first abusive ride.

A: These chain guide black replace the stock block but still retain the stock housing. It is not a complete rear chain guide. The material is not rubber but more of a durable plastic.
Over 6 years ago
A: It's all urethane. The idea is to let the chain slide through. Rubber would grab the chain too much and wear out too quickly.
