Good To Know

Q: Do I need to replace the guide and stopper together? A: Both parts wear against the timing chain, so replacing them as a set during a chain service is the common practice. Inspect the chain and tensioner body at the same time for wear.

Q: Is this an original Yamaha part? A: This is an aftermarket timing chain tensioner guide and stopper made for Yamaha YFZ-R 450 machines. Confirm your model year and engine details before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
