Good To Know

Q: Does this chain come with a master link? A: A connecting link is typically included so the chain can be installed without special tools beyond a chain breaker. Confirm the listing contents before ordering if a specific link style is required.

Q: How often should the chain be adjusted? A: Check slack regularly and adjust to the tension listed in the service manual for the XT660R. Keeping it clean and lubricated extends the life of both the chain and the sprockets.

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