Specs At A Glance

Good To Know

Q: How often should I replace the drive chain on my YZ80? A: Replace it when the chain no longer meets the manufacturer's slack spec after adjustment or shows kinked links. Pairing a new chain with fresh sprockets reduces wear on both.

Q: Does this chain come pre-lubricated? A: It arrives with a factory-applied protective lubricant, but you should still lubricate it after installation and after every ride in wet or dusty conditions.

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