Specs At A Glance

Good To Know

Q: How do I know when the chain on my TY80 needs replacing? A: Replace it when the chain can be pulled away from the rear sprocket or exceeds the factory slack spec after adjustment. Worn chains also cause uneven sprocket wear.

Q: Can I install this chain with my existing sprockets? A: Yes, if the sprockets still show even tooth wear and no hooked profiles. Installing a new chain on badly worn sprockets accelerates wear on the new chain.

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