Specs At A Glance

Good To Know

Q: Does this chain fit both the 1983 and 1984 IT490? A: Yes, it is listed for the Yamaha IT490 spanning those model years, though you should verify your sprocket sizes and chain length before ordering.

Q: Should I replace the sprockets at the same time? A: Replacing the front and rear sprockets with a new chain is common practice because worn sprockets accelerate wear on a fresh chain.

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