Specs At A Glance

Good To Know

Q: Does this chain come with a master link? A: Yes, a master link is supplied so the chain can be fitted without special riveting tools in most cases. Confirm the link style matches your SRX250 sprocket setup before installation.

Q: Should I replace the sprockets at the same time? A: Replacing chain and sprockets together is standard practice, since worn sprockets accelerate wear on a new chain. Inspect both sprockets for hooked or uneven teeth first.

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