Specs At A Glance

Good To Know

Q: Will this chain fit my 1976 Yamaha DT125 without modification? A: It is sized 428 pitch and 114 links to match the stock DT125 chain run, though you should confirm your sprocket sizes and axle position before ordering. Always check the link count against your existing chain.

Q: Should I replace the sprockets at the same time? A: Replacing a chain on worn sprockets accelerates wear on both, so inspect tooth shape and replace sprockets if they are hooked or sharp. A matched chain and sprocket set lasts far longer.

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