Good To Know

Q: What is the advantage of an O-ring chain? A: O-ring seals keep factory lubricant inside the chain and keep dirt out, which slows wear compared to a standard chain. That matters most in muddy or dusty off-road conditions.

Q: Will this chain fit a 2025 YZ125X without cutting? A: It is sized at 114 links to match the stock length on 2020 to 2025 models, so trimming is usually unnecessary. Always verify against your sprocket sizes before fitting.

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