Overview

This 520-116 O-ring drive chain delivers reliable power transfer for the 1984 and 1987 Suzuki RM125.

Specs At A Glance

Good To Know

Q: Does an O-ring chain need regular lubrication? A: Yes. The O-rings seal grease inside the rollers, but the outer plates and sprocket contact points still need periodic lubricant to control wear. Clean and lube the chain after wet or dusty rides.

Q: Will a 116 link chain fit both the 1984 and 1987 RM125? A: A 116 link 520 chain matches the stock length called out for these model years, but sprocket size changes can alter the needed length. Verify your setup before ordering.

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