525-108 O-Ring Drive Chain for Yamaha YZF-R7

This 525-108 O-Ring Drive Chain is a replacement drive chain built for the Yamaha YZF-R7, delivering reliable power transfer from the countershaft sprocket to the rear wheel.

Overview

The 525-108 O-Ring Drive Chain is a direct-fit replacement chain sized for the Yamaha YZF-R7 across the 2022 through 2024 model years. It uses O-ring seals to hold lubricant at the pins and rollers, cutting friction and stretching so the chain stays in adjustment longer. This 525-108 O-Ring Drive Chain suits riders replacing a worn or stretched original chain, whether for routine maintenance or a full drivetrain refresh.

Specs At A Glance

Good To Know

Q: Should the sprockets be replaced at the same time? A: Worn sprockets accelerate wear on a new chain, so replacing both together is the usual practice when either shows hooked or uneven teeth. Q: Does this chain arrive pre-stretched? A: It is pre-stretched to limit initial elongation, but checking and adjusting tension after the first rides is still recommended.

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