The RK M420 Standard Drive Chain is engineered for dependable power transmission in compatible motorcycles, powersports vehicles, and other applications using an M420 chain system. This chain includes 112 links and is manufactured from heat-treated medium carbon alloy steel for strength, durability, and consistent performance. RK is recognized for producing reliable drivetrain components designed to withstand demanding operating conditions.
Every component of the RK M420 chain is heat-treated and shot-peened to improve resistance to wear, fatigue, and repeated loading. Four-point pin riveting helps secure the chain assembly, while solid rollers support smooth engagement with compatible sprockets. The included clip connecting link simplifies installation and allows the chain to be serviced using suitable tools and proper maintenance procedures.
Fitment: Designed for vehicles and equipment requiring an M420 standard chain with 112 links. Confirm the vehicle model, sprocket specifications, chain size, and required link count before installation. The RK M420-112 is a suitable replacement for compatible original-equipment or aftermarket drive chains, but fitment should be verified against the manufacturer’s application requirements.
Use appropriate chain lubricant and maintain correct tension according to the vehicle or equipment manufacturer’s recommendations. Proper alignment, lubrication, and inspection can help extend service life and preserve smooth drivetrain operation. The RK brand and manufacturer part number M420-112 provide clear identification when selecting a replacement chain for compatible applications.
