Regina Chain and Sprocket Kit for Suzuki DR-Z400SM 2005-2020 (KS121)

The Regina KS121 Chain and Sprocket Kit is a convenient replacement drivetrain solution for Suzuki DR-Z400SM motorcycles from 2005 through 2020. Each kit includes a heat-treated front sprocket, an induction-hardened rear sprocket, and a precut Regina chain, helping dealers and riders complete installation with matched components from one package. The sprockets use OEM gearing to help maintain the motorcycle’s intended performance and fitment.
The included chain comes from Regina’s high-performance Z-ring series and features gold outer plates with Z44 sealing rings. This sealing design helps retain lubricant inside the chain joints while limiting the entry of dirt and moisture, supporting smooth operation, improved wear life, and dependable performance during regular riding. The gold finish also provides a distinctive appearance while maintaining the chain’s functional durability.
Both sprockets are manufactured from high-quality steel for strength and reliable service under normal drivetrain loads. The heat-treated front sprocket and induction-hardened rear sprocket are designed to resist wear and complement the included chain for balanced replacement performance. The kit includes rivet-type master links, providing a secure connection when installed with the appropriate tools and procedures.
Designed specifically for the Suzuki DR-Z400SM model range, the Regina KS121 kit helps simplify chain and sprocket replacement by combining essential components in a ready-to-install package. Verify motorcycle year, model, and manufacturer specifications before installation, and follow proper chain tension, alignment, lubrication, and rivet-link installation procedures for best results.
