ProX Piston Kit for Suzuki RM85, 47.94 mm (01.3122.A)

The PROX 01.3122.A Piston Kit is designed as an OEM replacement for Suzuki RM85 applications. Manufactured in Japan, this kit is engineered to provide dependable fitment, consistent performance, and durable service for motorcycle engine rebuilds and top-end maintenance. The 47.94 mm piston is manufactured to meet or exceed OEM specifications for reliable replacement performance.
The piston is cast from a high-silicon-content aluminum alloy that supports strength, thermal stability, and wear resistance under demanding engine conditions. CNC machining brings the piston to extremely close tolerances, helping promote accurate fitment and smooth operation when installed with properly prepared engine components. The included components are selected to support a complete piston replacement rather than requiring separate sourcing of essential installation parts.
Each PROX 01.3122.A kit includes the piston, ring kit, wrist pin, and circlips. Confirm application details and service requirements before installation, and follow the motorcycle manufacturer's procedures for inspection, clearance verification, break-in, and assembly. This replacement kit is a practical choice for rebuilding the top end of a Suzuki RM85 with components manufactured for precise, dependable service.
