1850CS Ring Set 47.00mm for Wiseco Motorcycle Piston Rings

Ring Set for Wiseco

This 47.00mm ring set replaces the piston rings in compatible top-end rebuilds, with the 1850CS cross-reference matching the original part number.

Overview

The 1850CS ring set is a 47.00mm piston ring set made for top-end rebuilds where compression loss or oil consumption points to worn rings. This ring set re-establishes the piston-to-cylinder seal so the engine holds compression again. It suits riders and mechanics performing routine rebuild work.

• Ring set configuration for a single piston application
• Cross-references part number 1850CS for easy verification
• Steel ring construction resists heat and wear under load
• Designed for replacement during top-end service

Fits These Machines

• for machines specifying a 47.00mm bore piston
• for applications calling for the 1850CS ring set
• for engines requiring a single-piston ring replacement

On-The-Job Use

• Top-end rebuilds after compression loss
• Routine piston and ring replacement service
• Cylinder honing and re-ring jobs
• Restoring sealing after overheating or scoring

Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my piston? A: The 47.00mm bore and 1850CS number must match your piston and cylinder specification. Measure the bore and check your service manual before ordering.

Q: Can I install new rings without honing the cylinder? A: New rings seat best against a properly honed and within-spec cylinder wall. Inspect the cylinder for taper or scoring before installation.

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