1850XE Ring Set 47.00mm for Wiseco Motorcycle Piston Rings

Ring Set for Wiseco

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

Overview

The 1850XE ring set is a 47.00mm piston ring set built for top-end rebuilds where worn rings cause compression loss or blow-by. This ring set restores the seal between piston and cylinder so the engine holds compression again. It is made for riders and mechanics handling routine rebuilds rather than full engine replacement.

• Ring set configuration for a single piston application
• Cross-references part number 1850XE for easy verification

• for engines requiring a single-piston ring replacement

On-The-Job Use

Good To Know

Q: How do I know this ring set matches my piston? A: The 47.00mm bore and 1850XE 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.
