Wiseco 47mm Piston Ring Set for Honda CRF70F 2004-2012 1850XE

Worn or damaged piston rings directly compromise combustion chamber sealing, leading to blow-by, power loss, and increased oil consumption. The Wiseco 1850XE ring set restores proper ring-to-wall contact, ensuring optimal compression and reliable performance across the full operating range of your Honda CRF70F. This is essential maintenance for any engine rebuild or high-mileage restoration.

Wiseco engineered this ring set with precision tolerances and high-grade materials to withstand the thermal cycling and pressure spikes common in small-displacement four-stroke engines. Each ring is individually honed to spec, guaranteeing consistent fit and sealing without gaps or rocking. Installation is straightforward—these rings are a direct bolt-on replacement when paired with a compatible Wiseco piston.
