Wiseco 71.25mm Ring Set

This is a Wiseco 71.25mm piston ring set, designed to work with Wiseco pistons for your 1981-1984 Honda ATC250R. Piston rings are crucial for a few key jobs: they create a seal between the piston and cylinder wall to maintain compression, they help control oil by scraping excess lubricant off the cylinder walls, and they transfer heat from the piston to the cylinder wall. When you're rebuilding an engine, especially for performance, the right rings are essential for getting the most out of your piston and cylinder setup.

Wiseco develops these rings specifically to match their pistons, aiming for optimal sealing and performance. They test and validate the ring designs and materials to ensure they hold up under demanding conditions, whether you're looking for race-ready performance or just a solid rebuild. This set is for a 71.25mm bore size, which is a specific measurement you'll need to match to your piston and cylinder for a proper fit.
