Description
Ring wear is one of the fastest killers of 2-stroke performance—loss of compression means loss of power, throttle response, and fuel efficiency. The Wiseco 2638CD Ring Set is precision-engineered specifically for the Honda CR250R, delivering the exact clearances and material properties needed to maintain peak cylinder pressure across your entire power band. Whether you’re rebuilding after a top-end refresh or upgrading an aging engine, these rings restore the seal integrity that separates a tired motor from one that performs like new.
