Hi this 10mm power valve spacer is made to fit Honda cr250 from years 92-01.The spacer enhances the volume of the exhaust chamber and gives you more low-end power. It was used by many pro-riders back in the day. Simple installation, just fits between the chamber cover and the chamber it self. All you need is some longer bolts.

Made from 6082 billet alloy.
