Supertech Honda CRF250R 26x4.97 (+0.5mm)x84.23mm (+1mm) Flat Face Titanium Exhaust Valve - Single

This listing is for a single Supertech flat face titanium exhaust valve. It measures 26mm in face diameter, which is 0.5mm larger than stock, and has a total length of 84.23mm, which is 1mm longer than stock. The titanium construction makes this valve lighter and more resistant to heat than a comparable steel valve.

Using a larger diameter valve can help improve airflow into the cylinder, and the increased length might be useful for certain cylinder head modifications. Titanium is a strong material that holds up well to the high temperatures and stresses found in an exhaust valve. This part is a direct replacement for the stock exhaust valve on your Honda CRF250R, but it's always a good idea to check your service manual for specific installation procedures and any other components you might need.
