Set of 8 high performance exhaust valves for the Honda CB750F, CB900F Boldor, CB1100F and CB1100R air cooled engines. Same valves may work in the Honda CBX. Great valves for classic racing, endurance racing engines or tuff street engines.

Made of the best grade stainless steel (EV8 / 21-4N) commonly used in all high performance valves used for racing or high strung engines (N/A, turbo or nitrous), these are a great improvement over the standard valves not only in flow but also in strenght and heat resistance.

Valves are finished with durable black nitride coating to avoid stem wear and increase durability. All valves have hardened valve tips.

These valves are 23,5mm (1,0mm oversize).

These valves were designed to work with the original valve seat requiring only  usual valve seat machining.

Oversize valves are a great way of increasing cylinder head flow for modified and big bore engines.

Oversize intake valves also available
