Set of 8 high performance oversize intake valves (+1mm) for the Honda CBR 600 RR (2007-2022).
 
Made of the best grade stainless steel (EV8 / 21-4N) commonly found in high performance valves used for racing or modified engines (N/A, turbo or nitrous), these are a great improvement over the standard valves in  airflow, strength and heat resistance.
 
These valves are finished with a durable black nitride coating to avoid stem wear and increase durability. These valves also have hardened valve tips.
 
Race Series is our new design with a 30º Back Cut to improve airflow and smooth the transition to the seat area as well as other improvements aimed at saving weight by optimizing valve dimensions.
 
These valves are 28,5 mm (1mm oversize) and also have a flat face - just like the original valves. They fit in the original valve seat.
 
We also have stock intake valves and stock exhaust valves for this model. See our other listings.
