Set of 8 high performance exhaust valves for the second generation Suzuki GSXR1100 Watercooled 1993-98.
 
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 strength and heat resistance.
 
Valves are finished with durable black nitride coating to avoid stem wear and increase durability.
These valves have hardened valve tips.
 
Race Series is our new design that improves on our previous valves, 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 27,0 mm (stock size). This size is plenty for all horsepower goals.
 
These valves are actually lighter than the stock ones by 0,6g.
