CRF450R1.220 EXH VALVE

Black Diamond™ valves are CNC machined from one-piece forgings of EV8 Stainless Steel

Lightweight, strong, one piece forging with profiles that provide excellent flow characteristics

Valve is infused by a special German process to a depth of .002, with a surface build up of .0002 which improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating

Each valve is designed using Finite Element Analysis (F.E.A) software, and profiles are tested on a computerized flow bench

Stems are coated with black nitroneg

Made in the USA

Requires the use of Kibblewhite spring kit.
