Valve Black Diamond™ - KIBBLEWHITE (manufacturer part no. 40-40562)
Designed for demanding quads, the Black Diamond™ KibbleWhite valve is a CNC-machined intake valve made from a single-piece forging of EV8 stainless steel. Its optimised profile, developed through finite element analysis (F.E.A.) and tested on a computerised flow bench, aims to ensure a smooth intake flow and mechanical strength suitable for engine demands.
This valve is aimed at riders looking for reliable parts for the cylinder head and exhaust of a quad engine block. The material and treatments applied limit seat wear and contribute to good longevity of the distribution components without claiming unmeasured specific gains. Commonly fitted on KAWASAKI KFX 450 R (KSF450B) models 2012–2014.
