Valve Black Diamond™ - KIBBLEWHITE (Manufacturer Ref: 30-31166)
Black Diamond™ exhaust valve designed for demanding motocross engines. CNC machined from a monobloc forging in EV8 stainless steel, it combines lightweight and rigidity for reliable performance at high revs. The tulip profiles have been modelled using finite element analysis (F.E.A.) and validated on a computerised flow bench, ensuring optimised gas flow for discerning engineers and tuners.
Designed for modifications and replacements on machines such as the HONDA CRF 250 R (2008-2009), this Black Diamond™ valve is aimed at riders and mechanics seeking a high-precision machined engine part, suited to the demands of motocross.
