Valve Black Diamond™ (Manufacturer part number: 90-9035) by KIBBLEWHITE — machined intake valve for demanding engines. Made from EV8 stainless steel, this forged and CNC machined one-piece valve combines strength and lightness to withstand the stresses of the cylinder head while maintaining an optimised gas flow profile. The profiles are validated by finite element analysis (F.E.A.) and tested on a computerised flow bench.
Ideal for Trail/Adventure, Enduro, Roadster, and Touring universes, this valve is aimed at mechanics and riders who pay attention to the quality of parts that exude reliability. Examples of applications: BMW R 100 RT Classic, BMW R 100 R Roadster Classic, BMW R 100 R Mystic (1995 models, 1000 cc). Replace your valves with components designed to last and facilitate the adjustment and maintenance of the cylinder head.
