Valve Black Diamond™ - KIBBLEWHITE (Manufacturer's ref: 30-30633)
Designed for enduro and motocross, the Black Diamond™ valve is an engine component crafted to withstand the demands of high RPMs. CNC machined from a monobloc forging in EV8 stainless steel, it combines lightness and robustness thanks to an optimised profile for efficient exhaust flow. Each valve is modelled using finite element analysis (F.E.A.) and its profiles are validated on a computerised flow bench.
- Application: exhaust
- Head diameter: 26.00 mm (1.024")
- Tulip angle: 20°
- Construction: monobloc forged in EV8 stainless steel, CNC machining
- Surface treatment: special German process (treatment at 0.002" depth with a surface layer of 0.0002"), aimed at improving wear resistance and reducing friction, providing superior protection compared to chrome or electrolytic nickel plating
- Stem: black Nitroneg coating
- Manufacturing: United States
- Note: requires the use of a Kibblewhite spring kit
Common compatibilities: HONDA CRF 250 X (ME11) 2016-2017, HONDA CRF 250 R (ME10) 2007. Part intended for demanding modifications and replacements, suitable for riders who want a durable and controlled valve for their engine.
