DescriptionKibble White Black Diamond Exhaust valve
Valve Black Diamond™ by KIBBLEWHITE (manufacturer part no: 20-20326R) — a nitrided monoblock valve designed for the exhaust of customs and touring bikes. Combining a stainless steel stem and a Stellite tip, this valve offers increased wear resistance and reduced friction thanks to a special nitriding process (depth: 0.002"; surface layer: 0.0002"). The treatment also provides superior corrosion resistance and durability compared to hard chrome or electroplated nickel.
- Application: Exhaust, ideal for Vintage/Classic and Touring
- Tulip angle: 34°
- Head diameter: 1.630" (≈ 41.4 mm)
- Stem diameter: 0.2755" (≈ 7.00 mm)
- Construction: Stainless steel monoblock + Stellite tip, deep nitriding
- Fuel compatibility: leaded and unleaded; guides in cast iron or low-tolerance bronze
- Origin: Made in the USA
Lightweight and streamlined for optimized flow, the Black Diamond™ is suitable for high-torque motorcycles that demand wear resistance and thermal stability without compromise. Professional installation is recommended to ensure proper clearances and guides; ideal for Harley-Davidson FXSB, FXDWG, and FXDL (2017 models 1690 cc) and other similar machines.
