Valve White Diamond® - KIBBLEWHITE (Manufacturer's reference: 20-21016H)
Designed for demanding road and vintage engines, this White Diamond® exhaust valve combines modern design with robust finishing. Forged as a single piece to maintain lightness and strength, it has been analysed using finite element analysis (F.E.A.) and tested on a computerised flow bench to control profiling and surface quality. A 360° anodising treatment ensures uniform hard chroming where thermal and mechanical stresses are most intense.
Ideal for modifications on Harley-Davidson models (Softail and CVO listed as reference), this valve is aimed at riders who want a reliable part for their camshaft and exhaust seat. Its optimised geometry promotes a steady flow of gases and a smooth engine behaviour, while respecting the endurance constraints typical of large displacement motorcycles and touring.
Common compatibilities: Harley-Davidson FLSL 1750 Softail Slim (2021), FLTRXSE Road Glide CVO 1923 (2020), FLHXSE Street Glide CVO 1923 (2020).
