The K-Tech ‘Pro Valve’ System is a precision-engineered upgrade for WP 48.00mm AER forks used on Motocross 2-stroke models from 2016 on wards. Replacing the original compression and rebound damping assemblies along with the adjustment needles, it delivers refined damping behaviour and a wider usable adjustment range. The result is improved ride quality, increased stability, and consistent, responsive feedback across varied terrain.
