PROX Smooth Clutch Disc Kit (manufacturer part number: 16.S23016) — a kit designed to properly refurbish the clutch of your machine. Developed from competitive experience, this disc set matches the specifications of the original equipment for easy installation and seamless integration with OEM components. Ideal for motocross and quad riders who want to regain reliable clutch control after hours on the track.
Perfect for regular maintenance or preparation before an off-road season, these discs facilitate the restoration of the transmission and help achieve a clean engagement range. Suitable for both Quad and Cross environments — recent models such as YAMAHA YZ 250 (2026), FANTIC XX 250 (2026), or FANTIC XEF 450 RALLY (2024) are among the motorcycles concerned. Installation is recommended by a qualified mechanic to ensure proper clutch adjustment and regain a crisp lever feel.
