The Premier Clutch Fibre Kit (PBCK5638) is a high-quality replacement friction plate set for the KTM SX-F 450 and SX-F 505 from 2007 onwards. These motocross machines demand a clutch that can handle repeated high-RPM launches, snap throttle inputs, and aggressive rut riding — conditions that quickly wear standard fibre plates.

Premier's CK Series uses anti-swell, cork-based, asbestos-free friction material that delivers consistent bite and heat resistance through extended moto sessions. Replacing worn plates with this kit brings back the snappy, responsive clutch feel that MX riders expect from the SX-F platform.
