Description
The EBC Brakes CKF kit is a tough carbon fibre impregnated moto-x/ATV clutch which is longer lasting and grippier than standard cork based units (friction plates only).
Carbon fibre clutch plates are designed to handle the higher temperatures encountered in racing while being gentle enough for every day riding. Each kit is measured to the perfect stack height and should only be fitted as a whole kit. Soak clutch plates in the correct quantity of manufacturer's recommended drive case oil before installation.
Never use automatic transmission fluid. We strongly recommend that this clutch is fitted by a professionally trained mechanic. It is best to fit new clutch springs at the time of changing clutch plates due to heat fatigue of old springs. We sell a range of clutch spring sets. Before riding your motorcycle please ensure you are comfortable with the new lever force and can easily disengage the clutch with minimal hand pressure. Have an experienced rider test the machine.
FEATURES
- Include carbon fiber impregnated friction plates
- Tough clutch plates extend engine life
- Improve drive
- Increase the heat threshold of the clutch
- Improve rider feel

Vehicle Information
Yamaha YZ450F Dirt Bike (2003-2026)
The Yamaha YZ450F, a dominant force in motocross, has been continuously refined from 2003 to 2026. This high-performance dirt bike is renowned for its powerful 449cc engine and advanced chassis, designed to deliver a competitive edge and an exhilarating riding experience. Over two decades, Yamaha has consistently pushed boundaries, integrating cutting-edge technology and rider-focused improvements. The YZ450F has undergone several significant generational shifts. The 2003 model saw an engine displacement increase to 449cc and a lighter frame. A major overhaul in 2006 introduced an all-new aluminum single-backbone frame and KYB SSS forks. The revolutionary reversed cylinder engine design debuted in 2010, followed by the adoption of fuel injection in 2012. The 2014 model brought a new bilateral aluminum beam chassis. The 2023 iteration marked a complete redesign, featuring a lighter, more compact engine, a new frame, dry-sump lubrication, and advanced electronic rider aids like Traction Control, all controllable via the Yamaha Power Tuner App. While 2024 carried over these updates, 2025-2026 are expected to bring further refinements.

| Engine Oil and Oil Filter | Every 5 to 10 hours | Change both together. 5 hours for aggressive/race-level riding; 10 hours for recreational riding. |
| Air Filter | Every 2 to 15 hours | Intervals vary significantly by model year and riding conditions. For some years (e.g., 2003, 2006, 2018), 2 hours for aggressive/race, 5 hours for recreational. For others (e.g., 2010, 2022, 2025, 2026), 5 hours for aggressive/race, 15 hours for recreational. Clean and re-oil regularly. |
| Spark Plug | As needed | No fixed replacement interval. Inspect regularly for wear, fouling, or incorrect gapping. Clean, re-gap, or replace as necessary. |
