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
Honda CRF450X Dirt Bike (2005-2026)
The Honda CRF450X is a robust off-road motorcycle, designed for trail riding and competitive racing, and is 50-state off-road legal. Produced from 2005 through the anticipated 2026 model year, it is primarily offered as a single trim, with significant updates marking generational changes rather than distinct trim levels. It is powered by a liquid-cooled single-cylinder four-stroke engine with a consistent 449cc displacement and bore/stroke measurements of 96.0mm x 62.1mm. The CRF450X has undergone three main generational changes. The first generation (2005-2007) featured a 40mm Keihin flat-slide carburetor and a five-speed transmission. The second generation (2008-2017) introduced minor updates such as a Honda Progressive Steering Damper and a revised accelerator pump. The third generation, launched in 2019 and continuing through 2026, brought a complete overhaul, including the adoption of fuel injection (PGM-FI), a new chassis based on the CRF450R, and a wide-ratio six-speed transmission. The 449.7cc Unicam engine was also revised for off-road appropriate power. FAQ:

Maintenance
| Component | Interval | Details |
| Engine Oil and Oil Filter | 10-15 hours (recreational) or 5-10 hours / 6 races (aggressive). Alternatively, 6,000 km for general Honda engines. | The CRF450X uses a split lubrication system for engine and transmission. It is recommended to change engine oil and filter together. |
| Air Filter | 10-15 hours (recreational) or 2-10 hours / after every ride in dusty conditions (aggressive). | Regularly clean and service the air filter, especially in dusty conditions. Replace if there are signs of damage or degradation. |
| Spark Plug | Periodic inspection and replacement as per the maintenance schedule. | Inspect for wear, deposits, and proper gap. Maintenance is part of the competition use schedule for later models. |
| Coolant | Every 2 years, or 40-50 hours / at least once per season for severe off-road use. | Always use Honda-recommended silicate-free coolant to prevent overheating and corrosion. |
