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

- Improve rider feel

Vehicle Information
Yamaha YZ85 Dirt Bike (2002-2026)
The Yamaha YZ85 has been a dominant force in youth motocross from 2002 to 2026, consistently powered by an 85cc liquid-cooled, two-stroke, single-cylinder engine. This high-performance dirt bike is designed for aspiring racers, offering a blend of power and agility. Throughout its production, the YZ85 has been available in two primary trims: the Standard YZ85 with 17-inch front and 14-inch rear wheels, and the YZ85LW (Large Wheel) featuring larger 19-inch front and 16-inch rear wheels, catering to taller riders. While the core 85cc engine remained, the YZ85 underwent significant evolution. A major "ground-up redesign" in 2019 introduced a new engine with Yamaha Power Valve System (YPVS) for broader power delivery, along with updated suspension, swingarm, brakes, and ergonomics. Further revisions in 2022 refined the styling and chassis, including a flatter seat, narrower fuel tank, reworked air intake, and a new lightweight aluminum subframe, making it resemble larger YZ models. The 2026 model largely carries over these enhancements with updated graphics. FAQ:
