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 IT250 Motorcycle - Dual-Sport (1977-1983)
The Yamaha IT250, an enduro motorcycle produced from 1977 to 1983, was renowned for its robust off-road capabilities. Powered by an air-cooled, two-stroke, single-cylinder engine of 246 to 247cc, it was derived from Yamaha's YZ motocross bikes and incorporated advanced features for its time, such as CDI ignition and Monoshock suspension. While engine displacement remained consistent, the IT250 series underwent significant updates over the years. Yearly designations (IT250D, E, F, G, H, J, K) served as trim levels, indicating evolutions in chassis design and horsepower. For instance, the steering head angle was adjusted in 1979 to improve steering precision. In 1980, the Yamaha Energy Induction System (YEIS) and capacitor discharge ignition were introduced. 1981 and 1982 models saw suspension improvements, while 1983 brought a notable change with an altered engine bore and stroke (68 x 68 mm) and a more angular aesthetic. The transmission, initially 5-speed, became a consistent 6-speed from 1980 onwards. FAQ:
