EBC Brakes Standard CK Series Clutch Friction Plate Kit | CK4478

Upgrade your motorcycle's clutch performance with the EBC Brakes Standard CK Series Clutch Friction Plate Kit (CK4478). Designed as a direct drop-in replacement for worn or slipping factory plates, this full engine set resets your clutch pack back to as-new operating height and factory specifications.

Premium Cork-Based Construction

The CK Series plates are manufactured using an OEM-style, cork-based friction material impregnated with aluminum particles. This advanced compound significantly increases overall wear life and maximizes heat resistance. EBC’s highly compressed construction engineering actively avoids clutch swell and drag, providing consistent drive engagement, smooth take-up, and precise control under all operating temperatures.

Key Features & Benefits:

• Complete Engine Set: Includes a full set of friction plates specifically measured for a perfect drop-in stack height alignment.
• Anti-Swell Compound: Compressed cork and aluminum particles resist thermal expansion, stopping clutch slippage and drag before it starts.
• Street & Dirt Versatility: Specially optimized for general-purpose street, sport, touring, and select off-road powersports applications.
• Direct OEM Fit: Replaces factory friction discs identically in profile, ear design, and technology.

Fitment & Compatibility

The EBC CK4478 kit is engineered for specific motorcycle applications. To ensure optimal performance and complete powertrain compatibility, please verify your vehicle details below:

• Kawasaki KX80 (1989-1997)
• Kawasaki KX100 (1995-1997)

Note: Fitment may depend on engine size, trim level, model year, and existing aftermarket modifications. Please verify compatibility with your specific motorcycle model, year, and case design before ordering.

Important Installation Requirements:

• Critical Oil Soak: All cork-based friction plates must be thoroughly pre-soaked in clean, standard drive case oil for a few hours prior to installation to prevent heat scorching or premature burning upon initial start-up.
• Oil Warning: Do not use with 100% full-synthetic oils unless specifically permitted by your vehicle manufacturer, as some heavy synthetic additives can induce slippage in standard cork arrays.
• Components Not Included: This package contains the friction plates only. It does not include standard steel separator plates, driven plates, inner hubs, or heavy-duty clutch springs. EBC strongly recommends inspecting your steel separator plates for warping and swapping out worn clutch springs during installation.
