Kitaco Reinforced Auto Clutch Kit (Part No. 307-1414120)
This reinforced centrifugal (auto) clutch kit from Kitaco is designed specifically for tuned engines in Honda models with automatic centrifugal clutches. It provides much stronger power transfer and better durability than the stock clutch, which often slips under increased power from big bore kits, performance cams, or other upgrades.
Key Features & Benefits
-
7-disc clutch weight (stock is typically 4-disc) — significantly increases clutch capacity and torque handling.
-
Reinforced clutch springs — assembled for stronger engagement and to prevent slippage even under high power and high RPM conditions.
-
Maximum RPM rating: Up to 10,000 rpm — ideal for performance builds.
** Important: This kit is only compatible with 17/69 teeth primary ratio. **
Benefits for Tuned Engines: The stock auto clutch is often the weak point once you add power with an 88cc big bore kit or other performance parts. This reinforced Kitaco clutch kit solves that by delivering reliable power transfer without slipping, better heat resistance, and longer service life under hard riding. It makes your upgraded engine feel stronger and more responsive in real-world use.
