The MT-SS1234-411C 10T centrifugal clutch is designed for 3/4" crankshafts and 40/41/420 chain, delivering smooth engagement at higher RPM for performance minibikes and go-karts. See full product details below.
The MT-SS1234-411C centrifugal clutch is a performance-oriented drivetrain component designed for small engines with a 3/4" crankshaft. Built for use with #40, #41, and #420 chain, this clutch provides reliable power transfer and consistent engagement for minibikes, go-karts, and recreational vehicles.
Unlike lower engagement clutches, this model engages at approximately 3000 RPM, delivering a more responsive and aggressive takeoff. This higher engagement speed helps keep the engine in its power band, improving acceleration and overall performance.
Centrifugal clutches automatically engage as engine RPM increases, eliminating the need for manual clutch operation. This makes them simple to use while still offering strong performance for a wide range of builds.
The 10 tooth sprocket provides a balanced setup between acceleration and top speed, making it ideal for general-purpose riding and performance-oriented applications.
Important Fitment Notice: Designed for engines with a 3/4" output shaft using #40/41/420 chain. Not compatible with 5/8" shafts or #35 chain setups.
This clutch engages at approximately 3000 RPM.
It fits engines with a 3/4" crankshaft.
It works with #40, #41, and #420 chain.
Yes, the 3000 RPM engagement makes it better suited for performance applications.
For heavier vehicles or higher horsepower engines, a torque converter is recommended.
Complete your drivetrain setup with ARC Racing components including chains, sprockets, and torque converters. Proper gearing and clutch selection are critical to achieving the best performance and durability from your setup.
