Key Features

• Complete Secondary Transmission: Includes the rear clutch shoes, heavy-duty torque spring, and the matching 19-tooth clutch bell for a total drivetrain overhaul.
• Optimized Torque Driver: The 140mm pulley is designed to manage belt tension precisely, preventing "bogging" during uphill climbs and ensuring smooth downshifting when coming to a stop.
• Precision 19-Tooth Spline: The clutch bell is manufactured with a high-strength 19-tooth spline interface to ensure a perfect, slip-free lock onto your transmission's input shaft.
• Enhanced Heat Dissipation: The 135mm clutch bell features a vented design to reduce heat buildup, which helps prevent the clutch pads from glazing and extends the life of your drive belt.
• Versatile Application: A direct "drop-in" replacement for almost all Chinese-manufactured 150cc 4-stroke engines found in scooters, mopeds, buggies, and go-karts.
