Outer Drive Face | Vespa GTS 250/300 Piaggio BV/MP3

Description

Stop letting a grooved, uneven, or glazed drive pulley degrade your scooter’s performance. This premium aftermarket outer drive face (fixed half-pulley) works in perfect unison with your variator to deliver crisp, predictable acceleration and smooth gear-ratio transitions. Engineered to meet strict factory tolerances, it replaces worn-out plates that cause premature drive belt wear and sluggish top-end speed.

Key Features

• Restores Smooth Acceleration: Eliminates deep ridges and grooves worn into the pulley face by old drive belts, restoring seamless CVT shifting
• Integrated Turbine Cooling Fins: Precision-cast radial air-induction blades draw cool air through the transmission case to lower belt operating temperatures
• OEM-Spec Spline Machining: Perfectly matched center spline pattern locks tightly onto the crankshaft with zero slop or play
• Optimized Face Angle: Engineered to the precise factory angle for maximum belt contact — prevents slipping under heavy loads
• Replaces OEM: 840193, 831375, 1A013202
