Vespa GTS250, GTV250 OEM Roller (21x17 - 11.2g)

Is your Vespa lagging when you twist the throttle, shuddering during acceleration, or struggling to maintain high-speed cruising RPMs? Over time, centrifugal force creates flat spots on your transmission's rollers, keeping your CVT from transitioning smoothly through its gear ratios. This Genuine OEM Piaggio/Vespa Roller Weight replaces worn, out-of-round weights to bring back the crisp off-the-line throttle response and fluid power delivery your maxi-scooter had when new. Key Features Eliminates Shifting Lag: Replaces flattened rollers to allow your ramp plate to expand fluidly, eliminating engine hesitation. Precision OEM Tuning: Calibrated by Piaggio to the exact 11.2g weight specification to keep your 250cc Quasar engine in its peak powerband. High-Durability Composite Shell: Molded from an advanced engineering polymer that minimizes internal friction and outlasts generic aftermarket rollers. Restores Factory Top Speed: Ensures the drive belt can travel to its maximum outer diameter on the pulley face for effortless highway cruising.
