MALOSSI Push Spring designed to fit in the variator of urban scooters. This reinforced spring adheres to the manufacturer's specifications 57.8 x 91 mm / Ø4.0 mm / 5.5K and aims to stabilize the pressure exerted by the secondary transmission system for a more linear engine behavior during acceleration.
This Malossi spring is aimed at 50cc scooter riders seeking a more consistent variator response in daily driving. Its geometry and stiffness (5.5K) are designed to maintain endurance suitable for the demands of city riding — repeated starts, stops/accelerations, and dense traffic circulation. Simple installation, to be mounted in the variator while following the manufacturer's recommendations and balancing with other transmission elements (rollers, pulleys, etc.).
Notable compatibilities: APRILIA SXR 50 (2023‑2025) and other urban scooters with similar specifications. Always check dimensions and desired behavior before installation.
