MHR WING CLUTCH BELL – MADE IN ITALY NEW Wing Clutch Bell – Forged Steel Alloy for Automatic Scooters CVT The clutch bell has been developed and manufactured in our Calderara di Reno engineering plant using proprietary processes. Machined from a single steel alloy-forging, surface hardened and tempered, no welds, these new clutch bells feature an innovative manufacturing process and attention to the finest details guarantee a highest quality product. Designed and developed by our engineering department and handed over directly to our manufacturing, where our latest generation of Numerically…

Clutch Bell with Reinforced Cooling Ring The clutch bells with reinforced cooling ring consist of a finned annular reinforcement producing excellent heat dissipation caused primarily from stand still starts and quick accelerations from low speeds. This technological innovation resulted from extensive testing within the Scooter racing circuit. The clutch bell design is based on the following principals: greater heat transfer surface area (finned section) lowers the working temperature of the clutch bell which dramatically increases the systems durability. The clutch system is enormously…

Maxi Clutch Bell Technical Specifications Clutch Bell forged using Fe DC04 deep-drawing steel; Carbon steel centre hub made of round stock and TIG welded; Anti-vibration band welded using a 3 point 120° pattern; 100% dynamically balanced; Surface hardened through nitriding.

WING CLUTCH BELL Technical features Interchangeable with the original bell. Designed for maximum resistance with minimum weight. Clutch Bell in deep-drawn steel, obtained by cold heading. Central hub made from machine carbon steel billets with TIG welded filler material. Finned carbon steel reinforcement ring obtained through chip removal, TIG welded. Pins for starter masses in carbon steel and studded. Soft nitriding thermochemical treatment.

POWER UP CLUTCH BASKET TECHNICAL FEATURES In high-strength steel with hardening surface treatment to improve resistance to wear, and consequently its service life. A TIG welded reinforcement ring on the outer bell diameter to efficiently counteract the centrifugal force developed by the higher rotation speed. For original clutch and Malossi POWER UP CLUTCH SYSTEM.

Clutch hub made of special alloy steel, CNC machined. For original clutch and Malossi POWER UP CLUTCH SYSTEM.

Technical Specifications Clutch Bell forged using Fe P04 deep-drawing steel; Carbon steel centre hub made of round stock and TIG welded; Surface hardened through nitriding; Finned reinforcement ring, made of machined carbon steel, black oxide surface finish, press fit; 100% dynamically balanced.

Modifying the engine of a Vespa to increase its performance does not just entail simply changing the inner engine parts. Every modification affects all the engine components taking them over the modest limits for which they were designed. What this means is that apparently secondary components, such as the clutch, require suitable modifications and improvements to be able to better withstand the increase in power and torque, and to ensure the legendary reliability of the most classic scooter of them all. So, the new power up clutch basket has been developed by the technical department of…
