Malossi MAXI DELTA SYSTEM clutch and bell D 134

The Malossi MAXI DELTA SYSTEM Ø 134 mm clutch and bell is a complete centrifugal clutch group designed for racing scooters. This system consists of the famous patented adjustable Delta Clutch and the reinforced anti-explosion Wing Clutch Bell. The bell is equipped with dynamically balanced cooling fins, making it ideal for racing and sport use.

The Delta Clutch is a clutch developed for racing scooters and has become an essential reference tool for vehicle tuning. Its simplicity allows for quick adjustment of the counter spring tension against centrifugal force and replacement of the spring itself with others of different stiffness, available in the Malossi catalog. In addition, it is possible to vary the position of the weight that determines the pressure of the friction material against the inner wall of the bell and replace the weight itself with one of different weight.

This system is patented to protect it from counterfeiters and copiers who try to bypass the invention. It has been recognized by the most qualified technicians and is adopted by all racing teams and a wide range of sports enthusiasts. Its popularity is constantly increasing.

Malossi has always followed the product over the years, making small but important optimizations to keep it at the forefront. It is important to emphasize that asbestos has never been used in Malossi clutches, which is a source of pride for the company. To ensure the quality and reliability of the product, the company has invested heavily in research, especially on friction materials. It can now boast exclusive formulas for producing materials resistant to high temperatures and capable of maintaining a constant coefficient of friction even under prolonged stress conditions.

The Wing Clutch Bell is made of DC04 mild steel through cold stamping. The central hub is made of carbon steel obtained from a bar and welded using the Tig method. It has undergone a soft nitriding thermochemical treatment. The finned reinforcement ring is made of carbon steel by chip removal and has undergone a surface burnishing treatment. The bell is 100% dynamically balanced.
