Clutch Kit -MALOSSI- Delta Clutch System Ø107mm- Yamaha/Minarelli 50cc 2-stroke

Centrifugal Clutch System with Clutch Bell for RACING Scooters

The system includes the famous:

patented adjustable clutch (Delta Clutch).
Additionally, a reinforced clutch bell (Wing Clutch Bell) with cooling fins, dynamically balanced, designed to prevent damage and developed for competition and sports use.

Delta Clutch

The Delta Clutch was developed for competitive scooter racing and quickly became the industry standard in its field as well as the key to improved performance.

The simplicity of the system allows for quick adjustment of the spring rate to accommodate centrifugal forces and also offers the option of swapping out springs with different spring rates (K-values).

The corresponding spring rates (K-values) are listed in the Malossi catalog.
In addition, this system allows for position adjustment of the small mass.
This affects the pressure between the friction material and the clutch bell. The small mass can also be replaced with other masses or clutch weights of varying weights.

The entire system is patented to prevent brazen attempts at copying and counterfeiting.

The Delta clutch has established itself as the standard product among many experienced tuning professionals, and the facts speak for themselves:
The Delta clutch is used by all racing teams and countless competition drivers, and sales figures are rising steadily.

As with all its other products, Malossi continuously tests the Delta Clutch in real-world conditions.
As a result, the clutch has been gradually optimized through small but crucial updates.
This has enabled the Delta Clutch to maintain its leading market position.
We are very proud that our Malossi clutches are asbestos-free.
Significant investment has been made in research to achieve the current quality standards regarding reliability and friction material.
We can now confirm with great confidence that we possess the exclusive formula for developing a high-temperature-resistant material that maintains its coefficient of friction even during long-term use.
