STM Dry Clutch Plate Set for Z40
Code: ADU-0300


Sintered metal type that can handle high engine power.
It has transmission capacity that cannot be compared to organic clutch discs, which are often used in standard vehicles due to cost considerations.
The steel discs are made from special steel developed for Ducati dry clutches.
This provides dramatic improvements in smooth disc movement, wear resistance, and quietness.
The operation is even smoother than the Economy Kit, providing a high-quality ride for many Ducati users in a wide range of situations, from racing to street use.The smoothness not only benefits the rider, but also protects your precious Ducati from excessive stress on the transmission, engine, and drivetrain.


The STM clutch is designed to maximize the performance of your bike and guarantees excellent durability.

Why install an STM clutch?
- Prevents engine over-revving
- Avoid rear wheel skipping
- Climbing without using the clutch is possible
- Allows controlled sliding of the rear wheel
- Manages the clutch closing phase when cornering (to avoid buckling)
- Thanks to the diaphragm spring, the release of the lever (start) is easier to manage.

STM is a versatile and dynamic company, entirely Made in Italy, whose business objective is innovation and research in the motorcycle sector. The first prototypes of the slipper clutch were created in the 90s, thanks to which STM has achieved success all over the world. The quality of STM products is tangible in the two Superbike World Championship victories it has won with the Ducati team. In 2003, the slipper clutch technology was extended from dry clutches to oil bath clutches, significantly widening its range of use.
Not only Ducati, but all Superbike teams require collaboration with STM. This leads to the development of cutting-edge components that combine operational reliability and precision. Building on the excellent achievements made in Superbike, STM extends its boundaries to the Motocross and Supermotard categories. This is why STM is today a racing art, combining technical perfection with Italian aesthetic flair, thanks to the selection and support of the best materials on the market and its own specialized team. In 2017, STM obtained certification of its quality management system in accordance with the new UNI EN ISO 9001:2015 standard.
