 Genuine STM product

The STM clutch is designed to maximize the performance of your bike and ensures great durability.

Why install an STM clutch?
- Prevents engine over-revving
- Avoid rear wheel skipping
- It is possible to climb without using the clutch
- Allows controlled sliding of the rear wheels
- 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 born in the 90s, thanks to which STM has achieved success all over the world. The quality of STM products is embodied in the two victories in the Superbike World Championship together 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 the collaboration with STM. This leads to the development of cutting-edge components that combine operational reliability and precision. Building on the great 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 the certification of the company's Quality Management System in accordance with the new UNI EN ISO 9001:2015 standard.
