The STM slipper clutch is a technology designed and implemented on the motorcycles to avoid the dangerous tire hopping effect, hopping due to the intervention of the engine brake during the deceleration phase. The slipper operates only and exclusively during the brake phase, when the motor generates negative torque. The intervention of the engine brake on the rear wheel of a motorcycle is invasive to the point of causing the wheel to leap, with consequent loss of traction of the tire. The anti-skid STM clutch keeps the compound motion during deceleration.
The STM clutch is a very high quality component made of high quality materials such as ergal that make it much lighter than an original clutch (OEM) with finishes and craftsmanship of the highest level. Equipping the bike with any of the STM clutches allows an overall improvement of the vehicle's performance, also extending the life of the engine.
A versatile and dynamic company, STM ITALY has the business purpose of innovation and research in the motorcycle industry. The first prototypes of slipper clutch originated in the 90s, thanks to which STM is successful worldwide. The quality of the STM products is cynetized with 2 superbike world championships won with the DUCATI team. In 2003 the slipper clutch technology was extended by dry clutches to wet clutches, increasing its range of use enormously. Not just Ducati, but all Superbike teams require STM collaboration, which leads to the development of state-of-the-art components that combine reliability with precision in operation. Based on the excellent work done in Superbike, STM extends its boundaries to the Motocross and Supermotard categories. This is why today STM is racing Art, thanks to the choice and the help of the best materials on the market and its own specialized team, combining technical perfection and Italian aesthetic taste. In 2017 STM ITALY is in compliance with the new UNI EN ISO 9001: 2015 standard, obtaining the certification of the company quality management system.
