Description Technical Specs
 
This STM slipper clutche fits the following Aprilia bikes: Aprilia Dorsoduro 750: FAP-S030 Aprilia Shiver 750: FAP-S030  Thanks to STM Technologies, the first and only slipper clutch for the brand new Aprlia Dorsoduro 750 has been born. The prototype and test results where far beyond expectations, which decreed the absolute need of the STM clutch to definitely appreciate all the performance the Dorsoduro has to offer. Engaging of gears is softer and easier, approach corners in complete safety, less consumption of the mechanical parts involved, constant and responsive feedback from the lever, best traction control and a complete adaptation of the engine brake to individual riding style? all these features make this clutch the main accessory to appreciate the wonderful characteristics of this bike.  Slipper clutch main features: Primary Diaphragm Spring: 125mm in diameter for more accurate and uniform pressure on the plates, and to aid in better starts. Secondary Diaphragm Spring: Interchangeable and available in 10kg increments to adjust the amount of engine brake to each individual riding style in a fast and accurate way. FLS III (FORCE LUBRICATION SYSTEM), superior lubrication of the internal clutch parts which leads to increase cooling and longetivity of the unit as a whole. Billet machined from Ergal 7075 material, ensuring above average lightness and duration. Disc Pack and basket: Original replacement Aprilia.  Features: slipper system - device to control the opening - Forced Lubrication System 3 Compatible disc pack: original Aprilia (not included) Compatible basket: original Aprilia (not included) Tools: pressure plate mounting tool code UTL-0030 (recommended) UTL-0020 in case of the FAP-S010.  Note: when choosing the primary spring keep in mind that the greater the spring tension, the greater the pressure on the disc pack and the smaller the slipping in acceleration. When choosing the secondary spring remember that the greater the spring tension, the greater the engine brake in deceleration
Features
  • The Evolution Slipper Clutch was the very first slipper clutch to utilize a Diaphragm spring! Of course the Evolution uses STM staples like 'Ball & Ramp' actuation for smooth slipper clutch operation, and the STM exclusive 'PEP' - Progressive Engagement Plate to decrease the abruptness during closing of the clutch. In addition, it uses a 90mm Diaphragm Primary Spring and an 85mm Diaphragm Secondary Spring. By using diaphragm springs in both the primary and secondary .. the Evolution Slipper Clutch offers superior adjustability to suit any riding style and engine modification. The primary spring controls the pressure on the clutch pack during lock up. STM 90mm diaphragm primary springs are weighted in Kilograms and offered in 10Kg increments. There are 9 different weights to choose from (sold individually). Through the use of varying weights, the engine builder can adjust the amount of pressure on the clutch pack to compensate for any engine modifications and subsequent increases in horsepower. The secondary spring is what controls the amount of engine brake. The lighter the secondary spring, the less engine brake; the heavier the secondary spring, the more engine brake. The 85mm diaphragm secondary springs are weighted in Kilograms and offered in 10Kg increments. There are 6 different weights to choose from (sold individually). Through the use of varying weights, the rider can adjust the amount of engine brake desired to fit their individual riding style.
