The EGIG One Finger Clutch 2.0 Pro is a 6-disc clutch for powerful Vespa smallframe engines and has been designed to combine high torque with low operating force requirements. The individually configurable number of springs allows the clutch to be configured in such a way that it can still be operated with one finger on the lever even in powerful setups, while at the same time reliably transmitting power up to around 100 hp.
6-disc smallframe clutch One finger clutch concept Version with Poligon hub Carbon pads
The One Finger Clutch 2.0 Pro is based on a 6-disc package consisting of carbon pads and matching steel discs. Thanks to the increased friction surface, the number of springs and spring stiffness can be significantly reduced compared to conventional smallframe clutches without the clutch slipping. The result is a clearly defined separation point and short lever travel with high power transmission.
The variant described here is equipped with a Poligon hub and is intended for suitable primary drives with a corresponding mount. In conjunction with suitable peripherals, the clutch is suitable for a wide range of applications - from powerful touring engines to very sporty setups.
The clutch is designed in such a way that the transmittable torque can be finely scaled via the fitting of outer springs and optionally available harder inner springs. The following combinations are given as guide values:
With standard spring configuration:
In conjunction with optional harder inner springs:
This allows the clutch to be adapted very precisely to the engine power, intended use and desired manual force - from comfortably light to very high torque reserves for demanding racetrack engines.
The scope of delivery includes a clutch cover spacer with a thickness of 2.5 mm. This provides the necessary installation space under the cover without having to make complex adjustments to the housing geometry. The use of a suitable oil is crucial for clean separation and defined engagement; we recommend using classic 80W90 transmission oil or SAE30 engine oil, depending on the preferred tuning and other engine peripherals.
Note: The clutch is designed for smallframe engines with a suitable Poligon primary. Before fitting, check the existing hub mount and the installation space under the cover.
