Article information

Revolutionary clutch system developed and produced by JCosta.

Revolutionary transversal clutch system that work with the use of centrifugal force. This so-called ‘transversal operation’ is comparable to the way the well-known JCosta variators work.

In this clutch housing, weights have been added which are pushed outwards by this centrifugal force as the engine speed increases. Due to this increasing force, these weights exert more and more pressure on the original clutch springs as the rpm increases. This makes the clutch work more direct yet smooth which results in:

- Aggressive and faster acceleration.
- A better, more sensitive reaction to the throttle.
- Improved engine brake
- More retention when you close the throttle.
- Less extreme use of the brakes.

The JCosta clutch housing is CNC-milled and is "hard-anodised". Hard anodising is a process in which a very hard wear-resistant layer is applied to the aluminium, making the treated article suitable for extremely heavy use.
