Vortex clutches employ modern technologies that virtually eliminate engine bogging. While all other disc clutches attach springs to the pressure plate to control clamping force, Vortex springs are attached to the levers to control centrifugal force. By controlling force where it is generated instead of where it is applied, Vortex clutches react more quickly to changes in engine rpm. Less energy is lost to clutch heating leaving more energy for acceleration. Smoother engagement and faster acceleration are guaranteed!
Vortex clutches are user friendly. The clutch springs are adjusted quickly, easily and precisely without dial calipers. Air gap is not an issue with the Vortex clutch, reducing the amount of adjustments. Clutch rebuilds are inexpensive, simple, and take a matter of minutes using only a T-handle wrench.
Vortex two disc clutches comes with Black Springs standard. You can use the selector above to have your clutch equipped, and shipped with the silver or gold springs installed instead of the black springs.
