Unfortunately, most original clutches engage much too early. Unfortunately, at this cut-in speed, the engine still has far too little power to properly accelerate the vehicle from a standstill. This almost always results in a bad start at traffic lights or going downhill. Starting in pairs is even more difficult. Remedy only makes a sport or racing clutch.
NARAKU here offers a solid sports clutch suitable for everyday use. The clutch is equipped with medium-strength clutch springs, which raise the number of revolutions of the clutch compared to the original by approx. 1500-2000 revolutions. This allows the engine to rev higher before it is under load and can provide more engine power when starting. By using other clutch springs, the speed can be changed again.
