NARAKU Clutch Spring - Manufacturer Ref. NK900.78
Designed for the clutches of 125/150 cc scooters, this NARAKU clutch spring fits original mounts and compatible GY6 sports clutches. Sold individually, it is aimed at urban riders looking to adjust the engagement point and responsiveness of their primary transmission.
Technically, installing a stiffer spring alters the engagement speed: depending on the configuration and the number of springs on the mount, the manufacturer indicates indicative variations (for example, an increase in engagement speed of around +1500 rpm on some 2-strokes and up to +2000 rpm on 4-strokes). These values remain dependent on the vehicle, the pads, the bell, and the overall adjustment of the variator.
Ideal for urban use where a more immediate clutch response at take-off and better control of engine torque is desired, this NARAKU spring allows for fine-tuning the behaviour of a standard clutch. Check compatibility with your model before installation and always replace according to manufacturer recommendations.
