Features

NARAKU NK900.76 Backspring

Designed for urban scooters, this NARAKU Sport V.2 backspring replaces the original variator part to refine the behaviour of the CVT transmission. Made from a modified alloy, it offers improved resilience and above-average strength, ensuring durability suitable for daily urban use.

  • Function: variator backspring
  • Effect on behaviour: softens the initial response of the variator and promotes a higher engine speed before full engagement — useful during tuning and for a more responsive start.
  • Identification: markings on the spring to identify the resistance and facilitate selection during installation.
  • Packaging: sold individually
  • Manufacturer reference: NK900.76

Replacement is recommended during engine or variator tuning. Technical installation is advised by a professional if you are not familiar with the CVT transmission (rollers, belt, clutch bell). Examples of commonly affected urban models: Vespa Primavera 150 IGET, Kymco People 125, Sym Jet 4 125.
