NARAKU Sport Torque Spring V.2 - Ref. NK900.66
Replace your torque spring with this Sport V.2 model from NARAKU, designed for the variators of small 50 cc scooters and quads. Made from modified alloy, this spring offers improved resilience and above-average strength, making it suitable for transmission adjustments and daily or sporty use.
The spring affects the variator's response: by slightly delaying engagement, it alters the engine's pickup RPM and can contribute to better acceleration from a standstill depending on the setup and adjustment. Its replacement is recommended during engine tuning or optimisation of the running gear. Markings on the spring allow for quick identification of the rating and strength for precise selection during maintenance.
This product is intended for motorcyclists and DIY enthusiasts looking to enhance or adjust the variator's pickup curve without promising unverified technical gains: always tailor the choice of spring to your configuration and driving goals.
