NARAKU Spring Kit (manufacturer's ref: NK900.51)
Kit of 3 counter-pressure springs for variator, developed for riders seeking finer tuning of the secondary transmission. The Naraku Sport V.2 springs are made from a modified alloy offering improved resilience and above-average mechanical strength. Designed to replace the original springs during engine tuning or optimisation, this kit allows for adjustment of the variator engagement curve.
In practice, a firmer spring will delay the variator engagement, altering the throttle response and RPM during the start-up phase; a softer spring will produce the opposite effect. These characteristics make this kit a relevant choice for Quad, Vintage/Classic, Urban, and Sport/Racing environments. Examples of compatible models: GENERIC TOXIC 50 (2018), EXPLORER SPEED 50 (B92) (2018), BEELINE PISTA 50 R AC (2018).
