variator NARAKU HS Racing V.2 for Kymco, SYM, 139QMB/QMA, 20x38mm

The second generation of the Naraku HS variator has been finely optimised. Alongside the weight reduction from 157g (NK900.20) to only 127g (NK900.26), the anti-friction bush has also been fitted with a failsafe that prevents the bush from wandering, even in high-end, tuned engines. The optimised roller surface drastically improves acceleration and top-end speed. Variator size: 20x38mm. Variator weights: 6x5.5g (16x13mm)
