The roller surfaces make for improve transfer of power meaning increased acceleration, with less focus on the top end speed. Power you can feel, but not quite as strong as the option from Malossi and co. Makes a great everyday vario. Delivery includes: 2x sets vario-rollers 16x13 at 6.9g and 6.3g and 1 x set of sliders. Suitable for BSV GP, SP; Honda Dio SP, Dio SR, Vision, Vision Met-In; HSC SC01 and Peugeot ST Rapido scooters.
