The Polini Minibike 910 RS air two-color part number 143.000.253 is one of the most iconic and appreciated racing minimotos in the track racing world.
Often referred to as “the champions’ minimoto,” Polini minibikes have helped develop world-famous riders including Valentino Rossi, Marco Melandri, Dani Pedrosa and Franco Morbidelli.
The new 910 RS features a modern two-color racing livery designed to enhance the compact and aggressive styling of a minimoto built specifically for introducing young riders to track riding.
Thanks to its lightweight alloy chassis, low weight and 6.5” wheels, the Polini 910 RS delivers intuitive and precise handling, helping riders progressively learn braking control, racing lines and throttle management.
The air-cooled 4.2 HP 2-stroke engine provides strong performance combined with reliability and easy maintenance.
Entirely manufactured in Italy at the Polini headquarters in Alzano Lombardo, it combines racing passion, technical quality and rider development.
