The result of the incredible work by the R & D department of the OTK Kart Group, Rookie EV is the latest evolution of the Kosmic model for the Mini category. The changes, many and important, concern both the new BSM4 braking system and bare frame geometries. Without forgetting, however, some important details. Which one? Let's discover them all!

The Rookie EV bare frame has been revised in geometries, compared to the previous model Rookie. The aim, right away, was to be able to develop a geometry of the chassis, being able to suit the different conditions of the track. As for aesthetics / design, however, the sticker kit was revised as a whole, now clearly inspired by Mercury R, the new top model of the Kosmic 2019 range.

New, among the revised details of the Rookie EV, the adjustable front seat supports, making the seat assembly and the possible height adjustment easier: they allow a perfect coupling between the supports plate / level and the seat plate / level.

The R & D department of the OTK Kart Group completely redesigned the whole Rookie EV braking system. The BSM4, this is how it is called, is now equipped with a 4-piston ergal brake caliper, with automatic compensation of the brake pads wear. This is combined with the new self-ventilated brake disc with dimensions 160 x 10 mm. The braking system is provided with the ergal one-piece brake pump and with brake pipes covered in aeronautical steel mesh. All components in ergal are subjected to a thickness hard anodizing treatment, in order to give the components a considerable surface hardness against wear. Finally, the combined work between the pump and the brake caliper was taken care of with particular attention, in order to obtain a reduced / shorter pedal stroke (very important for the young drivers of the category), but at the same time also a greater distance of the brake pads from the disc.
