The result of the incredible work carried out by the R & D department of the OTK Kart Group, the Rookie is the latest evolution for the Mini category. The changes include both the new BSM4 braking system and bare frame geometries.
NEW SHAPES DESIGNED BY THE RACING TEAM
The Rookie frame has revised geometries compared to the previous model. The new design was developed according to the information collected on the track competing in the most important races in the cadet category. The aim was to be able to develop a geometry for the chassis to suit the different conditions of the track. As for aesthetics and design, the sticker kit was revised as a whole, inspired by RX R.
New among the revised details of the Rookie are 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 braking system. The BSM4 is now equipped with a 4-piston 7075 aluminum 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 7075 aluminum one-piece brake pump and with brake pipes covered in aeronautical steel mesh. All components in 7075 aluminum 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 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.
