All the improvements brought to 2019 chassis have been thought, developed and tested by the Tony Kart official racing team during the most important competitions around the world: these are the essential conditions for giving all the drivers high quality and reliable karts.
For Racer 401R and Krypton 801R, both available in direct drive and shifter version, the bare frame geometry are unchanged, the most interesting innovations concern the componentry.

The Rookie has new bare frame geometry, a new brake system, new stub axle and seat available in two sizes.


Thanks to computer CFD simulations, the technicians of the Research and Development Department of the OTK Kart Group developed the new M7 Nassau panel for the Racer and Krypton: its shape is characterized by a unique and revolutionary design, perfectly integrated with M6 bodyworks.
Another great change is the integrated floor plate, a special type of floor plate whose configuration completely seals the frame frontal area, considerably improving the aerodynamic output.
