The Racer 401 chassis, in the version featured by the "double R", takes to the maximum evolutionary expression the Tony Kart's top range model. As always available in single gear, shifter and DD2 versions, it has a new livery and introduces several news born from the synergy of Tony Kart Racing Team and OTK Kart Group R&D department.
Fairing Kit M10
For several years, OTK Kart Group's R&D department has been focusing its attention on the aerodynamic refinement of its products, through CFD computer simulations and in-depth wind tunnel tests. This work initially led to the introduction of the M7 number plate spoiler, with its innovative design and ability to reduce aerodynamic resistance, resulting in increased performance. The M7 is now combined with the new M10 fairing kit to further refine the aerodynamic profile of the Racer 401 RR. The weight-saving side bumpers have been streamlined to aid rear tire cooling. In addition, the front spoiler and the rear protection, adjustable in width, meet the latest FIA regulations. Not to forget is the "integral" floorplate, already featured on the previous Racer 401 R model, which further improves aerodynamic efficiency.
BSS and BSZ Brakes
Reserved for the Shifter
The OTK Kart Group's winning philosophy remains unchanged, using only selected materials of the highest quality, processed with machines and automated processes that ensure the full reproducibility of each component and the highest quality standards. This approach is more fundamental than ever when conceiving a braking system, especially for the shifter categories. Braking, in fact, in these classes has a great impact on the performance and Tony Kart has proved to be the technical reference point, after the double world title in 2021 in KZ. The BSS system, featured by monobloc front calipers, with 4 D. 22 mm pistons with stroke recovery, is now combined - only for the shifter version of the TDX - by the BSZ system, now standard, with larger diameter pistons for a matchless modularity of braking. The TDX is also available for the DD2 category, equipped with the BSS braking system only.
