The new model of the Tony Kart range replaces the Krypton 801 R and inherits all its main features, including the frame entirely made of D. 32 mm chrome molybdenum tubes. There are several new features, among which the M10 fairing kit born from the synergy between the Tony Kart Racing Team and the OTK Kart Group R&D department.
Constantly developing
The new TDX, heir to the Krypton 801 R, incorporates all the winning features of Tony Kart's top-range model, the Racer 401 RR. The main difference between TDX and Racer is the diameter of the chrome molybdenum steel tubes that make up the frame: D. 32 mm for the TDX, D. 30 mm for the Racer. No difference between the two models, however, as far as the latest developments and changes introduced, starting from the M10 fairing kit, combined with the M7 number plate spoiler now in green, as well as some technical solutions aimed at optimizing the driving position. The highest attention to details, the highest quality of raw materials used for each component and the continuous evolution of the product, fed by the Tony Kart Racing Team's work on track, remain unchanged.
M10 fairings
Aerodynamics has been a central element in the work of OTK Kart Group's R&D department for several years, through in-depth wind tunnel tests and CFD computer simulations. The M7 number plate spoiler, with its innovative design and able to reduce the aerodynamic resistance, with the consequent increase of the performance, is now joined by the new M10 fairing kit, realized to further refine the Tony Kart chassis under the aerodynamic profile. The side bumpers have been lightened and streamlined, favouring the cooling of the rear tyres, while the front spoiler and the rear protection adjustable in width, comply with the latest FIA directives in terms of safety. There is also the "integral" floorplate, inherited from the Krypton 801 R, which completely covers the area between the chassis tubes at the front, further optimizing aerodynamics.
BSD Brake caliper
The Tony Kart TDX, like the single-speed Racer 401 RR, is also equipped with the BSD braking system. This system, which bears the OTK Kart Group signature, is the same one fitted on the karts that won the OK and OKJ world titles two years in a row, in 2020 and 2021. The rear brake caliper is forged in a single piece: inside there are two D. 34.5 mm pistons with stroke recovery, combined with a two-piston brake pump and to the brake line kit with PTFE inner tube. The material used to manufacture the brake caliper and pump kit is Ergal, featured by excellent mechanical strength, while the hard oxidation process reduces wear on the moving parts.
Driving position
A fundamental aspect for every driver is the driving position: for this reason, OTK Kart Group's R&D department constantly works to propose continuous improvements and refinements. Among them, the Tony Kart TDX introduces more flexibility in the footrest adjustment and features new seat supports. The HGS steering wheel is the same as the one on the Krypton 801 R: equipped with high grip and comfort rubber grips, it considerably increases the driver's driving sensitivity. The steering wheel is combined with an angled hub for a fully ergonomic driving position.
BSS and BSZ brakes
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.
