The Tonykart Racer 401 T, confirms itself at the top of the OTK range. The chassis is made entirely of Ø 30 mm tubes and OTK’s renowned manufacturing quality is unchanged. The 2025 model introduces new features such as the new chain tensioner and new 2025 graphics.

The Racer 401 is the spearhead of Tony Kart's success-rich history. Throughout its “sporting career,” from 2004 to the present, the flagship chassis of the Prevalle brand has been able to win more than 10 world titles and numerous victories at the international level. The desire to continue this path studded with victories also with the new “T” version, has led the R&D team of the OTK Kart Group to introduce several innovations for 2025.

RENEWED LOOK, HIGHEST EFFICIENCY

M11 Bodywork Kit
The quest for an ever-increasing aerodynamic efficiency led OTK’s R&D department to develop the new M11 Nassa Panel and Nose Cone kit. Extensive wind tunnel testing and on track testing together with highly advanced CFD computerized simulations have led to the birth of the new Nose Cone and Nassa Panel with unique designs that guarantee a substantial reduction in aerodynamic drag, resulting in better performance on track. The side pods and rear bumper remain unchanged. The full coverage floor tray maximizes aerodynamic efficiency and further reduces lap times. A newly design sticker kit gives the 2025 model the last finishing touch of perfection.

INNOVATION FOR DIRECT DRIVE CLASSES

BWD Braking System
Among the main novelties introduced by OTK in 2025 is the new BWD braking system, reserved for Direct Drive classes and it is a real winner. The highest quality raw materials ensures the highest degree of component efficiency. The unprecedented concept behind the project has resulted in a braking system able of highly improving heat dissipation, consequently reducing the temperature of the brake fluid – this ensures fully efficient braking consistency over time and in all track conditions. IKD imports all our karts with the larger 206mm disc for the ultimate braking performance.

CUTOMIZED DRIVING POSITION

Pedals and Steering Wheel
Multi-adjustable pedals and the inclined steering wheel hub guarantee the driver can tailor make his/her own driving position. The HGS (high grip) steering wheel with its rubber handgrip significantly improves driver comfort even further.
