Chassis Kosmic Mercury T - OK OKJ BWD 2026 !!

Kosmic Mercury T – OK Chassis

The Kosmic Mercury T – OK represents the reference chassis of the Kosmic Kart range for the Direct Drive categories, combining design continuity, advanced technical development and a winning DNA built in the most important international competitions.

The chassis is entirely manufactured from Ø 30 mm chrome-molybdenum steel tubing, featuring a proven and unchanged geometry that ensures balance, structural rigidity and driving precision. It offers extensive setup options: ride height adjustment, stiffness tuning via the front torsion bar, and a wide range of camber and caster adjustments, thanks to multi-hole eccentric inserts with integrated uniball.

Winning tradition and continuous development

The Mercury has always been one of the iconic models in Kosmic Kart history, achieving numerous international successes. The “T” version is the result of continuous development carried out by the OTK Kart Group R&D department in close cooperation with the Kosmic Kart Racing Team, preserving the core principles of the project: top-quality materials, advanced manufacturing processes and constant development based on data gathered on track.

M11 bodywork kit – Advanced aerodynamic efficiency

The Kosmic Mercury T – OK is equipped with the M11 bodywork kit, developed through CFD simulations and wind tunnel testing. The new M11 front number panel and M11 front spoiler deliver a significant reduction in aerodynamic drag, improving speed, stability and overall performance, especially on fast circuits.
The aerodynamic package is completed by M10 side pods and rear protection, along with the full-coverage floor tray, which reduces air turbulence in the front area of the chassis and further enhances aerodynamic efficiency. The whole assembly is finished with renewed graphics, modern and aggressive, fully aligned with Kosmic Kart identity.

BWD braking system – Racing performance for OK classes

For the OK category, the Mercury T is fitted with the new BWD braking system, specifically developed for Direct Drive classes. The one-piece forged rear caliper operates with two Ø 34.5 mm pistons featuring automatic stroke recovery and is combined with upgraded brake lines and DOT 5.1 brake fluid.
Calipers and master cylinder are manufactured from Ergal, selected for its excellent mechanical properties and further enhanced by hard anodizing, which reduces wear of moving components and ensures consistent braking performance even under extreme conditions. The system is available with a 180 mm or 206 mm rear brake disc.

Tailored driving position

The chassis retains the OTK multi-adjustable aluminium pedals and the angled steering hub, allowing precise customization of the driving position. The HGS steering wheel, with its high-grip rubber coating, improves comfort and control while reducing driver fatigue.
