THE FLAGSHIP MODEL
CS55 Racing Kart dedicates the top of its range chassis, the CS55, to the single-speed, shifter and DD2 categories. At the end of the development work of the OTK Kart Group R&D department, the new CS55 features some interesting technical solutions.
The circle closes
A WINNING PARTNERSHIP
The partnership between OTK Kart Group and Carlos Sainz, driver of the Formula 1, is the story of a circle that closes. The new chassis range has been created with the aim of inspiring and motivating a new generation of young and talented drivers. And to do so, the new CS55 keeps faith with the company mission "Designed, Engineered, Manufactured, 100% Made in OTK - Italy" at the base of all OTK Kart Group products. The rigorous control of the entire design and production chain, thanks also to the use of automated processes that guarantee extremely high-quality standards, has always been the distinctive element of the Italian company.
Fairing kit M10
SCULPTED BY THE WIND
OTK Kart Group's R&D department has been for year a pioneer in the aerodynamic research and development of its karts through wind tunnel analysis and CFD computer simulation. This relentless research activity has led, over time, to the launch of revolutionary solutions in the field of fairings such as the M7 front spoiler, with its innovative design and ability to reduce aerodynamic resistance, resulting in increased performance. The M7, made of black plastic, is now flanked by the new M10 kit for the CS55. This consists of the new side bumpers, which are lighter in weight and smaller in size, to the benefit of performance and better cooling of the rear tyres. But that's not all, because the front spoiler and rear protection have also been renewed in order to meet the increasingly demanding requirements in terms of FIA safety regulations.
BSD Caliper
TOP BRAKING SYSTEM
The CS55, in its single-speed version, is fitted with the BSD braking system. The one-piece forged rear brake caliper is equipped with a stroke recovery system and features two 34.5 mm diameter pistons. This is combined with a two-piston pump and a brake line with outer cover stainless steel braid, PTFE inner tube. The caliper and brake pump are made of Ergal, a material that stands out for its excellent mechanical strength, which is further increased by the hard oxidation process that reduces wear on the moving parts.
Driving position
COMFORT AT FIRST PLACE
Driving comfort is fundamental for the performance of every driver. This aspect plays a central role in the entire development process carried out by OTK Kart Group for the CS55 chassis, which offers several new features aimed at refining even the smallest details. To be highlighted, in fact, is the standard supply of a footrest that allows a greater range of adjustment, and, in addition, new seat supports. These solutions are in addition to the already well-known HGS steering wheel, equipped with high grip and comfort rubber grips, and the inclined hub, for a fully ergonomic driving position.
BSS and BSZ Brakes
SPECIFIC FOR THE SHITER CLASSES
OTK Kart Group produces according to well-defined standards: the use of selected materials of the highest quality and their processing using automated machines and processes that ensure full reproducibility of each component, always guaranteeing the highest quality parameters. These principles are more fundamental than ever when it comes to braking systems for shifter categories, classes in which braking capacity plays a primary role in performance. The CS55 model, proposes a new system for the shifter classes called BSZ, equipped with brake pumps with larger diameter pistons that make the braking even more modular. For the DD2 version, instead, the reference system remains the BSS only.
