THE TOP OF THE RANGE MODEL
Tony Kart Racer 401 RR
The latest evolution of the top-range chassis of OTK Kart Group has been introduced, twice world champion in 2021
|
WIND-CARVED AERODYNAMICS Thanks to the in-depth tests sessions carried out in the wind tunnel and by means of CFD computer simulations, OTK Kart Group's R&D department has developed the M10 kit for the Racer 401 RR, which includes slimmer side bumpers with reduced weight and able to favour the cooling of the rear tyres. The front nose and the M7 number plate (now in green) comply with the current FIA regulations as well as the rear protection, now adjustable in width. |
HIGHEST COMFORT ON TRACK The Racer 401 RR sees the introduction of further refinements with regard to the driving position, with the chance now of adjusting the footrest more flexibly and thanks to the introduction of new seat supports. All this, as always, combined with the HGS steering wheel and its inclined hub. |

NEWS FOR THE SHIFTER VERSIONS As for the brakes, we find the tested BSD system for the single-speed versions and the BSS for the shifter chassis and DD2 versions of the Racer 401 RR. The braking systems are the same ones that equipped the Tony Kart winners in the 2021 editions of the FIA Karting World Championship for OK and KZ classes. Next to these technical solutions are the new BSZ braking system, exclusively dedicated to the shifter versions, equipped with brake pumps with larger diameter pistons for a perfect braking adjustability. Unchanged, for the whole range, the "Designed, Engineered, Manufactured, 100% made in OTK - Italy" philosophy, at the base of all products signed by OTK Kart Group. The Italian company has always used only selected and quality-controlled materials, processed through automated processes that guarantee uncompromising production standards. |
