TONY KART UNVEILS THE RACER 401 RR AND THE 2022 LINE
The latest evolution of the top chassis from OTK Kart Group has been presented, twice world champion in 2021. As for the mini category, the range expands with the new rookie EVS.
Racer 401 RR, Rookie EVH and Rookie EVS: these are the names of the latest evolutions of the Tony Kart chassis. For more than 20 years, the racer has embodied the winning spirit of Tony Kart and is the focal point of the entire range: born in 2000, it has collected 10 world championships - including the two most recent 2021 titles, in both the KZ and OK classes - apart from several international victories in all categories.
As always, our Tony Kart Racing Team plays a key role in the developments introduced: the constant work of the R&D department of the OTK Kart Group is "guided" by the information collected by the official racing department on the most important circuits in the world. And above all, the track experience has led to the second big news for the 2022 season, the renewed Rookie, now called Rookie EVH, flanked by a second model (always for the Mini class), the Rookie EVS.
WIND-CUT AERODYNAMICS
Thanks to thorough wind tunnel tests and CFD computer simulations, the R&D department of OTK Kart Group has developed the M10 kit for the Racer 401 RR, which includes slimmer side bumpers with reduced weight and able to favor cooling of the rear tires. The front nose and M7 number plate (now in green) comply with current FIA regulations, as does the rear protection, which is now adjustable in width.
MAXIMUM COMFORT ON THE TRAIL
The Racer 401 RR sees the introduction of further refinements in terms of driving position, with the possibility 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.

NEW FOR THE TRANSMISSION VERSIONS
In the braking area we find the proven BSD system for the single speed versions and the BSS for the geared and DD2 versions of the Racer 401 RR. The braking systems are the same ones fitted to the OK and KZ classes by the Tony Kart winners in the 2021 editions of the FIA ​​World Kart Championship. Alongside these technical solutions, there is the new BSZ braking system, dedicated exclusively to the geared versions and equipped with brake pumps with larger-diameter pistons for perfect braking adjustability.
TWO ROOKIE MODELS
There will be two chassis in the Mini category: the Rookie EVH and the Rookie EVS; The latter features a revised frame in terms of geometry, better suited to "soft" tire compounds. Both mini chassis are equipped with a floating disc and adopt the renewed graphics of the top model Racer 401 RR.
Unchanged for the entire range, the philosophy "Designed, Engineered, Manufactured, 100% made in OTK - Italy", 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.
