OKR AND KZR. THE BRAKE SYSTEMS FOR OK AND KZ DESIGNED BY K-KART

K-Kart may not be one of the most known names in the world of karting, but, in reality, it is a company which can boast itself as an organization with excellent and established experience, while over the years it has enabled them to conquer important positions in the marketplace and to be highly considered by karting enthusiasts. Founded in 1992 with headquarters in the city of Lučenec, in the south-central region of Slovakia, the company is the result of the Konopka brothers’ passion and experience. Its field of expertise is that of karting accessories, from sprockets and gear systems for the wheels to bearing carriers, hubs, axles and tire rims (in aluminum and magnesium). They also have, of course, discs and brake systems as well.
In the last homologation session, valid for the 2018 - 2020 periods, K-Kart presented two brake systems models: OKR and KZR respectively dedicated, as perceived by the name, to the single-speed and the shifter karts classes.
K-Kart products are chosen by different manufacturers to equip their karts, above all the Czech MS Kart, but also the Italian companies TB Kart and SRK.

The new 2018 homologation models have been perfected in an important number of different aspects. The first aim was a greater modularity for the system, a key feature for the use on karts where an extremely aggressive system may break down the chassis, especially in the case of less experienced drivers. To obtain this result, a 30 mm diameter double piston was used on the rear caliper, while additional options and calibrations derived from the two rear discs, both self-ventilated while being drilled, with slight differences regarding the superficial machining. The dimensions vary: 15 mm in thickness and 181,5 in diameter for the first model and 17 mm with 192,5 diameter for the second. The system differs also in the internal and external diameters in the area of contact of the brake pads on the disc.
Clearly, for the KZ version, the system is equipped with front calipers. Here, the single piston has a diameter of 25 mm while the disc, self-ventilated and drilled, has a thickness of 12 mm and an external diameter of 157 mm.
