THE TOP OF THE RANGE MODEL
This is the latest and most refined evolution of the RX R. With a new livery but unchanged chassis geometry, it is made with Ø 30 mm chrome molybdenum tubing. The ‘R’ represents the continuing series of technical evolution developed by the Research and Development Department of the OTK Kart Group.
A Winning Tradition
20 YEARS AT THE TOP OF WORLD KARTING
The new RX R continues OTK’s success story, improving various features but most notably the level of componentry. Among the new innovations, the new ‘high-grip’ steering wheel with an inclined steering hub boss, the integrated enclosed frontal area with the new M7 Series front spoiler and newly designed graphics. Remaining unchanged though, is the chassis geometry and design. Just as the cornerstones of philosophy, the base of the project do not change; highest quality materials, technologically advanced processes, and constant development carried out and developed by the OTK Racing Teams at the most important races around the world.
BSD Brake Caliper
RACING TEAM GUARANTEED’ PERFORMANCE
For the direct-drive categories, the RX R is equipped with the successful BSD braking system. The rear brake caliper has been forged from a single piece, has two 34.5 mm pistons inside with brake movement recovery, and is combined with evolution brake lines and DOT 5.1 brake fluid. The calipers and master cylinders are made from Ergal (7075 aluminum alloy) material, chosen for it’s notable property of mechanical resistance and is in turn improved by a hardening and thickening oxidation process which serves to minimize the wear on moving components. The latest technical measures have been developed on track in the most competitive and prestigious races around the world. The toughest racing conditions have delivered a very high quality braking system.
AN EVOLUTION IN AERODYNAMICS
Thanks to testing carried out both in the wind tunnel and in Computational Fluid Dynamics (CFD) computer simulations, the OTK M6 was homologated in 2015 ensuring optimal airflow and functionality to the kart. Now, following on from this is the new M7 front spoiler (or Nassau panel) which further reduces aerodynamic drag, particularly on the fastest straights of the longest circuits. The M7 combines with the front fairing (front bumper) and an integrated floor plate to create a fully covered frontal area of the front chassis rails and tubing. This is a solution which improves the aerodynamic drag co-efficient and reduces the creation of air vortices in the ‘C’ section of the chassis.
New Steering Wheel
COMFORT AND SENSITIVE FEEL WHEN DRIVING
The constant improvements at the center of the daily working philosophy at the OTK Kart Group examines and improves every aspect and every single component of the kart. The RX R, in particular, sees the introduction of the new steering wheel which is a high-grip wheel that is also designed to give maximum sensitivity and feel to every driver. Complimenting the new wheel is the inclined steering wheel boss which allows the steering position to be adjusted to suit each individual driver.
Dedicated to the Gearbox Categories
IN SEARCH OF PERFECTION
The approach of the OTK Kart Group is to always use materials of the highest possible quality and use manufacturing with automated equipment to guarantee the complete replication of each item to the highest quality for a kart dedicated to the KZ categories. This is in fact, the most complete kart, to which all the main technical characteristics are also present on the OK kart, but with the addition of some specific details. For example the optimized chassis design and the BSS braking system which includes front brakes. These are characterized by single-piece calipers, equipped with 4 sets of Ø 22 mm pistons with brake movement recovery to guarantee powerful, quick, and adjustable braking.
