CIK-FIA 2014 – 2020

The homologation of the CRG Road Rebel expires in 2020. It’s valid for all categories.

KZ – KZ2

The Road Rebel was developed for the KZ category, even if the homologation of the chassis is valid for use with both non-shifter and shifter engines.


Generally, tubes going from 30 to 32 mm are used. The CRG Road Rebel only has 32mm tubes.


There are two “schools of thought”: either manual or with welding robots. CRG uses welding robots.


Standard accessories for the racing chassis are in magnesium, but, on request, they’re also available in aluminum.

The Road Rebel, the approval of which expires in 2020, is CRG's flagship chassis in the shifter classes and the winner of numerous titles in recent years. In the 2019 season, the kart benefitted from several upgrades on the previous model: the main one concerned the axle support box section that allows variations to the wheelbase. However, the restyling of the graphics is the most visible

The research and development of a kart chassis is a continuous endeavour, especially for a company such as CRG, which uses its participation in competition as the main test bench to through which to guide the evolution of its racing products. This is confirmed by the 2019-2020 version of the Road Rebel, subjected to careful updating that has renewed certain important aspects. Starting with the significant amount of work concerning the material of the chassis tubes: chrome molybdenum steel, whose characteristics, especially its hardness, influence chassis flex. However, the main structural innovation was introduced during 2019 half season at the rear end, introducing a new box section that allows variations of the wheelbase in just a few steps. The axle bearing flange, which can be mounted centrally (standard position) and can be varied in height up to 5 mm upwards and 5 mm downwards, can be moved towards the front or rear by loosening the four fixing screws and modifying the wheelbase according to the set-up required. Horizontal movement can also be varied +/- 5 mm from the standard neutral position. This is done by rotating the flange: a procedure that requires little time and does not require axle disassembly.

The CRG Road Rebel mounts the VEN 11 KZ braking system: compared to the previous VEN 10 version, there are new brake discs with a different diameter and thickness, as well as new pads that are better suited to them. The brakes also have a new feature concerning the brake distributor, whose adjustment cog moves in steps: this helps drivers, who can count the number of clicks so that they know the distribution between front and rear. As for the accessories, 2019 saw the introduction of a new stub axle called RX2, which differs from the standard model due to the dual holes used to adjust the Ackermann angle. There are also changes to the aesthetics: at the 2019 KZ and KZ2 World Championship at South Garda Karting in Lonato (Italy), CRG unveiled a restyling of the graphics, in which the characteristic orange colour is treated to a glossier finish. The change in design especially concern the lower part of the front number fairing, resulting in a cleaner front end of the kart that is easily recognisable on the track. The black colour of the frame is unchanged, with a beautiful matt finish created directly by CRG in its advanced paint department. However, nothing was done regarding the design of the frame, given the expiry date of the approval in 2020.
