CRG launches the new and improved Zuera B Gold Line, the latest intepretation of its classic Road Rebel, and wins the top two spots of the KZ World Championship podium

On September 13 (2015), CRG, one of Italy’s historical manufacturers, returned to the top spot of the CIK-FIA World KZ Championship podium, on the legendary Le Mans circuit in France.
The star of this great victory was Dutch driver Jorrit Pex, who beat rivals to the finish line aboard the new Road Rebel Zuera B Gold Line kart with TM engine.

CRG’s triumphant “world campaign” was completed by the second place finish, achieved with Italian driver Paolo De Conto. This outstanding 1-2 sweep proves, beyond every reasonable doubt, that the success driven by Giancarlo Tinini is anything but happenstance. The team confirmed once more team that winning is in its DNA and the new chassis, an innovative rivisitation of a CRG classic, immediately showed its exceptional potential.

TKART wanted to uncover all the secrets behind it, so we took a trip to the CRG headquarters in Desenzano del Garda right after the World event and took a close look.

The Road Rebel is homologated for the KF4, KF3, KF2, KZ2, KZ2, and ICE categories. We focused on the model that competed in the KZ World Championship, the Road Rebel Zuera B Gold Line, where B stands for the 2015 version and its revisitation of several key aspects compared to the 2014 homologation.

    Close up of the stub axle with brake and front hub. The hub, in particular, is fruit of an innovative manufacturing process that “carves” its zone of contact with the disk in three different points. This allows for greater flexibility between the two components and frees up the rear end of the chassis - a feature that is especially important in competitive contexts, when there is a lot of grip on track from tires.

    Another absolute innovation is the small metal insert designed to be added in front of the left bearing cassette, on the caliper side. When the component is inserted and locked down, the chassis becomes more rigid and has more grip while braking. Vice versa, by removing the insert, you give the rear end greater freedom of movement.

    Like all Road Rebel “Gold Line” accessories, the steering wheel is also gold. thr new steering system features a rivisitation of the “RX geometry”, meaning the measures and angles that govern the interplay between the stub axles, the tie-rod, and the steering column lock plate. The goal was to make driving easier and reduce the impact of potential driving mistakes.

    The biggest change, though hard to see from the oustide, regards what CRG calls “RX geometry” – meaning, the angles that define the unit formed by the stub axles, the tie-rod, and the steering column lock plate. The new solution makes for easier driving and limits the impact of mistakes, like loss of time and speed. And while it was engineered to improve customers’ driving experience, it also makes life easier for expert professionals, as CRG factory driver Felice Tiene confirmed when we asked his opinion.

    The other big change that characterizes the new Road Rebel Gold Line is more visible and regards accessories, which, as the name implies, are rigorously gold in color.
    The most innovative modification regards the new hubs, now featuring a chiseled surface that dips in three spots. This change in the contact zone with the disc brake yields a more fluid interplay between hub and rim, making the rear end of the kart more responsive, especially on a track with high-grip conditions.
