Following the new homologation (2018-2020) for chassis, fairing and braking systems, CRG has introduced several technical innovations.
As the homologation works regarding chassis, braking systems and fairings for the next three years (2018-2020) have reached their conclusion, CRG has officially introduced its new Racing range for season 2018.
The new chassis will be available through the CRG sales network in the next few days and the main teams connected to CRG are already testing the material on track to allow their drivers to prepare the next racing season.
A lot of innovations have been introduced, both regarding technical solutions and design. Design-wise, CRG had already previewed the attractive new look of the chassis (that will be customizable with the name of the driver) and the new stickers kit that will be standard on all products.
From a technical side, the main novelty is the introduction of two new chassis for direct drive classes: the 30mm and 32mm KT4 models and the Heron 30mm chassis featuring a special geometry.
Regarding KZ, the successful Road Rebel has been updated with some technical interventions to make it use more effectively the tyres employed in the main KZ classes. An important work has also involved braking systems with the adoption of new discs and pads, while fairings and holders have been updated to provide important weight improvements. The whole range is fitted with new steering wheels, that have a diameter of 340mm and lifted spokes that allow an higher grip.
The most significant novelties follow.
KZ CHASSIS. The center of gravity of the successful model Road Rebel has been modified in function of the tyres used in the main KZ categories, which improved cornering, braking and traction. Performance has also been optimized by a slight change in the rear track. All KZ models of this range feature magnesium R-line hubs and spindles, magnesium wheels and new VEN 11 KZ braking systems.
DIRECT DRIVE CHASSIS. The model KT2 with 30mm tubes is the reference point for direct drive chassis that have specifically designed for OK and for the main single make Trophies. No real big change has been made to the chassis. Models KT4 and Heron are a novelty instead. The first has a 30mm tubing and 32mm crossbeams and front end tubing. The geometry of the central part of the chassis converges to the middle, and the convergence becomes more pronounced in correspondence of the fuel tank. The HERON model takes up the concepts of a CRG chassis used back in the 90s revisiting it with the current technology. This model has a particular chassis layout featuring the central crossbeam fused with the front end. All models fit magnesium R-line hubs and spindles, magnesium wheels and new VEN 11 DD braking systems.
KZ BRAKING SYSTEMS. Starting from 2018, KZ braking systems produced by CRG will be identified by the code VEN 11 KZ. Break calipers have not undergone big modifications, compared to the previous homologation, but discs, front and rear pads have been updated significantly. The external diameter of the cast iron, self-venting disc that was previously daisy-shaped has now become linear, and the section of the cooling holes has been changed too. The diameter of the rear disc has been raised from the previous 189mm to 192mm, while the diameter of front discs has gone up to 154mm from the previous 150mm. The new brake pads will be orange instead of red. These interventions produced a more effective braking, a more homogeneous wear of pads which turn in a better feeling with the brake pedal for the driver.
DIRECT DRIVE BRAKING SYSTEMS (OK). Braking systems for direct drive categories will be identified by the code VEN 11 DD. These are identical to the KZ rear braking system, with all the novelties in terms of disc shape and orange pads. The most important update for the direct drive categories is the optional choice of a smaller disc. This new element is still cast iron and self-venting, but has a 181mm diameter instead of the standard 192mm and is thinner. The benefit of this solution is a reduction of the spinning mass, especially in Junior classes that have lower power, with a better modulation of the braking force. A specific adaptation kit has been devised to fit this disc, which includes hubs and specific supports for the brake caliper and slightly bigger pads.
FAIRINGS. The biggest change regarding the newly homologated fairings is at the front end, that has been updated with a new layout in the central part and made wider. This is to improve the drag coefficient and to provide more safety. The front steel bumper has also been updated in its top and lateral parts and has been made a lot lighter. The front number holder has also been slightly changed, while the supports of the side pods have been modified to achieve a big weight reduction.
