- December 2019 update -
CRG Heron is ready to take on its last year of homologation, which expires in 2020, with several updates. Although the distinctive design of the frame has remained unchanged, as per regulations, the situation is quite different for the bearing housing in the rear axle, innovated with the introduction of a system that allows the wheelbase of the kart to be varied in just a few simple steps.
A chassis homologation is valid for 3 years. During these three years substantial modifications cannot be implemented to the design of the frame, yet this does not affect the changes that, from year to year, can be made with the purpose of improving its performance on the track. The development of a chassis, basically, never stops, as demonstrated by the 2020 version of the Heron chassis, on which the CRG technicians have introduced an interesting new feature at the rear: a completely revised bearing housing that allows to adjust the kart’s wheelbase.
The system works through a new axle bearing flange that, in addition to be able to have its height changed on three different positions (standard central, 5 mm higher and 5 mm lower) by loosening the four fastening screws, it can also be moved to the front or rear of the kart by shortening or lengthening the kart’s wheelbase accordingly, depending on the setup change one is looking for.
