Developing your own frame and improving its performance. Year on year. That is Oberon’s basic idea, so in 2018 it has not requested approval for a new chassis, but has introduced a further renewal of the Ocean
The Oberon Ocean, the 2017 version of which has already been analysed by TKART, is characterised by tubes with a diameter of 30 and 32 mm. The frame, featuring a traditional design, confirms their collaboration with Parolin Racing Kart, a company at the forefront of automated frame welding, a crucial phase that influences the performance of chassis out on the track.
The first, important new feature of the Oberon Ocean 2018 is the option of choosing from three types of tubes with different thickness ranging from 1.6 mm to 2 mm. This range allows you to completely alter the frames behaviour out on the track, making it more or less flexible, depending on the thickness. In practical terms, the customer can opt for the solution that best suits the type of tyre used and, no less important, the different quantity of rubber deposited on the tarmac of the track, thereby increasing performance.
The option of mounting two bars (front and rear) to increase the rigidity has been confirmed. The introduction of an aluminium bar with holes drilled in several areas, depending on the point at which it is attached, is of great interest since it allows the variation of the amount of chassis flex.
Confermata la possibilità di montare due barre (all’anteriore e al posteriore) per aumentare la rigidità. Interessante l’introduzione della barra in alluminio forata in più zone che, a seconda del punto in cui viene fissata, consente di variare la flessione del telaio.
A fundamental new feature of the new Oberon Ocean are the brakes (called by Oberon SB, special brakes), which are also developed by Parolin. The system, in the KZ version of the chassis, features mono-block calipers machined from solid at both the front and rear. Another difference compared to the previous kit is the radial attachment, chosen to reduce the torsion of the caliper during operation.
The pads are also new and there are two versions available: soft, for more aggressive braking, and hard, for “gentler” braking. There is also the option of mounting a soft and a hard pad on the caliper, depending on driving style.
The extensive work performed in the study and development phases has allowed Parolin Racing Kart, the manufacturer of the system, to reduce the weight by 2 Kg, to the advantage of more precise and vigorous braking.
The previous AP 01 brake system model is still available in the catalogue, as Oberon considers it important for drivers to be able to customise its frame as much as possible.
The 2018 version of the Oberon Ocean also features completely revised stub axles: the diameter increases from 8 to 10 mm and the plate is also reinforced. The changes are aimed at improving the front end of the kart and, in particular, entry into bends, which is now more precise and dynamic. Also new is the system for adjusting the geometry of the “C”s of the frame: the new eccentric kit allows the adjustment of Caster and Camber directly from the top point, without the need to use lasers. An innovative solution that, assures Oberon, maintains the precision of the regulation and speeds it up.
The standard floor tray is still made of aluminium, but Oberon has added two new optional versions: fibreglass and carbon fibre. As for the frame, the three options offer a greater opportunity to vary the rigidity of the kart, in order to adapt the kart to the different conditions of grip.
Lastly, the steering wheel is also new, with the decision to opt for the M5 model by KG (already analysed by TKART in this article)
