NEW 2017 EXPRIT KART: CONTINUOUS IMPROVEMENT

NOESIS S and THOOS S. These are the names of the 2017 Exprit chassis for non-shifter and shifter classes, the results not of a drastic departure from previous models, but of a steady improvement thanks to the adoption of new machinery on the OTK production line.

The Noesis S has a frame made of 30 mm diameter chromium molybdenum steel tubes, while the other one uses 32 mm tubes. However, both have the option of modifying the height of both the front and rear ends, as well as the camber and caster adjustment system using multi-hole eccentric bushings with built-in uniball. Both frames also feature developments concerning the attachments of the steering column support and the front bumper attachment, while the central flange is forged and specifically designed for the silencers of the new OKJ and OK engines.

In general, the improvements made on the 2017 chassis have focussed on decreasing the overall weight, which is of vital importance when deciding where best to locate any weight boxes required to reach the minimum weight limit. A particular mention goes to the new 1.5 mm thickness floor tray and the single-piece chain guard support made of a new, lighter material. The accelerator cable register and the gearwheel support hub, now fitted with two screws, are also new.

The most significant difference between the two chassis is the shape of the frame, with the one developed for the KZ class designed to adapt effectively to the larger engine size. In light of this, for example, the seat support attachments have been modified to allow the engine to sit perfectly.
