Looking at the chassis drawings, can you tell if they correspond to the kart models that we indicate to you?

The chassis in the drawing is not the Birel Torsion but the Pulsar, a chassis manufactured by Haase Kart and was approved in 1997. It features an unconventional front end design as explained in the First analysis article we dedicated to it. The most interesting part of the frame is the crossing of the longerons in front of the fuel tank where the left longeron passes under the right one. The production of the chassis generated several difficulties, especially when seen in light of the machinery available at the time, which was undoubtedly less technological than the machinery available today. The tubes of the Pulsar are 32mm in diameter, except for the two tubes which join the longerons in the front, having diameters of 28, 30 and 32mm, depending on the track where the chassis was used.
