Robotised welding using the latest machinery; continuous checking of the geometries of each frame; sample quality control of every detail. A total of 115 changes from the first Sigma model to the current one... Goal: maximum performance on the qualifying lap and in the race, for the flagship chassis of the French Sodikart company.
The Sigma chassis is the top model in the Sodikart range; the most successful by the French manufacturer, but also, in recent years, among the most competitive on the international shifter kart scene. The Sigma has a long history and the new 2018 approval does not include any major upgrades, but the changes add to the continuous evolutions performed over time, with the aim of remaining at the top of the class. Sodikart’s main goal has always been to offer a package with a basic set-up suited to almost all circuits and conditions, with the opportunity to make small adjustments that can have a significant impact on the chassis. Moreover, in this latest version of the chassis, a lot of work was done regarding reliability, a key aspect in races, when it is crucial to maintain maximum performance right up to the last lap.
The chassis has a traditional shape, even if it is wider in the central part where the two parallel tubes pass from the rear axle to the front axle. The automated welding adopted by Sodikart in recent years are excellent in mass production to obtain high and consistent levels of quality.
