DIET, EVERYONE!

Weight reduction not only represents a way to increase the performance of a kart, but above all to improve safety. We have carefully analyzed the current situation and have discovered that something can be done. The direct drive classes are where there is more of a margin to this regard.

HYPOTHESIS: REDUCING THE KART’S MINIMUM WEIGHT

Safety is a subject dear to all fans of motorsport, especially when it concerns hermeneutical categories and, in this, karting is no exception. The kart is a simple vehicle and, at least originally, extremely light. A 100 cc before the advent of the fairings weighed only 50 kg which, combined with a theoretical weight of 75 kg of the driver, determined a minimum weight of 125 kg. Then, over time, the fairings came: an accessory that drastically improved the passive safety of our vehicles, which implied a weight increase of 5 kg (perhaps too many, with hindsight). Going forward with the years, other mandatory accessories have arrived (nose cone, electric starter, etc …) that have brought the weight ever higher. Obviously, a vehicle born without a roll-bar, in the event of a rollover, is more dangerous if it is heavier. And let’s not be fooled by superficial evaluations: 10 kg at over 130 km / h increase exponentially to touch a theoretical value of about 100 kg, destined to increase further if you are in a curve. That said, it is clear that a reduction in weight is a goal to be pursued in the name of safety, especially if the vast majority of drivers are forced to load a lot of ballast to reach the minimum value. If then the performance should increase too much, there is always a way to limit the power of the engines, especially if some propedeutic categories are faster than the professional ones (think OKJ compared to OK), but this would be a secondary aspect to be evaluated later.
