The seat is one of the most important elements to define the best driving position, as well as having a fundamental role in the balance of the kart. In this case too, the choice of the seat model varies according to the preferences of the driver, yet what does not change is checking the space at the height of the rib protector to get a seat of the right size. It is necessary to avoid for the seat to be too wide so as not to have too much lateral movement while, at the same time, a seat that is too narrow would drastically decrease the driving comfort. As a practical reference, we can say that when you try a new seat, without a suit and rib protector, you need about 1.5 cm of space on the right and left sides, a necessary measure to be able to wear a suit and rib protector with the relative pads to cover the bolts. Of course, the size varies depending on the model of rib protector and whether or not the sponges are inserted on the sides of the seat.
To ensure the correct use of the rib protector, it is essential to choose the right size. Simply measure the chest just below the nipples, check the measurement on the manufacturer’s size chart and proceed to the purchase. If the purchase takes place in the store, you can try it on and remove any doubts. Be careful, though, as drivers often make the mistake of trying the rib protector while standing, which does not provide the correct fit. The rib protector should be tested while sitting, even better if in the driving position so as to adjust the straps and the closure in the exact way to check the size. Some drivers prefer to eliminate the shoulder straps, a solution that we at Bengio do not recommend, as the straps allow the rib protector to remain in the position defined at the start. Without them, the protector tends to slide and, if the seat is slightly wider, it can rotate especially when driving a KZ kart where the driver moves his arm to change gears.
