Tillett T11 VTI Seat (Various Variants)

The T11 is the most popular adult form and is the most widely used by professional kart teams and manufacturers. With each generation getting bigger, a new seat was needed. A large flat area on the base was created and combined with a more reclined back angle of 58°, significantly lowering head height. Although lower body weight provides a performance advantage, it is important to maintain an upright shoulder position so that sufficient power can be transferred to the steering wheel. If the driver leans back too far, there is a high chance of “pulling to steer”, which is bad for controllability and body stability. The T11 shape allows the right angle of the upper body to maintain firm control and hence performance.
