Currently the T14 is only available in the smaller Cadet/Minikart sizes, Mini, Ccd, CL and XScd. The reason for only having four small sizes is that older juniors and adults are typically strong enough and bracing with the legs is not necessary. The extra width of the leg support can also be a problem with adult sizes, as it miss-aligns the sensitive airbox on many engine combinations. However, the added support can be ideal for classes where a particularly small or inexperienced driver struggles to control a faster kart. T14VTI is what we call a soft rigidity seat. The VTI rigidity offers more rear wheel from stiffer seat models. Typically, we find the VTI seats are popular because of their level of flexibility.
