Tillet seat T11 standard rigidity (12 x sizes)

The T11STD ("STD" - Standard rigidity) is the most rigid seat in the T11 range. The Standard Rigidity was the standard stiffness for many years but has become the most rigid seat in the Tillett range. Although the flexible options are more popular some require "Standard Rigidity" to balance their chassis. The more rigid "Standard" seats are also still used in 4-stroke classes where the engine provides ample torque and kart types where rigidity is not a factor.

The Tillett "T11" kart seat is a World Championship winning product. The T11 shape is the most popular for adult sized karts, typically used by manufacturers and professional kart racing teams. The T11 seat model range has a flat base and a 58°/mid-angle reclined back. The design was created to position the driver lower in the kart whilst allowing a more powerful upright shoulder turn, giving the driver more control. Deep sides give ultimate support and reduce the risk of rib injuries. All Tillett kart seats are made in the UK from high impact resistant, strong fibreglass, using Tillett's unique manufacturing process that guarantees perfect control of rigidity.

"STD" (Standard) is one of four rigidities in the Tillett range
