The Tillett T11VTI is the softest seat in the T11 range, offering unmatched flexibility for drivers who need maximum chassis movement and rear-end grip. Designed with a flat base and a mid-reclined back angle, this ultra-soft seat helps position the driver lower in the kart while maintaining a strong upper body posture for precise control.

Manufactured using Tillett’s high-strength resin and industry-leading moulding process, the T11VTI is ideal for categories where increased chassis flex improves traction — especially in high-grip conditions or low torque engine classes. Its lightweight construction (approx. 900g) and refined lamination ensure top-level performance without compromising comfort or durability.

Frequently used in Rotax, OK, and KZ, the T11VTI is trusted by professional teams looking for that last edge in rear grip and chassis tuning.
