To correctly install your new Tillett seat use the Kartech Seat Bolt Kit
The T5 is the seat shape most often used by the Cadet drivers in the age group 8 to 12. The T5 has a small flat but is deliberately not made with the T11 angle as the small children need a more upright body position for greater strength and control.
The moulding technique that makes these seats has allowed us to make a smooth front and back surface with a consistent laminate thickness The T5 benefits from a specially developed high strength resin and contains a much higher fibre content than hand laminated seats which makes it more robust during drilling and impacts with the track.
The super flexible VTi is most often used in the two stroke Cadet classes.
