C = Cadet
CCD = Cadet Cut Down (Lower Back)
XS = X-Small
XSCD = X-Small Cut Down (Lower Back)
S = Small
SCD = Small Cut Down (Lower Back)
MAN = Manetti
MS = Medium Small
ML = Medium Large
L = Large
XL = X-Large
This goes Standard, T (TonyKart), VG, VTI in softness levels. The T is the rigidity of the original TonyKart seats which is more closer to a standard then a VG. Most people replace their original seats with a VG in a TonyKart to give more movement in the corners and it's also more easy on your ribs. The VTI is common in cadet classes and comes as standard on a Synergy.
Tillet T5 Seat Information
The fully covered T5 is developed from the Original 'Tillett' seat in 1990 and was the first kart seat to ever feature the now familiar "flat bottom". The flat bottom is set at 63 degrees, which helps achieve a low centre of gravity whilst still retaining the more upright driving position. In this seat your head will be 2 cm lower than when measured in a T10.
The fixed cover with integral padding makes the seat super comfortable and stops the driver from sliding around during cornering.
This was the seat used by Wade Cunningham to win the 2003 World Championship at Sarno.
Unlike the fully covered T5, the T5 Reverse has a smooth inside, this allows uncovered 1/4 and ½ covered seats to be produced in the popular T5 shape. The XScd T5 Rev size is popular with the 10 to 11 year old Cadet/Mini kart drivers and now there is also a new C size available for tall thin Cadets and a Ccd T5 for the shorter cadet driver who wants to use a flat bottomed seat.
Because it was made off the back of the T5 moulds, equivalent size T5 Reverse seats will be slightly larger than the standard T5 moulding. For example; the size of a ML T5 Reverse falls in between the ML and L sizes in other shapes. Drivers with wide hips often prefer the T5 Reverse shape.
Tillet T8 Seat Information
The T8 and T8 1/4 are the most popular seats made by Tillett Racing Seats. The shape of the T8 is very similar to that of the T7; both have the same 63 degree driving angle and the same excellent comfort and depth. The only difference between the two shapes is that the T8 is slightly smaller at the top and slightly bigger at the bottom. The T8 was the first kart seat to be made using the RTM production method. This system makes strong fibreglass mouldings with uniform quality and thickness, the process also speeds up production, keeping the T8 price below that of the handmade models. There are two rigidity options Standard and Soft.
The composite quality of the T8 is perfect and the two smooth sides keep a clean professional image throughout the life of the seat. The T8 can be ordered uncovered, with a 1/4 or 1/2 partial cover or a full cover. New for 2012 are the white and silver options. From January 2012 all covered seats will use the white, silver or black fibre. The clear seats will not be used for covered seats as the adhesive shows through the translucent part. All Soft T8 seats are white fibre. The uncovered clear T8 remains to provide a low cost seat option.
Tillet T10 Seat Information
The T10 is the seat that was used to win the 2011 and 2010 CIK FIA World Championship and it also won 2010 CIK FIA World under 18 Championship.
The T10 avoids positioning problems that can occur in some types of chassis. Fixed front seat stays sometimes limit the space for the seat. When moving the seat a long way forward, (e.g. when there is exceptional grip at the rear) the seat will rise up on the front stays as it's pushed forward, therefore making it impossible to mount the seat forward and low. The T10 has a smaller dimension A, than our other types, thus allowing dimension B to be large enough to allow the weight to be distributed correctly for the conditions or chassis type. This seat would be popular in classes where the engine is heavy and there is a need to take the weight off the rear.
The T10 also has one of the most extensive size ranges and includes a very good set of sizes for juniors, the C, XScd, Scd and S being particularly popular.
Tillet T11 Seat Information
The T11 is the seat most often used by the professional teams. With young drivers growing ever taller, there was a need to lower the body weight. We designed the T11 range to obtain an even lower driving position than the T5, whilst at the same time keeping an upright shoulder position which allows the drivers to retain full control of their karts without upsetting the weight distribution through the corners. The flat area on the bottom of the seat is larger than the T5 and the back angle has been changed to 58 degrees. All the usual rigidity specifications are available in the T11 and these options are also mostly available in the lightweight carbon Kevlar versions.
Tillet T12 Seat Information
The perfectly moulded T12 seat is based on the T11 shape but is made by injection, which keeps the quality higher and the cost lower. The mechanised method of production replicates the rigidity and shape accurately every time, which means that the handling will be totally predictable. The two smooth sides of the T12 seat will keep a clean professional look throughout its life.
The T12 has two rigidity options; Standard or Soft. The T12 Soft will give a little more diagonal flex in the chassis.
The T12 has a 58 degree back angle and a large flat area for a very low driving position. The size range is as Follows; S, Manetti MS, ML, L and XL.
For special wider top sizes and smaller seats in the same shape please see the T11 range.
Measuring the head is a starting point for the entire sizing procedure. Due to varying shapes, heads that are apparently the same size when measured by a tape may not necessarily fit the same size helmet. The circumference of the head should be measured at a point approximately two centimeters above the eyebrows in front and at a point in the back of the head that results in the largest possible measurement. Take several measurements to make sure you have the largest one.
