Engines used within
the class are identical, apart from a capacity
change between Junior
123/128/135/142 (100cc) and the
(115cc) classes. Virtually no modifications are
allowed and real tight rules ensure a level playing
field for everyone.
Karts no longer have to be TKM homologated, but still
have some rules that keep costs down and chassis set
up simple compared to other classes.
The result has been tremendous stability in the
class combined with superbly close racing making the
formula the backbone of the sport for newcomers and
potential F1 stars alike. By placing the accent on
driver ability rather than cheque-book it helps to
identify the very best driving talent.
Tal-Ko has played a key role in maintaining the
stability and strength of the class while at the
same time moving it forwards with innovations such
as the TKM Festival – the largest single formula
event there is. There have been technical
innovations too with the development of the Horstman
optional clutch model engine with remote F1 like
electric starter system and new in 2009 the exciting
TAG, Touch & Go on board starter engine option.
With three classes covering every age and size range
from 11yrs to 60+, Formula TKM offers incredible
value racing for drivers of every type and budget.
It is easy and
inexpensive to transfer from one class to another so
you can grow with your kart without the need to sell
the equipment and start again.
each Junior weight
transfer takes just moments
changing to a different carb
The 148 Kilo Junior band runs without a carb air
restrictor. The transfer to Senior Extreme
from Juniors requires an engine bore
to increase capacity from 100cc
- normally carried out as part
of a standard routine rebuild. Senior Extreme is now
divided into 2 weight bands:- 152 Kilo without carb
air restrictor and 146 Kilo using the Blue carb air
restrictor. There is also a Senior Extreme
Clubman class for drivers over the age of 35 yrs
with a 165 Kilo limit.
