KARTING IN 2007 AND THE FUTURE
15.01.2007

CIK
KF1 38bhp engine |
Karting has progressed from home made
tubular frames with lawn mower motors to factory produced
racing machines with beautiful bodywork and modern engines
with all the bells and whistles. The added weight of
the body work (safety being it's main function) saw
the 100cc traditional formulae slowly die as the new
FR125 MAX delivered not only more power but far superior
reliability thanks to modern technology and a modest
14 000 RPM limit (100cc were revving over 20 000 RPM
in latter years).
ROTAX introduced ''New Age Karting'' for the new Millennium.
Their one make series with strict control, sealed engines
and level playing field seemed to give kart racing the
lift that it needed. Many more countries became involved
and competing in the Olympic style World Finals is a
highly sought after privilege. The Euro Challenge and
Nationals in many countries are very competitive and
popular but what else has happened and where to next?
CIK / MSA
The international and national governing bodies have
played their part in these changes but this process
has been difficult and complicated.
Initially the governing bodies rejected the ROTAX New
Age concept but it soon became clear that competitors
saw the advantages. Italian manufacturer IAME (Parilla,
Komet, Sirio, etc. established in the 1960's) were the
first to copy the New Age concept with their 125cc Leopard
engine, followed by Vortex with the Rok, etc.
The CIK at one stage declared that 4-strokes would be
mandatory by 2006. Resistance from Italian engine manufacturers
and based on repair costs experienced in MotoX saw this
decision being rescinded and the CIK started looking
closely at ROTAX's success.
CIK "LONG LIFE" TAG ENGINES
The governing body is obliged to provide international
formulae that are open to all manufacturers like Formula
1 or Touring Cars. Formula Renault for example is approved
by FIA in the same way that ROTAX MAX, ROK, Biland,
etc. are approved by CIK, but there has to be open competition
in the CIK/FIA World Championship.
After several years of investigation the CIK firmed
up the rules for 2007 for the ''open'' classes. The
outline is:
- 125cc water cooled, balance shaft, electric start,
centrifugal clutch series productions based model.
Four variants of this model.
- KF1 highest performance version 16 000 RPM, 30mm
carburetors, exhaust power valve, dry clutch, about
38 BHP for World Championship
- KF2 medium performance 15 000 RPM, butterfly carburettor
diam 24, exhaust valve, countershaft, dry clutch,
about 36 BHP for European Championship
- KF3 lower performance 14 000 RPM, butterfly carburettor
diam 20, no exhaust valve, countershaft, dry clutch,
about 26 BHP for European Junior Championship
- KF4 lower performance 14 000 RPM, DellÓrto
carburettor diam 30, exhaust valve, counterhaft, dry
clutch, about 32 BHP for National Championships
All of these motors will use analogue
ignition with color coded coils for the different rev.
limits. Various engine manufacturers will be in these
classes in 2007. These include:
- MAXTER
- PCR
- IAME
- VORTEX (Not to be confused with Rok and Super Rok)
- TM
- MERLIN
- BALEN
- DINO
- VKR
ROTAX have decided to remain unchanged
with their one make formulae and clearly the MAX range
does not fit into these CIK categories. ROTAX achieve
an excellent high performance / cost balance by using
technology that has a high development cost but is reliable
and economical because of the economy of scale afforded
by this one make series. These technologies include:
- sophisticated digital ignition, no adjustments
possible
- Nikasil cylinder lining - for hard wearing properties
allowing long life
- Pneumatic powervalve - increased low speed power
- Rok and several CIK long life motors will use this
ROTAX component
- The two-speed ROTAX DD2 gives overall performance
exceeding KF1 but at a lower initial cost and much
lower running costs thanks to 13 600 RPM limit.
Next week - South Africa in 2007.
