event of significant exchange rate fluctuations. A minimum of 10 motorcycles of the type and
specification to be raced must be imported into SA and be available for sale to the general
public prior to said motorcycle being raced.
c)
Where a particular brand and model of motorcycle (that complies with these regulations) is

MSA Motorcycle Racing Commission for a local homologation to allow the motorcycle to be
raced in the series. In such cases, the following shall apply:
• The importer concerned shall pay to MSA a homologation fee of R55 000 (excl. VAT),
which shall incorporate a fee towards the technical administration of the series.
• At least 50 examples of the motorcycle concerned must have been imported into SA
(proof must be submitted in this regard).
• The official importer must submit one new motorcycle, chosen by the Technical
Consultant, together with a completed homologation document supplied by MSA for
inspection.
• The homologation, or otherwise, of the relevant motorcycle shall be at the sole
discretion of the MSA Motorcycle Racing Commission.

fee paid shall be retained by MSA and the balance of the fee shall be returned to the
applicant.

providing that such exchange is made prior to official qualifying and in sufficient time to allow
the changing of said tyres.
Infringement of ANY tyre rule shall result in the offending rider, as a minimum, being excluded
from the results of the race concerned and/or sent to the back of the grid for the ensuing race,
together with the imposition of a 30 second time penalty. The penalty for more serious
infringements shall generally be a three (3) race meeting ban. Should there be less than 3 race
meetings left in the season, 60 points shall be deducted from the respective rider’s and
manufacturer’s standings.
The use of tyre warmers is allowed (refer SSR 2 B).
Any amendments/additions to these tyre rules shall be notified to affected parties by way of
an official MSA circular.
Where compounds are specified, these will be the only ones permitted.
The onus is on the rider to ensure that his/her tyres are correctly marked.

event of significant exchange rate fluctuations. A minimum of 10 motorcycles of the type and
specification to be raced must be imported into SA and be available for sale to the general
public prior to said motorcycle being raced.
c)
Where a particular brand and model of motorcycle (that complies with these regulations) is
not homologated by the FIM, the official South African importers may make application to the
MSA Motorcycle Racing Commission for a local homologation to allow the motorcycle to be
raced in the series. In such cases, the following shall apply:
• The importer concerned shall pay to MSA a homologation fee of R55 000 (excl. VAT),
which shall incorporate a fee towards the technical administration of the series.
• At least 50 examples of the motorcycle concerned must have been imported into SA
(proof must be submitted in this regard).
• The official importer must submit one new motorcycle, chosen by the Technical
Consultant, together with a completed homologation document supplied by MSA for
inspection.
• The homologation, or otherwise, of the relevant motorcycle shall be at the sole
discretion of the MSA.
• Should such an application for homologation be refused, 10% of the homologation
fee paid shall be retained by MSA and the balance of the fee shall be returned to the
applicant.
d) Any motorcycle homologated under these rules (parts a and b above) shall be allowed to
compete without time limitation subject to continued compliance with the appropriate
technical regulations and payment of the required fee to MSA by the relevant official importer

MSA will confirm the details regarding the tyres to be used via official circular and/or via the
official tyre order forms issued to riders.
Marked tyres must be used for all qualifying sessions and races. The onus is on the rider to
ensure that his/her tyres are correctly marked.
Notwithstanding the above, if a race or qualifying session is declared as "wet" by the Clerk of
the Course within the 60 minutes prior to the commencement of a qualifying session or race,
then tyres may be changed to another type approved for wet weather use, at the sole
discretion of the Technical Consultant. In the event of conditions improving, competitors may
revert to using their marked ‘dry weather’ tyres. If the practice session and qualifying session
and races are all ‘wet’ then the normal tyre quantity limitations shall be in force subject to “d)”
below. If the sessions vary between ‘wet’ and ‘dry’ then the use of tyres shall be decided upon
by the COC in consultation with the the TC.
If a competitor deems his tyre/s to be damaged and therefore unsafe to be used, then he/she
may make application to the Technical Consultant for permission to change the damaged
tyre/s. The changed tyre/s must be of the same make, type and compound as, and be of similar
wear to, the damaged tyre/s. Selection of the tyre/s to be used is at the sole discretion of the
TC. Penalties, if any, will be at the sole discretion of the Clerk of the Course.
Only homologated tyres will be permitted to be used. Any homologated tyre may be used in
the racing season during which it is homologated.
The President of the MSA Motorcycle Racing Commission, the promoter and the MSA TC, shall,
at their sole discretion, accept, rescind or decline a request for homologation of tyres. They
shall also have the overriding authority to make a ruling in respect of any dispute regarding
the eligibility of tyres.
In interpreting the use of tyres and/or the changing of tyres and/or safety matters relating to
tyres, the Technical Consultant’s decision shall be final, and binding on all parties.
Entrants are limited to the use of two (2) sets of tyres per race meeting. The same sets of tyres
must be used for the official timed qualifying session and both races.
Set 1(one) will be issued pre-marked for qualifying and race 1.
Set 2(two) will be issued pre-marked for race 2.
The Clerk of the Course, in consultation with the TC, may request the exchange of tyres
between riders providing that the tyres are of the same make, compound and size and
providing that such exchange is made prior to official qualifying and in sufficient time to allow
the changing of said tyres.
Infringement of ANY tyre rule shall result in the offending rider, as a minimum, being excluded
from the results of the race concerned and/or sent to the back of the grid for the ensuing race,
together with the imposition of a 30 second time penalty. The penalty for more serious
infringements shall generally be a three (3) race meeting ban. Should there be less than 3 race
