1. General rules for Classic
Road-Racing, Competition, Parading and Track meetings.
* see SVEMO’s
(
1.0.
Generally: Machines are to be factory racers, production racers
or machines built to resemble racers from the actual period.
Clarification of point 1.0.: A machine
in the class <48 is to look like a racer from before
The year of manufacture of the motorcycle
shall primarily determine which class the machine shall belong to. A motorcycle
that already fits in to a certain class should not be changed in order to fit
in to another class. This is especially important for production racers and
factory racers because of their historical value. It is allowed to use newly manufactured
frames to old specifications and to modify OEM produced frames. It is allowed
to combine period frames and engines even though the combination is not proved
to have existed.
The machine shall be prepared to a high standard
with regard to safety and appearance, to achieve the machine licence. If the
machine is regarded not to meet an accepted standard, the machine licence will
not be issued or an existing licence may be recalled until an acceptable
standard can be proved.
Advice: If you are
uncertain on how to understand the rules please contact the “Machine committee”
for advice before buying, constructing or modifying your machine.
Note! At speed competitions also the SVEMO’s
competition rules shall apply. The details below must be fulfilled. Equipment
like helmet, leather suit and so on must be inspected and approved in the scrutineering.
1.1. To
participate in speed competition only competition licence is required. For
parading, run in connection with a competition event, an ordinary street rider
licence is required.
1.2. Helmet:
To be approved in accordance with recognised Scandinavian or European
standard. “Pudding basin” type helmet will not be approved. Helmets made from
polycarbonate, lexan or similar material shall not be
painted. The helmet shall be faultless without damage. The scrutinizer shall
disapprove (or even confiscate for the event) helmets that do not fulfil the
requirements. Helmets with flip-up front (type BMW) are not allowed.
1.3. Leather
suit: One-piece or two-piece leathers can be used. One-piece leathers are
recommended. The suit shall be of good quality. Back protector must be used.
1.4. Boots: Are to be
of suitable type for motorcycle riding. Moto cross boots are not to be used.
1.5. Gloves:
Only leather gloves will be approved.

1.7.
Appearance: The machines shall be painted in a pattern typical
for the time frame. That means no lightning or graffiti type painting. Decals
that were unknown within the period should not be used. Decals from sponsors
are accepted.
1.8. Oil plugs and hoses: Oil plugs or bolts that may cause oil
leakage if loosening is to be safety wired to a solid part of the motor or gear
box (not to an exhaust pipe or other parts prone to vibration). The safety wire
shall be annealed stainless steel, minimum Ø
1.9. Machines
shall be prepared for racing. Side stand and start lever shall be removed.

1.10. A guard must be fitted in such a
way as to prevent trapping between the
lower drive chain run and the final drive sprocket at the rear wheel. See picture |

1.11 Other: Definition
of a machine’s year of manufacture: Year of manufacture is regarded as the
latest year of production for motor or frame. If important items (i.e. wheels,
front fork etc.) have been modernized at a later stage, the year of the
modernization shall be regarded as the manufacturing year. For instance: A
machine manufactured in 1934 that has been modernized in the 1950’s with
plunger rear suspension and telescopic front fork shall be regarded as a
machine from the 1950’s. The year of manufacture for a newly constructed copy
is to be regarded as the same year as the original machine.
