SUPERSPORT TECHNICAL REGULATIONS
The following rules are intended to give freedom to modify or replace some
parts in the interest of safety, research and development and improved
competition between various motorcycle concepts.
EVERYTHING THAT IS NOT AUTHORISED AND PRESCRIBED IN THIS RULE
IS STRICTLY FORBIDDEN
If a change to a part or system is not specifically allowed in any of the
following articles, then it is forbidden.
Supersport motorcycles require an FIM homologation (see Appendix
FIM Homologation procedure for Superstock, Supersport and Superbike
motorcycles). All motorcycles must comply in every respect with all the
requirements for road racing as specified in these Technical Regulations,
unless they are already equipped as such on the homologated model.
Once a motorcycle has obtained the homologation, it may be used for
racing in the corresponding class for a maximum period of 8 years, or until
such time that the homologated motorcycle is disqualified by new rules or
changes In the Technical specifications of the Corresponding class.
The appearance from the front, rear and the profile of Supersport motorcycles
must (except when otherwise stated) conform in principle to the homologated
shape (as originally produced by the manufacturer). The appearance of the
exhaust system is excluded from this rule.
2.5.1
Motorcycle specifications
All parts and systems not specifically mentioned in the following articles
must remain as originally produced by the manufacturer for the homologated
motorcycle.

2.5.2
Balancing various motorcycle concepts
In order to equalize the performance of motorcycles used in the Supersport
World Championship, A system of performance enhancements or restrictions
can be developed. (Such as minimum weight, air restrictor or REV Limit may
be applied according to their respective racing performances.) The decision
to apply a balancing system to a motorcycle will be taken by the Superbike
Commission at any time deemed necessary to ensure fair competition.
2.5.3
Engine configurations and displacement capacities
The following engine configurations comprise the Supersport class.
Over 400cc up to 600cc
Over 500cc up to 675cc
Over 600cc up to 750cc
4 stroke
4 stroke
4 stroke
4 cylinders
3 cylinders

The displacement capacity bore and stroke must remain at the homologated
size. Modifying the bore and stroke to reach class limits is not allowed.
Minimum weight
The minimum weight will be: 600cc
675cc
750cc
4 cylinders
3 cylinders

161 kg
161 kg
161 kg
At any time during the event, the weight of the whole motorcycle (including
the tank and its contents) must not be less than the minimum weight.
There is no tolerance on the minimum weight of the motorcycle.
During the final technical inspection at the end of the race, the selected
motorcycles will be weighed in the condition they finished the race, and
the established weight limit must be met in this condition. Nothing may be
added to the motorcycle. This includes all fluids.
During the practice and qualifying sessions, riders may be asked to submit
their motorcycle to a weight control. In all cases the rider must comply with
this request.
The use of ballast is allowed to stay over the minimum weight limit and
may be required due to the handicap system. The use of ballast and weight
handicap must be declared to the FIM Superbike Technical Director at the
preliminary checks.

Main frame and pre-assembled spare frame
During the entire duration of the event, each rider can only use one (1)
complete motorcycle, as presented for Technical Control, with the frame
clearly identified with a seal. In case the frame needs to be replaced, the
rider or the team can request the use of a spare frame to the FIM Superbike
Technical Director.
108
update 22 January 2015
Road Racing FIM SBK and SS World Championships and FIM SST Cup Regulations
The pre-assembled spare frame must be presented to the FIM Superbike
Technical Director to receive the permission to rebuild the motorcycle. The
pre-assembly of the frame shall be strictly limited to:
•
•
•
•
•
•
Main frame
Bearings (steering pipe, swing arm , etc)
Swing arm
Rear suspension linkage and shock absorber
Upper and lower triple clamps
Wiring harness
The spare frame will not be allowed in the pit box before the rider or the
team has received authorization from the FIM Superbike Technical Director.
The motorcycle, once rebuilt, must be inspected before its use by the
technical stewards for safety checks and a new seal will be placed on the
motorcycle frame.
EXPLANATION OF THE PROCEDURES
The frame of this motorcycle will be officially sealed by the FIM Superbike
Technical Director or by his appointed staff. The seal will bear a serial
number, which will be recorded. Any attempt made to remove the seal will
damage it irreparably.
At any time during the event the technical stewards, under the direction of
the FIM Superbike Technical Director, may check the seal and verify that it
conforms to the motorcycle and rider it was assigned to. For cross reference,
every frame must have a unique number punched on it, preferably on the
steering-head.
If the motorcycle is damaged in a crash or in any other incident, it is allowed
to use the pre-assembled spare frame to rebuild the motorcycle.
The spare frame may be pre-assembled with the following items: main frame
assembly, swing-arm, rear suspension linkage, shock-absorber, steering head
bearings, upper and lower triple clamps and wiring harness.

update 22 January 2015
SS
Only one (1) complete motorcycle may be presented for the preliminary
technical checks and it will be the only motorcycle allowed on the track and
in the pit box during the practices, qualifying, warm up and race.
Road Racing FIM SBK and SS World Championships and FIM SST Cup Regulations
When a team decides that a crashed or damaged motorcycle requires a
change of frame, it must inform the FIM Superbike Technical Director. Only
at this point may the pre-assembled spare frame be brought into the pit
box.
Parts may be transferred from the damaged motorcycle for the assembly of
the replacement motorcycle.
Once the assembly of the replacement motorcycle is completed, it will then
undergo technical and safety checks and it will be officially sealed. The seal
on the damaged motorcycle will be destroyed by the technical staff and the
chassis of this motorcycle must not be used for the remainder of the event.
The new serial number will be recorded by the FIM Superbike Technical
Director.
The replacement motorcycle may be used on the track only after the end of
the practice and qualifying sessions or race in which the damage occurred.
The damaged motorcycle must be removed from the pit box as soon as
possible and put in storage outside the pit box.
After the pre-assembled spare part frame has been used, should it become
necessary to replace the frame again because of a further crash or damage,
the assembly work must be done using a bare frame with no components
attached. The FIM Superbike Technical Director must inspect the bare frame
and give his approval before work can start.
Any actions contrary to these procedures will result in a penalty as described
in the Technical Regulations

fairing must be positioned at least 50 mm above the bottom of the
fairing.
e)The lower fairing must incorporate one hole of 25 mm in the bottom of
the front lower area. This hole must remain closed in dry conditions and
must be only opened in wet race conditions, as declared by the Race
Director.
f)
Minimal changes are allowed in the fairing to allow clearance for
protective engine covers.
