1 SUPERBIKE TECHNICAL SPECIFICATIONS
The following rules are intended to permit limited changes to the homologated
motorcycle in the interests of safety 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 Superbike motorcycles require an FIM homologation. All
motorcycles must comply in every respect with all the requirements for Road Racing
as specified in these Regulations, unless they are already equipped as such on the
homologated model.
The appearance from both front, rear and the profile of Superbike motorcycles must
(except when otherwise stated) conform to the homologated shape (as originally
produced by the manufacturer). The appearance of the exhaust system is excluded
from this rule.
1.1 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
1.2 Displacement capacities
The following engine configurations comprise the Superbike class:
Over 750 cc up to 1000 cc 4-stroke 3 and 4 cylinders
Over 850 cc up to 1200 cc 4-stroke 2 cylinders
The displacement capacity, bore and stroke (new), must remain at the homologated
size.
1.3 Minimum Weights
The minimum weight for each model is calculated by FIM by determining the “dry
weight” of the homologated motorcycle.
The ‘dry’ weight of a homologated motorcycle is defined as the total weight of the
empty motorcycle as produced by the manufacturer (after removal of fuel, vehicle
number plate, tools and main stand and side stand when fitted but with oil and
radiator liquid at prescribed level). To confirm the ‘dry’ weight a minimum of three
(3) motorcycles are weighed and compared. The result will be rounded off to the
nearest digit.
In any case the minimum weight cannot be lower than 170 Kg
At any time of the event, the weight of the whole machine (including the tank and its
contents) must not be lower than the minimum weight. There is no tolerance on this
minimum weight.
021.11.8 SUPERBIKE LUOKKASÄÄNTÖ 2018 1.0
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.
1.4 Kilpailunumerot
Moottoripyörässä tulee olla yksi kilpailunumero edessä ja yksi molemmilla sivuilla.
Numeroiden tulee olla selvästi luettavissa ja niiden tulee erottua katteiden väristä. Lisäksi
numeroiden tulee olla urheilusäännöstön kohdan 030 ja piirroksen ”O” mukaiset.
1.5 Polttoaine
Moottoripyörässä on käytettävä SML:n urheilusäännöstön kohdan 032.1 mukaista
polttoainetta. Polttoaineeseen ei saa lisätä lisäaineita

parts may be used. Electronic suspension may be used if such suspension is already
present on the production model of the homologated motorcycle, and it must
remain completely standard (all mechanical and electronic parts must remain as
homologated) with the exception of shims and springs. The original suspension
system must work safely in the event of an electronic failure. The electronic front
suspension may be replaced with a mechanical system from a similar homologated
model from the same manufacturer.

as homologated) with the exception of shims and springs). The original suspension
system must work properly safely in the event of an electronic failure. The electronic
shock absorber can be replaced with a mechanical one.

metallic shims to the callipers, between the pads and the callipers, and/or to replace
light alloy pistons with steel pistons made by the same manufacturer of the calliper.
d. The rear brake calliper bracket may be mounted fixed on the swingarm, but the
bracket must maintain the same mounting (fixing) points for the calliper as used on
the homologated motorcycle.
e. The swing-arm may be modified for this reason to aid the location of the rear
brake calliper bracket, by welding, drilling or by using a helicoil.

material. These covers must fit the shape of the fuel tank.
1.9.10 Fairing / Body work
a. Fairing and bodywork may be replaced with exact cosmetic duplicates of the
original parts, but must appear to be as originally produced by the manufacturer for
the homologated motorcycle, with slight differences due to the racing use (different
