modifications are allowed for safety reasons.
All motorcycles must comply in every respect with all the requirements for Road Racing as specified
in FIM Road Racing Technical Rules.
All parts of a motorcycle must consist of that year of production as the motorcycle is homologated. The
appearance from both front, rear and the profile of motorcycles must (except when otherwise stated)
conform to the homologated shape (as originally produced by the manufacturer).

condition they were at the end of the race.
At any time of the event, the weight of the whole motorcycle (including the tank) must not be
less than the minimum weight.
There is no tolerance on the minimum weight.
During the final inspection at the end of the race, the selected motorcycles will be weighted in the
condition they finished the race, and the established weight limit must be met in this condition.

Rules are intended to limit changes to the homologated motorcycle in the interests of safety.
EVERYTHING THAT IS NOT AUTHORISED AND PRESCRIBED IN THIS RULE IS STRICTLY FORBIDDEN
As the name Stocksport implies limited modifications are allowed to the Motorcycles. Most
modifications are onlyallowed for safety reasons.
Stocksport motorcycles require a FIM homologation (see Art. FIM 2.9 and AARR 0.6). All motorcycles
must comply in every respect with all the requirements for Road Racing as specified in these
Regulations, unless it is equipped as such on the homologated motorcycle.
The appearance from both front, rear and the profile of Superstock 600 / 1000 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.
5.1 Discipline Specifications Superstock 600 / 1000
Superstock 600
4 cylinders over 401 cc up to 600 cc 4stroke 3 cylinders over 401 cc up to 675 cc

The displacement capacities must remain at the homologated size. Modifying the bore and stroke to
reach class
limits is not allowed. All engines must be normally aspirated.
5.2 Minimum Weights
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 when fitted). To confirm the dry weight a minimum of three (3) motorcycles are weighed and
compared. The result is rounded off to the nearest digit.
In the final inspection at the end of the race, the checked s will be weighed in the condition they
were at the end of the race.
At any time of the event, the weight of the whole motorcycle (including the tank) must not be
less than the minimum weight.
There is no tolerance on the minimum weight.
During the final inspection at the end of the race, the selected motorcycles will be weighted in the
16
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.
Superstock 600: minimum weight = dry weight minus 12 kg.
Superstock 1000: minimum weight = dry weight minus 12 kg. In any case the minimum weight of
SStk 1000 motorcycles cannot be lower than 165 kg!
5.3 Starting Number

23
d. Non-folding footrests must have an end (plug) which is permanently fixed, made of plastic, Teflon
or an equivalent type material (Alloy) (minimum radius 8mm). The plug surface must be designed to
reach the widest possible area in order to decrease the risk of injuries to the rider in the case of an

c. The homologated seat locking system (with plates, pins, rubber pads, etc.) can be removed.
5.8.10 Fairing / Body Work
a. Fairing, front mudguards and body work may be replaced with cosmetic duplicates of the
original parts, which must appear to be as originally produced by the manufacturer for the
homologated motorcycle, or with slight differences due to the racing use permitted (different
pieces mix, attachment points, fairing bottom, etc.).

allowed with the following exceptions: Local specific reinforcements made of Kevlar or Kevlar-carbon
is allowed around the holes and other stressed points.
c. Overall size and dimensions must be the same as the original parts, with a tolerance of +/- 10 mm,
respecting the design and features of the homologated fairing as far as possible. The overall

with a tolerance of + 40 mm (FIM +/- 15 mm) measured on the vertical distance from to the upper
fork bridge. The screen must conform to the same profile from the front as the original. From a top
view the length of the windscreen may be shortened by 25 mm to allow clearance for the rider.
The screen must have no sharp edges.
e. Motorcycles that were not originally equipped with streamlining are not allowed to add
streamlining in any form, with the exception of a lower fairing device, as described in (g and h). This
device cannot exceed above a line drawn horizontally from axle to axle and must follow the
specifications described at point g).
f. The original combination of instrument/fairing brackets may be replaced, regardless of
the material. All other fairing brackets may be altered or replaced.
g. The original air ducts running between the fairing and the air box may be altered or replaced.
Particle grills or “wire-meshes” originally installed in the openings for the air ducts may be taken
away.
h. The lower fairing must be constructed to hold, in case of an engine breakdown minimum 6 litres.
The lower edge of all the openings in the fairing must be positioned at least 70 mm above the
bottom of the fairing.
i. The lowest point of the rear transverse wall of the lower fairing must be at least 70 mm above
thebottom. The angle between this wall and the floor must be </=90°.
j. Original openings for cooling in the lateral fairing/bodywork sections may be partially closed
only to accommodate sponsors’ logos/lettering. Such modifications shall be made using wire
mesh or perforated plate. The material is free but the distance between all opening centres, circle
centres and their diameters must be constant. Holes or perforations must have an open area
ratio > 60 %.
k. The lower fairing must incorporate at least a hole of 25 mm (minimum) diameter in the
bottom front lower area. This hole must remain closed in dry conditions and must be opened
only in wet race conditions as declared by the Clerk of the Course.
l. Front mudguard may be replaced with a cosmetic duplicate of the original parts and may be
spaced upward for increased tyre clearance.
m. Rear mudguard fixed on the swing arm can be modified, changed or removed.
n. Motorcycles can be equipped with inner ducts to improve the air stream towards the radiator but
the appearance of front, rear and the profile must not be changed.

a. Standard bolts and fasteners may be replaced with fasteners of any material and design, but
titanium bolts and fasteners cannot be used. The strength and design must be equal to or exceed

composite material if these parts do not replace original parts mounted on the homologated model.
g. Any type of spark plug.
h. Any tyre inner tube (if fitted) or inflation valves may be used, but metal valve stems with metal
stem caps are highly recommended.
