02.6. SuperStock 1000 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
SuperStock 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 SuperStock 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.
02.6.1 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
02.6.2 Displacement capacities
The following engine configurations comprise the SuperStock 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.
All machines must be normally aspirated.
02.6.3 Balancing various motorcycle concepts
In order to equalise the performance of motorcycles with different engine configurations,
changes in the minimum weight may be applied according to their respective racing
performances. The decision about applying a handicap system to a respective class is
taken by the FMSCT/TSB Commission at any time.
02.6.4 MinimumWeights
The minimum weight starting the season will be:
1000 cc.
3 & 4 Cylinders
174 Kg.
1200 cc.
2 Cylinders
174 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.

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 FMSCT/TSB Technical Director at the preliminary checks.
02.6.5 Number Plate Colours
The background colours and figures (numbers) for SuperStock are red background with
white numbers:
The sizes for all the front numbers are:

a. Fuel tank must remain as originally produced by the manufacturer for the
homologated motorcycle.
b. All fuel tanks must be completely filled with fire retardant material (open- celled
mesh, i.e. Explosafe).
c. Fuel tanks with tank breather pipes must be fitted with non-return valves that
discharge into a catch tank with a minimum volume of 250cc made of a suitable
material.
d. Fuel cap must be changed for a “screw type” cap to prevent accidental opening at
any time. Fuel cap when closed must be leak proof.
e. The sides of the fuel tank may be protected with a cover made of a composite
material. These covers must fit the shape of the fuel tank.
02.6.10.10 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
pieces mix, fixing points, fairing bottom, etc). The material may be changed. The
use of carbon fibre or carbon composite materials is not allowed. Specific
reinforcements in Kevlar® or carbon are allowed locally around holes and stressed
areas.
b. Overall size and dimensions must be the same as the original part, with a tolerance
of +-10mm, respecting the design and features of the homologated fairing as far as
possible. The overall width of the frontal area may be +10mm maximum. The
decision of the FMSCT/TSB Technical Director is final.
c. Wind screen may be replaced with an aftermarket product. The height of the
windscreen is free, within a tolerance of +/- 15 mm referred to 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 25mm to allow clearance for the rider. The edge of the screen must
have no sharp edges
d. Motorcycles that are 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 point (g). This device cannot exceed above a line drawn horizontally
from wheel axle to wheel axle and must follow the specifications described at point
(g).
e. The original combination instrument/fairing brackets may be replaced, but the use
of titanium and carbon (or similar composite materials) is forbidden. All other fairing
brackets may be altered or replaced.
f.
The original air ducts running between the fairing and the air box may be altered or
replaced. Carbon fibre composites and other exotic materials are forbidden. Particle
grills or “wire-meshes” originally installed in the openings for the air ducts may be
taken away.

g. The lower fairing must to 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.
h. The upper edge of the rear transverse wall of the lower fairing must be at least 70
mm above the bottom. The angle between this wall and the floor must be ≤ 90°.
i.
Original openings for cooling in the lateral fairing/bodywork sections may be
partially closed only to accommodate sponsors' logos/lettering. Such modification
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%.
j.
The lower fairing must incorporate a single opening of Ø 25 mm diameter in the
front lower area. This hole must remain sealed in dry conditions and must be only
opened in wet race conditions.
k. Front mudguards may be replaced with a cosmetic duplicate of the original parts
and may be spaced upward for increased tyre clearance.
l.
Rear mudguard fixed on the swing arm may be modified, changed or removed
m. Motorcycles may be equipped with inner ducts to improve the air stream
n. towards the radiator but the appearance of the front, the rear and the profile of the
motorcycle must not be changed.
02.6.10.11 Seat
a. Seat, seat base and associated bodywork may be replaced with parts of similar
appearance as originally produced by the manufacturer for the homologated
motorcycle. The appearance from front, rear and profile must conform to the
homologated shape
b. The top portion of the rear body work around the seat may be modified to a solo
seat.
c. The homologated seat locking system (with plates, pins, rubber pads etc.) may be
removed.
02.6.10.12 Rear Safety Light
All motorcycles must have a functioning red light mounted at the rear of the machine, to be
used in rain or low visibility conditions. All lights must comply with the following:
a. Lighting direction must be parallel to the machine centre line (motorcycle running
direction), and be clearly visible from the rear at least 15 degrees to both left and
right sides of the machine centre line.
b. The rear light must be mounted near the end of the seat/rear bodywork and
approximately on the machine centre line, in a position approved by the FMSCT/
TSB Technical Director. In case of dispute over the mounting position or visibility,
the decision of the FMSCT/TSB Technical Director will be final.
