SUPERSTOCK 600 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 AUTHORIZED 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 (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.
For 2016: 2013-2015 Kawasaki ZX-6R (636) is accepted as homologated for
2016 MotoAmerica competition.
The appearance from the 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.
2.7.1
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.
2.7.2
Engine configurations and displacement capacities
The following engine configurations comprise the Superstock class:
Over 401cc up to 600cc
4-stroke
4 cylinders
Over 401cc up to 675cc
4-stroke
3 cylinders
The displacement capacity, bore and stroke (new), must remain at the
homologated size. All machines must be normally aspirated.
2.7.3
Balancing various motorcycle concepts
1
In order to equalize the performance of motorcycles used in the Superstock 600
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 MotoAmerica Permanent
Bureau based on decisions made by the Superbike Commission at any time
deemed necessary to ensure fair competition.
2.7.4
Minimum weight
Over 401cc up to 600cc
Over 401cc up to 675cc
4 cylinders
3 cylinders
164kg (360.8lbs)
164kg (360.8lbs)
For 2016: 2013-2016 Kawasaki ZX-6R (636) minimum weight- 166 kg (365.2 lbs)
At any time of the event, the weight of the whole motorcycle (including the tank
and its contents) must not be lower 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 MotoAmerica Technical Director at the
preliminary checks.
2.7.5
Numbers and Number Plates
The background colors and figures (numbers) for Superstock 600 are red
(pantone 186c) background with yellow (pantone yellow) numbers:

Main 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 MotoAmerica Technical Director.
The pre-assembled spare frame must be presented to the MotoAmerica
Technical Director to receive the permission to rebuild the motorcycle. The preassembly 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 MotoAmerica Technical Director.
The motorcycle, once rebuilt, prior to use must be inspected by the technical
stewards for safety checks and a new seal will be placed on the motorcycle
frame.
EXPLANATION OF THE PROCEDURES
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.
The frame of this motorcycle will be officially sealed by the MotoAmerica
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
MotoAmerica 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.
10
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.
When a team decides that a crashed or damaged motorcycle requires a change
of frame, it must inform the MotoAmerica 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 MotoAmerica 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 MotoAmerica 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 Sporting Regulations

c. Wind screen may be replaced with an aftermarket product. The height of
the windscreen is free and must be 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 – no double
bubble or wide types. 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

altered or replaced. Carbon fiber composites and other exotic materials
are forbidden. Particle grills or “wire-meshes” originally installed in the
openings for the air ducts may be removed.
g. The lower fairing must to be constructed to hold, in case of an engine
breakdown minimum 6 liters. The lower edge of all the openings in the
fairing must be positioned at least 70 mm above the bottom of the fairing.
16
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 centers, circle
centers 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 as declared by the Race Director.
k. Front mudguards may be replaced with a cosmetic duplicate of the original
parts and may be spaced upward for increased tire 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
towards the radiator but the appearance of the front, the rear and the
profile of the motorcycle must not be changed.
2.7.10.11
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 bodywork 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.
2.7.10.12
Rear Safety Light
All motorcycles must have a functioning red light mounted at the rear of the
machine, this light must be switched on any time the motorcycle is on the track or
being ridden in the pit-lane and the session is declared WET. All lights must
comply with the following:
a. Lighting direction must be parallel to the machine center line (motorcycle
running direction), and be clearly visible from the rear at least 15 degrees to
both left and right sides of the machine center line.
b. The rear light must be mounted near the end of the seat/rear bodywork
and approximately on the machine center line, in a position approved by the
Technical Director. In case of dispute over the mounting position or visibility,
the decision of the Technical Director will be final.
17
c. Power output/luminosity equivalent to approximately: 10 – 15 (incandescent),
0.6 – 1.8 W (LED).
d. The output must be continuous - no flashing safety light whilst on track,
flashing is allowed in the pit lane when pit limiter is active.
e. Safety light power supply may be separated from the motorcycle.
f. The Technical Director has the right to refuse any light system not
satisfying this safety purpose.
2.7.10.13
Fasteners
a. Standard fasteners may be replaced with fasteners of any material and
design but titanium fasteners cannot be used. The strength and design
must be equal to or exceed the strength of the standard fastener.
b. Fasteners may be drilled for safety wire, but intentional weight-reduction
modifications are not allowed.
c. Thread repairs may be made using inserts of different material such as
helicoils and timeserts.
d. Fairing / bodywork fasteners may be replaced with the quick disconnect
type.
e. Aluminum fasteners may only be used in non-structural locations.
2.7.11
