SERIES:
8 event points series run at
Rockingham Dragway and Maryland
International Raceway.
DESIGNATION: All entrants
must display, on both sides of the
bike, the class designation OPS,
preceded by rider number.
CLASS DESCRIPTION: Outlaw
Pro Street was conceived to
provide a competitive venue for
the fastest production-based no
wheelie bar bikes in the country.
Motorcycles in this class will
have been originally born as
showroom factory super bikes, but
have since been transformed into
all-out dedicated quarter mile
racing machines. The bikes factory
heritage should still be readily
visible, but no equipment
necessary for street operation is
required.
FORMAT: Races will be a
qualified 16-bike field.
Qualifying and eliminations will
be heads-up, run on a .400 pro
tree, with all pro class rules in
effect. If any bike is unable to
make the first round call,
alternates will be allowed to take
their place in the ladder, with
the first alternate to be the
quickest non-qualified legal
entrant. Alternates must have
completed at least one legal
qualifying attempt to be eligible
for alternate status.
FRAME:
Factory OEM frames must be used,
no aftermarket frames will be
allowed. Any brackets, tabs,
braces, mounts, gussets, seat
rails, etc. may be moved,
modified, replaced, or removed.
Steering neck angle may altered,
but must remain in original
location. Rake may not exceed 40
degrees. Neck may be replaced with
aftermarket neck. Subframe and/or
seat rails may be modified, but
seat must remain in the original
forward/aft location. Seat may be
lowered, but must have a minimum
height from the ground of 20
inches. This measurement will be
made with rider on bike and
padding compressed. No
modifications to main frame or
engine cradle will be allowed,
except as noted otherwise. On
factory perimeter-style frames
(including, but not limited to,
Suzuki GS, oil-cooled GSXR,
water-cooled GSXR, and Kawasaki KZ),
engine cradle tubes must remain
intact and unmodified; i.e. no
cutting, sectioning, splicing,
relocating etc. allowed. "Engine
cradle tubes" will be defined as
the tubes, which connect to the
steering neck, pass down the front
and under the motor, back up
behind the motor, and across the
top of the motor, reconnecting to
the steering neck and/or front
downtubes. On steel frames, main
backbone tube may be replaced with
a tube of larger diameter to
facilitate the installation of a
backbone fuel cell. On factory
spar-style frames (including most
modern sportbikes), main frame
spars must remain intact and
unmodified. "Main frame spars" are
defined as the large formed tubes,
which connect the steering neck,
engine mounts and swingarm pivot.
FRONT SUSPENSION:
Rigid front forks not allowed, a
minimum of 1” of front suspension
travel recommended. Steering
dampers recommended, and may be
required in the future.
REAR SUSPENSION:
Rear suspension optional.
GROUND CLEARANCE:
All components, including
bodywork, must have a minimum of 2
inches of static ground clearance.
Static ground clearance
measurements will be taken with
the rider seated on bike, hands on
handlebars, and feet forward with
heels only contacting the ground.
(Dynamic Ground Clearance: Ground
clearance during the run, or
dynamic ground clearance,
constantly changes due to tire
flex/growth, suspension movement,
chassis and swingarm flex, etc.
Because of the many variables
involved in actual ground
clearance during the run, there is
no reasonable method to measure
this value. Static ground
clearance, or ground clearance
with the bike sitting stationary,
is the only defined measure for
ground clearance. However, in the
interest of safety, any entrant
observed by the MIROCK technical
staff to have an unsafe amount of
dynamic ground clearance may be
required to alter their bike or
setup, even if they pass the
static ground clearance
measurement. This may be done at
any time during the event, and the
manner or methods of these
alterations will be determined on
a case-by-case basis).
SWINGARMS:
Swingarm-style rear suspension
required, no fully welded
tail-sections allowed. Any stock,
modified stock, or aftermarket
swingarms will be allowed.
Swingarm pivot location may be
moved, but must be within 2 inches
of original factory location.
Pivot axle diameter may be
enlarged. Bikes with working rear
suspension are allowed any type
suspension system, as long as it
utilizes a conventional-style
single front pivot. Bikes with
solid rear suspension must utilize
a bolt-on swingarm, with a
conventional style front pivot
bolt or bolts. Swingarm may not be
welded to the frame in any manner.
Swingarm may be attached to the
frame and/or subframe, utilizing
struts or braces, at a maximum of
6 points, not including the pivot
bolt(s). Chain guards are required
on all entries.
BRAKES:
Front and rear hydraulic brakes
are required. All brake systems
must be properly adjusted, and
must be fully functional.
BODY:
Gas tanks are required on all
bikes, and must resemble a
production tank in both location
and style. Tanks may be lowered,
lengthened, or otherwise altered,
but must generally maintain
original overall appearance, size,
and shape. Tanks need not be
functional. In addition to gas
tanks, rear bodywork/seat sections
are required. Rear bodywork may be
extended, but must maintain
general overall appearance and
shape of original bodywork. Seat
may be lowered, but must remain in
the same general location as the
factory seat (bikes with plain
bearing motors, may re-locate seat
anywhere on motorcycle). One-piece
bodies are allowed. Front fairings
and/or headlight buckets are not
required, but are legal. If used,
front bodywork should closely
resemble factory bodywork in size
and shape. No aerodynamic devices,
such as wings, fairings, or air
dams, may be used, unless
originally equipped. Engine air
inlets or scoops may be added.
FRONT FENDER: Front fenders
are required for all entrants.
Fender does not have to be an
exact duplicate of original
fender, but it must be of a style
that suitably matches the bike and
bodywork.
ENGINES:
Any engine originally used in a
production motorcycle may be used.
Approved aftermarket engine cases
are allowed.
CLUTCH:
Slider clutches are permitted.
"Slider Clutches" are defined as
any clutch system, which utilizes
only engine-driven centrifugal
force to engage the clutch. Any
style mechanical clutch permitted.
TRANSMISSIONS:
Automatic transmissions are
permitted.
ENGINE SWAPS:
Limited modifications to the stock
frame will be allowed for the sole
purpose of interchanging engine
types. These modifications will be
limited to the absolute minimum
required for the swap.
Modifications intended for the
purpose of improved weight
distribution are strictly
disallowed. Race tech has final
ruling on this issue, and
pre-approval is required.
STARTING SYSTEMS:
On-board starting systems
required. No external starters,
batteries, or boosters allowed. No
push-starts.
ELECTRICAL:
Any ignition or electrical systems
allowed, including nitrous
progressives, boost controllers
for supercharged bikes, fuel
injection controllers, and data
acquisition systems.
DATA ACQUISITION:
No front wheel speed sensors or
third wheel speed sensors allowed.
Rear-wheel speed sensors, both
directly measured and those
derived from countershaft or other
shaft speed sensors, may be used
for information gathering only.
Rear-wheel speed data may not be
used to active or deactivate any
electrical or mechanical devices.
No devices, which measure
performance, on-track location,
the Christmas tree, or any other
part of the track or timing
system, are allowed. No traction
control or wheelie control systems
allowed. No type of electrical or
measuring devices may be mounted
to or activated by any part of the
front or rear suspension.
KILL SWITCHES:
Tether kill switches required on
all entrants. Kill switch, when
activated, must disable ignition,
fuel pump(s) and nitrous system
solenoids.
NITROUS OXIDE:
Entrants running nitrous oxide may
use any type nitrous oxide system,
but cannot be combined with any
other type of power adder.
SUPERCHARGERS:
Entrants running a supercharger
may use engine-driven
superchargers. Supercharged
entrants are allowed one type of
inlet air-cooling, either water
injection or intercooling.
Intercooling is limited to forced
ambient air-to-air heat
exchangers. The use of water or
other liquids, ice, dry ice, or
cryogenics as a form of
intercooling is not allowed.
TURBOCHARGERS:
Turbochargers are prohibited.
TIRES:
Motorcycle tires only, no car
tires on rear. DOT or racing
slicks allowed, maximum width 7
inches.
WHEELBASE:
Maximum wheelbase measurements are
absolute, no over tolerance
allowed. Wheelbase will be
measured with rider sitting on
bike.
GENERAL SAFETY:
All riders must have full leathers
(zipped together leathers are
recommended and may be mandatory
in future). All riders must have a
SNELL 95 or higher full-face
helmet with shield, leathers
gloves, and shoes above the ankle.
All motorcycles and riders must
pass IHRA safety inspection.
Ballistic blankets are recommended
but are not required.
NITROUS BOTTLES:
Bottles must be fully enclosed
within the bodywork and/or frame
rails. Bottles may not be
externally mounted to foot pegs,
swingarms, etc.
BALLAST:
All ballast must be securely
mounted. Ballast is defined as any
component attached to any part of
the motorcycle, whose sole purpose
is to add weight to the
motorcycle. Any component,
regardless of weight, which serves
a structural or mechanical
function, is not considered to be
ballast. i.e.; As a general
reference, if the component in
question can be removed without
affecting any mechanical functions
of the motorcycle, or decreasing
structural integrity of the
motorcycle, it is considered
ballast. If, however, removing a
given component would cause a
failure within some mechanical
system (such as the wheel rolling
or the brakes working) that
component is considered to not be
ballast. MIROCK does, however,
reserve the right to deem any
non-ballast component to be
illegal, if its excessive weight
creates a safety hazard. Front
suspension components, including
axles, wheels and brakes, may not
be filled with any non-structural
material, including lead. Tires
may not be filled with any liquid
or solid materials. No ballast may
be mounted on the front brakes,
front wheel, or the front
suspension below the bottom triple
clamp. No parts of the front
suspension, mounted below the
bottom triple clamp,
including brakes, fender and
mounts, or wheel/brake rotor
assembly, may be remanufactured
with the intent of adding weight
to the front suspension. OEM or
standard-available aftermarket
parts are preferred. Custom-made
parts should be of a similar size,
material, and weight as the OEM
parts they are replacing. MIROCK
tech has the final decision on
this matter.
BIKE & RIDER MINIMUM WEIGHT:
Minimum weights include the rider
and the motorcycle (see chart
below).
RIDER WEIGHT:
No minimum rider weight for the
class.
RULE REVISIONS:
In order to maintain a level
playing field, MIROCK will monitor
the performance numbers of the
numerous combinations of rider
weights and power adders found in
this class. From time to time, it
may be necessary to adjust the
wheelbase, ground clearance and
weights to help promote class
parity. Racers should take this
into consideration when
constructing their bikes, and
should allow room in their
swingarms, bodywork, fenders, etc.
for changes in wheelbase and
ground clearance. Any rule
revisions deemed necessary by
MIROCK would be officially posted
a minimum of 14 days prior to the
event in which they become
effective. The official rules
effective for any event will be
those posted on the MIROCK website
on the day that event begins. Any
rule revision deemed necessary for
the reasons of safety may be made
at any time, even after the start
of an event, and may be made
effective immediately. |
