Nitrous oxide may not be used in conjunction with any turbocharged entrants, with the exception of draw through carbureted turbo or production-1000cc entries. Air or electric shifters permitted. All engines must be self-starting and utilize OEM-style starting systems. No push or roller starts.
NITROUS OXIDE: Entrants allowed to run nitrous oxide may use any style nitrous system with any number of solenoids or nozzles.
TURBOCHARGERS: Entrants are limited to one turbo with a maximum turbo inlet opening of 62.5mm. Shakedown Tech defines maximum turbo size as the maximum allowable diameter of the inlet housing at the point where the leading edge of the compressor wheel meets the inlet housing. All air entering the turbo must pass through this opening. No stepped inducer wheels permitted, the contour from the inducer to the exducer must be continuous without steps. The leading edge of inducer wheel may not exceed 62.5mm, and must it inside the 62.5mm area of the inlet housing. The use of restrictor plates or stepped inlet housings in an effort to limit compressors with inducers larger than 62.5mm is not acceptable.
INLET COOLING: Any type of inter-cooling permissible. Turbocharged entrants that are prohibited from the use of nitrous may not use nitrous as cryogenic cooling source. Entrants utilizing water injection must have the water tank mounted in a manner to allow tech to easily inspect its contents. Absolutely no substance other than water is permitted to be in the tank.
TURBO & INTERCOOLER MOUNTING: Any part of the turbo or induction system may be mounted within the original bodywork/frame envelope in any available location. Components mounted outside of the bodywork are limited to an area no higher than 24 inches above the ground, 18 inches to either side of the bike centerline, and no more than 3 inches forward of the front axle.
SUPERCHARGERS: Any style engine-driven supercharger is allowed.
CLUTCH: All clutch systems must be approved for use in this class. Each interested manufacturer or team must submit sample parts for approval. No pneumatic, electric, or hydraulic clutch engagement or activation systems are permitted.
TURBOCHARGED & SUPERCHARGED: Slider clutches prohibited. Clutch engagement and disengagement must be controlled by conventional cable or hydraulic-actuated clutch lever. Minimum 80 lbs of static spring pressure at installed height required. Engine RPM must decrease with the release of clutch lever at 1200 RPM. If entrant will not idle at 1200RPM, the tech director will determine a reasonable idle value.
NITROUS INJECTED: Any approved clutch system permitted.
TRANSMISSIONS: All entrants must utilize an OEM-style shift drum and transmission.
TURBOCHARGED & SUPERCHARGED: Automatic transmissions prohibited. No transmission that could allow override-style shifting is permitted. No components may be used that are designed to allow the transmission to be simultaneously engaged in more than one gear. This includes, but not exclusive to, windowed shift drums, split forks, split gears, split fork slider rings, gear or fork detent springs, etc.
NITROUS INJECTED: Automatic transmissions permitted.
TRIPLE CLAMPS: The steering stem offset on top and bottom triple clamps must be equal. Front axle offset may not be less than 1/2-inches. The use of triple clamps, steering stems, stem bearings, offset bearing races, or any other components designed to increase or decrease the rake is prohibited. Axle must be in the center of the forks. Triple clamps can be made of a material other than aluminum only after approval of concept. Bottom of lower triple tree cannot be higher (must be flush or lower) than webbing of lower steering neck.
FRAME: Stock OEM frames required. No modifications to any portion of frame permitted, unless specifically noted.
ALLOWABLE MODIFICATIONS:
ALL BIKES: Frames may be polished, chromed, painted, powder coated, or otherwise cosmetically altered, as long as such modifications do not remove substantial material or weaken the frame. No braces, gussets, or crossbars may be removed, unless specifically listed. Additional braces, gussets, or crossbars may be added, as long as they do not weaken the frame in any manner.
Small accessory brackets, tabs, mounts, etc., using fasteners no larger than 5/16” (8mm) may be removed, relocated, or modified. New accessory mounts may be installed, and new mounting holes may be drilled into the frame, as long as the hole size does not exceed 5/16” (8mm). An excessive number of mounting holes will be considered lightening of the frame, and is not permitted. Exhaust mounting brackets, center-stand, and side-stand brackets, regardless of fastener size, may be removed as long as doing so does not weaken the frame.
On turbocharged entrants, steering heads must remain stock, with the exception of the lower steering stem bearing race area. The bottom of the steering head may be re-machined or removed and replaced in order to increase the clearance between the front tire and the bottom triple clamp, a technique commonly referred to as “short necking”. If short-necking has been performed, the new bearing race cup must use the factory bearing race, and may not be located more than 1.00 inches above the original bottom webbing of the steering neck. The replaced or modified bearing race cup must be located along the same axis as the original location, i.e., the rake of the steering stem may not be altered during this modification. No other material beyond that reasonably necessary to perform the short-neck modification may be removed from the steering neck casting, with the exception of removal or modification of the steering stops and/or the headlight/fairing mount.
For non-turbocharged entrants, frames may be altered in order to increase the rake. No de-raking of frames will be permitted. Location of bottom triple clamp must be in the same general location as the legal modifications permitted for turbocharged entrants.
Seat rails/sub-frames may be modified or relocated. Mounting tabs or brackets for these items may be modified or relocated as well.
Rear suspension mounts including shock mount and rising rate linkage mounts may be relocated. However, due to the extreme loads and potential safety issues, modifications to these components will be heavily scrutinized.
On turbocharged entrants, swingarm pivot mounts may not be modified. Swingarm pivot centerline cannot be moved in any manner, including offset bushings, plates, etc. Proper design, welding, and bracing are crucial in these areas. Non-turbocharged entrants are permitted to relocate the swingarm pivot axle up to 2” from its factory location. Engine mounting tabs and brackets may not be modified. Bolt-on engine mounts may be replaced, but must maintain the same mounting dimensions as the factory mounts. Engine relocation in any manner is not permitted.
HONDA BLACKBIRD: The round tubular cross-brace, located directly behind the steering stem, may be removed. Upper rear sub-frame mount may be removed. It may be cut off flush with the top of the factory frame spar, but no farther.
KAWASAKI ZX-12, ZX-14: Airbox inlets may be welded shut, or modified for better sealing with turbo dump pipe, as long as these openings are not enlarged. Access panels for throttle body/airbox connectors may be modified, as well as the mounting area for the connectors. These modifications may not weaken the frame. Opening for turbo pop-off valve may be cut in airbox area of frame as needed, as well as mounts or bungs for air sensors.
SUZUKI GSXR (EARLY MODELS): 1986-1987 750 and 1986-1988 1100 models may remove the square tubular cross-brace located generally above the carburetors.
Late model liquid cooled models, factory equipped with engine mounts connecting between the cylinder head and the upper frame spar, are not required to use these mounts. The mounting tabs for these mounts may be removed from the frame.
SUZUKI HAYABUSA: The round tubular cross-brace, located directly behind the steering stem, may be removed. Upper rear sub frame mount may be removed. It may be cut off flush with the top of the factory frame spar, but no farther.
SUZUKI GS & KAWASAKI KZ/Z1: Frames may be modified for a backbone fuel cell. Backbone cell may not be used to hold any fuel or other liquids.

This can include a laptop or PC, software, passwords, download cables, etc. It is also necessary that the competitor, or someone within the competitor’s team, is knowledgeable in the system being used, and is capable of assisting tech officials in navigating through any and all portions of the software. Shakedown tech may also impound any component of an ECU or data recording system for further examination either onsite or off site. Refusal to submit to any examination or failure to supply the required components for examination is grounds for disqualification and/or suspension. ECUs may not detect and may not be activated by radio transmitters, infrared, laser or sonic devices, or any track position devices or beacons. Also, they may not wirelessly (ie radio, infrared, sonic. etc) transmit or receive information during the run to or from any source.
DATA ACQUISITION: Any electrical or mechanical device that may be used to activate, adjust, or tune any engine function based upon ride height, track position, front wheel speed, or front suspension conditions, is prohibited. Any sensors, including infrared or ultrasonic, that measure the track Christmas tree or timing system, the track surface, or any structure of the track facilities are prohibited. Any non contact sensor (sonic, infrared, radar, laser, etc) designed to detect or measure distance, position, or location is prohibited. The use of GPS, locator or position beacons, and locator or position transmitters is prohibited. Third wheel sensors, which is the use of any wheel or rolling device other than the normal front steering or rear drive wheel/tire to measure speed, distance, or track position, is prohibited. Any sensors measuring front wheel/tire speed, position, temperature, or pressure are prohibited. Any sensor measuring any function of the suspension including travel, distance, position, or external or internal fork or shock conditions are prohibited. Any mechanical, infrared, ultrasonic, or other type sensor that measures ride height is prohibited. In addition to standard electronic data measurement sensors, any electrical or mechanical device that may be used to activate, adjust, or tune any engine function based upon ride height, track position, front wheel speed, or suspension conditions, is prohibited. *REVISED 4-4-2011*
ELECTRICAL: Functional charging system, head and taillight w/ brake light, and kill switch required. Headlight and taillight must be retained in stock locations. Turn indicators optional. Headlight is required to be on during all qualifying and eliminations runs. In the event of failure of either the charging system or the lighting system, the tech department will allow repairs to be made prior to the next round of competition. This courtesy repair opportunity is only allowed once per event, per system. Failure by the rider or crew member to activate either the charging or lighting system is considered to be a system failure. Any failure of either system for the second time in the same event will result in an automatic disqualification. *REVISED 4-4-2011* Auto shifters are prohibited.
HEADLIGHTS: Factory headlight systems matching the bike model must be used. All of the original factory glass or plastic lenses must be used, may not be painted or wrapped, and must be mounted in the original location in the front fairing (or headlight bucket on non faired bikes). Non fairing bikes must have the headlight bucket mounted in factory location. All components which are part of the original beam generating and reflecting system, and are visible from the outside of the bodywork, must be retained, and may not be modified in any manner visible from the outside. These components include reflectors, secondary lenses, diffusers, bulb sockets, and bulbs. All such components of both the low beam and high beam systems must be retained, even if that system is not in use. Required components may be mounted in any suitable manner. Any modification of the mounts, housing, or non visible areas of the lenses, reflectors, and other required components is permitted. However, lighting system must be enclosed to prevent the escape of light from behind the fairing or bucket. During competition, either the low beam or high beam lights must be on at all times. Bikes factory equipped with multiple light systems (i.e. left and right bulbs) must burn both the left and right bulbs of the system being used. Unused bulbs do not need to be electrically functional, and a high/low switching system is not required.
TAILLIGHTS: All entrants must have a functioning taillight system, with operational tail and brake lights. Factory taillights are highly recommended. Non factory tail lights must emit red light, and must be sufficiently bright to be reasonably visible.
BALLAST: Ballast is defined as any component attached to any part of the motorcycle, whose purpose is to add weight to the motorcycle. Any component, regardless of weight, which serves a structural, mechanical and/or performance enhancing function, is not considered to be ballast. (i.e., as a general reference, if the component in question can be removed without affecting any functions of the motorcycle, or decreasing structural integrity of the motorcycle, it is considered ballast). Shakedown Tech does, however, reserve the right to deem any non-ballast component to be illegal, if its excessive weight or design creates a safety hazard, or if its construction or implementation is of an unprofessional appearance. Ballast may not be mounted to any bodywork or other plastic or composite components, nor may it be mounted to any part of the riders’ body or equipment. Liquid or loose ballast (i.e., water, sand, rock, shot bags, etc.) is prohibited.
BALLAST MOUNTING: Ballast may be mounted to any portion of the frame, swingarm, seat mounts, rear sub frame, fairing brackets, or any suitable structural component with sufficient strength to safely support the weight of the ballast during the run. Ballast mounting must be sufficiently strong to support the weight of the ballast, as determined by the tech director. All ballast must be mounted within the outer dimensions of the frame, rear sub frame, swingarm, or bodywork. *REVISED 4-4-2011* Ballast may not be mounted to any part of the exhaust system.
CAPTURED BALLAST: Captured ballast is any material or component captured or contained within or around another component without the use of mounting fasteners. This form of attachment is still considered to be “mounted”. This would include pourable ballast, such as epoxy or melted lead,
inside of a tube or cavity. It would also include, but not be limited to, other ballast material contained within welded, clamped, or mechanically fastened components such as inside welded frame or swingarm components, inside a fork assembly, or press-fit into a fork slider tube.
FRONT SUSPENSION BALLAST: No ballast may be mounted to any portion of the front suspension, brake system, fender system, or rotating assembly. Unless specified otherwise, no parts of the front suspension, brake system, or fender system may be remanufactured from exotic heavy materials, including tungsten steel, HD17, or Mallory metal [see EXOTIC HEAVY MATERIALS]. Front suspension components other than the fork leg assemblies and front wheel assembly (this includes triple clamps, clip on’s, fender mounts, brake calipers and hangers, etc.) may be remanufactured from any legal materials, but must be constructed to dimensions reasonable for the application, with hardware reasonably sized for the application. *REVISED 1-7-2011* Whenever possible, OEM components will be used as a reference when determining what are appropriate sizes and dimensions. Lightening holes, gun drilling, and other weight saving techniques utilized on the OEM components may be deleted. Preapproval of custom or aftermarket components is highly recommended. The tech staff has final decision on all front suspension component matters, and will be closely monitoring the use of these components.
EXOTIC HEAVY MATERIALS: Shakedown Tech defines an exotic heavy material as any material with a density higher than 8.1 grams per cubic centimeter. With the exception of components considered to be part of the fork or front wheel assemblies, no front end components may be manufactured from an exotic material. *REVISED 1-7-2011*
WHEELS: Cast wheels must have a 180mm or greater width tire. Wheels 6.75 inches wide or wider must have bead lock unless utilizing Mickey Thompson MCR2 or Shakedown approved tire. Bead-lock highly recommended on all rear wheels. 16 inch minimum diameter front wheels are permitted.
MAXIMUM FRONT WHEEL WEIGHT: Front wheel and brake rotor components may be manufactured from any material. Total weight of front wheel rotating assembly, including tire, rotor, bearings, etc cannot exceed 29 lbs. Inner bearing spacers and any axle spacers not removable without the
use of tools are included in the wheel weight. Any bearing or axle spacers removable by hand will be included in the front axle weight [see FRONT AXLES]. *REVISED 1-7-2011*
FRONT AXLES: Front axle assemblies may be remanufactured or replaced with aftermarket components. No part of the axle or nut may protrude more than .75" beyond the outside of the fork legs. No remanufactured or replacement part of the axle, axle nut, or spacers may exceed 1.50" in diameter. Unmodified OEM parts larger than 1.50” are acceptable. The total weight of the front axle assembly, including spacers, nuts, washers, etc. may not exceed 5 lbs total weight. This weight shall include all OEM and non-OEM parts. The use of lead or exotic heavy materials is not allowed on any axle components. *REVISED 1-7-2011*
FRONT SUSPENSION: Rigid forks prohibited. Hydraulic dampened tube type only, with a minimum tube diameter of 34mm. Front suspension must have sufficient hydraulic damping to allow safe operation. Modifications to existing OEM or aftermarket forks which completely remove or otherwise defeat the function of the damping systems is not acceptable. The design of custom forks must include sufficient damping for the safe operation of the motorcycle under race conditions. All entrants must have a minimum of 1” travel in the front forks, with sufficient clearance around the fender, fairing, headlight, exhaust, etc. to allow the forks, fender, and wheel/brake assembly to safely move across the full range of fork travel at any steering angle. Forks must have enough front spring force to keep forks extended at least .50” above compression bump stop with bike sitting level and rider seated in riding position. Travel is measured from the compression bump stop to the rebound bump stop. NOTE: Having 1” of exposed fork slider DOES NOT guarantee that 1” of travel exists. No more than 1.5” of upper tube (2” on inverted forks) may be exposed above top triple clamp or clip on, whichever is higher.
MAXIMUM FORK WEIGHT: Fork components may be manufactured of any materials. *REVISED 1-7-2011* Fork weight includes all internal and external components of the fork, including the fork oil. Weight does not include axles, axle spacers or hardware, brakes, brake brackets or hardware, fenders, fender mounts or hardware, or any other components mounted external of the fork. Applicable fork weight is determined by the year model of the frame, and not the year model of the forks. Maximum Weight per Side: 1999 & Newer Models: 9.0 lbs. 1998 & Older Models: 12.5 lbs
BRAKES: Operational front and rear brakes are mandatory and must be in safe operating condition. Brake lines must be OEM type or braided steel hose or stainless steel line. Braided steel hose is highly recommended. Brake lines are to be routed and mounted properly to insure no contact with moving parts. Carbon fiber brake pads or disks are prohibited.
GROUND CLEARANCE: All ground clearances are to be measured with the amount of air present in the rear tire at the conclusion of the run. No rider or team member is allowed to alter the pressure, measure the pressure, or otherwise make any contact with either tire valve stem until the conclusion of the post run technical inspection. If an entrant fails the ground clearance inspection and their rear tire pressure has dropped below 8lbs they will be allowed, upon the tech director’s approval, to raise the rear tire to 8lbs and reattempt the ground clearance test.
TURBOCHARGED & SUPERCHARGED: Minimum 3” with rider sitting on bike, straight up perpendicular to ground.
NITROUS INJECTED: Minimum 2” with rider sitting on bike, straight up perpendicular to ground.
RULE REVISIONS: In order to maintain a level playing field, Shakedown Tech will monitor the performance numbers of the numerous combinations and power adders found in this class. From time to time, it may be necessary to adjust the minimum weights, ground clearance, and wheelbase to help promote class parity. Any rule revisions deemed necessary by Shakedown Tech would be officially posted on the Shakedown at E’town website (the rules on the Shakedown at E’town website on the day of the event is in full effect). 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.
MINIMUM WEIGHT: All weights include both the bike and rider, and will be taken at the conclusion of the run.
