Tech Requirements


Technical inspection

Every motorcycle must be certified for racing by the race day technical inspector before being allowed on the
track. The tech inspector will mark each motorcycle as approved after examination, or will tell the racer how to
make their motorcycle ready to race.

If a motorcycle cannot be made ready to race prior to the start of racing, it will not be allowed on the track and
the racer will be refunded their entry fees for that day.

Technical inspectors have final say on whether or not a motorcycle meets technical requirements and is safe to
race. Disputes between competitors on the legality of a specific motorcycle, application of a class rule or
technical requirement, class protests, or concerns about the condition of a competing motorcycle should be taken to
the technical inspector.

Arguing with the technical inspector is not allowed, and may result in other penalties, up to or including ejection
from the event, at the discretion of race direction.

Technical requirements for racing motorcycles

Motorcycles must meet the following technical requirements to be allowed on the track.

Race numbers and scoring

Race numbers 1-5 are reserved for the top 5 ranked riders in the Open Advanced class.

All motorcycles must have race numbers, and numbers must be clearly visible from both sides and the front. 6” high
numbers on the sides and 4” high numbers are strongly recommended. Please try to have numbers as clear and legible
as possible. If a number cannot be read by scoring during the race, the motorcycle will not be scored.

All motorcycles and scooters

  • No visible oil or fluid leaks.
  • Oil drain and fill bolts must be secured with safety wire.
  • External oil filters must be securely safety wired using a hose clamp around the body of the filter with safety
    wire to a hard point on the engine or chassis.
  • Oil filter cover bolts for internal oil filters must be safety wired or tightened and secured with a dab of
    silicone sealant.
  • Footpeg sliders are required for any motorcycle with footpegs. Footpeg sliders should be hard, smooth plastic.
    Metal sliders and fabric wraps are not acceptable.
  • The throttle must operate smoothly with a positive return to idle when released, meaning the throttle snaps back
    to idle immediately.
  • Proper front and rear brake operation and tight bolts (safety wiring is strongly recommended).
  • Only water and Water Wetter are allowed as coolants for water-cooled motorcycles. No glycol-based coolants of
    any kind will be permitted. Engine Ice is not permitted.
  • Vent and overflow lines for oil, and fuel must be routed to an appropriately-sized catch can or cans. Catch cans must be made of metal or plastic, no glass or paper catch cans are
  • Any lights or turn signals must be taped over completely.
  • All motorcycles must be in a safe, ready-to-race condition as determined by the technical
    inspector. This means tires in good condition and no loose bolts, loose parts, loose chains, or any part or defect on the motorcycle that
    the inspector believes may present a safety hazard.

Equipment removal

The following equipment must be removed from all motorcycles:

  • Mirrors
  • Tool kit
  • License plate and bracket
  • Center stand

It is recommended that be removed from all motorcycles:

  • Headlight
  • Reflectors
  • Turn signals
  • Tail light and assembly
  • Horn
  • Side stand and center stand

Additional requirements for full size motorcycles

  • Front and rear axle sliders are required.
  • Bar end sliders or other bar-end protection is required. Heavy-duty handguards or bark busters such as Cycra
    ProBend, Fastway FIT, etc. are strongly recommended. Motorcycles not using heavy-duty handguards will be evaluated
    on a case-by-case basis for adequate protection.
  • Any motorcycles with kickstands that are inside the line of ground impact (DRZ-400, Honda XRs, etc) must have
    those kickstands removed. Kickstands that do not pose an impact risk (Beta, KTM, Husqvarna) must be zip-tied in
    the raised position. If in doubt, the kickstand should be removed.

Additional requirements for minibikes and scooters

  • Front and rear axle sliders are highly recommended but not required.
  • Handguards are highly recommended but not required.

Rider/crew safety equipment and rules


The Cascadia Supermoto series does NOT provide medical insurance. Each rider and pit crew member must have their
own personal medical insurance policy.

Protective gear for riders

It is the responsibility of the rider to wear adequate safety equipment for competing in a motorcycle race.
Technical inspectors and race direction may remove a rider from competition at any time due to insufficient safety
equipment. Riders will not be allowed on the track without all required protective gear.

NOTE: For the safety of riders and spectators, any costumes or similar non-functional/”for fun” attire must be
approved by the technical inspector before being worn on the track.


DOT or Snell certified helmet, manufactured after 2005, undamaged and in good condition, that covers the entire
head (i.e. a “full-face” helmet).

Eye protection

Shatter-resistant eye protection is required (ANSI z87 or better are recommended); either goggles, safety glasses
or a face shield.


Gloves appropriate to asphalt riding. Gloves without abrasion-resistant palms, i.e. thin MX gloves, are not


Heavy boots designed for riding that cover the ankles. MX, Supermoto, or roadracing boots are strongly

Spine protection

Adequate spine protection is required. A hard clamshell-style back protector is preferred, but CE-rated foam back
pads may be allowed if large enough.

Abrasion protection

Full-coverage abrasion protection for the body, including:

  • Abrasion-resistant pants, either leather or synthetic. Jeans or heavy canvas are not sufficient protection and
    will not be allowed unless they have motorcycle-specific abrasion protection (i.e. Draggin’ Jeans, etc) or are
    worn with armor. Motocross pants are allowed with knee armor but not encouraged.
  • Abrasion-resistant jacket or upper body covering. Jerseys or sweatshirts alone are not sufficient; armor must be
    worn underneath.
  • Two-piece synthetic riding suits (Aerostich, Hein Gericke, Motoport, etc) are allowed.
  • Race leathers, either one-piece or two-piece zip-together leathers, are strongly encouraged.
  • Large gaps in body coverage will not be allowed, and no skin should be visible below the rider’s neck. Riders
    should make sure their protective equipment fits before riding.

Body armor

Use of body armor (shoulders, elbows, chest, knees, hips) and Leatt-style neck braces are strongly encouraged but
not required except as mentioned above.

Protective gear for pit crew members and staff

Any person working on the racetrack when it has been declared hot must wear the following:

  • Shirt
  • Long pants
  • Close-toed shoes

Gloves, eye protection, and a long-sleeve shirt are strongly recommended for corner workers and any pit crew member
in hot pit.
