To achieve the excellent neighbour status there will be changes during "Tech Check In" on the following events:

• Motorcycle Road Race Days (EMRA)

• Track Attack Motorcycle Track Days

• Motorcycle Super Moto Days

Tech check will now include a sound test. All vehicles will be tested using the Standard SAE J1287 test. 99.9 db at 20 inches is the maximum sound allowed. Most Super Motards bikes will meet this requirement with a well packed stock silencer. Many vintage bikes, bikes with blown-out silencers and some two strokes will not pass the sound test and will not be allowed to be ridden at Stratotech. If your bike does not pass the sound test, there is no charge.

Do not alter the exhaust after the sound test. Just one loud vehicle could doom Stratotech Park from remaining in operation. If your vehicle is making excessive noise on the track, you will be asked to repeat the sound test. If your vehicle fails the re-test, you will be prohibited from the track and will not receive a refund.

RACE CLASSES AT STRATOTECH PARK

Sportsman
Motorcycles (Chassis & Engine) must be at least 10 years old and major modifications are not permitted, as these machines are required to meet the technical requirements of the Supersport class.

machines.

SV Cup
This class sees riders mounted on stock Suzuki SV 650's. The only modifications allowed are stock appearing aftermarket bodywork and aftermarket exhaust systems and racing tires.

All Sportbike classes are designed to keep motorcycles close to the original manufacturers design. No modifications are allowed to the internal engine components. All frame dimensions must be equal to the original design and apart from removing turn signals, rear foot pegs and other minor items; the appearance of the machine should not be changed.

• This is a women's only class.

Super Moto
Motocross style motorcycles with some modifications. Seperated into two classes based on wheel size and experience. This is a high speed lower cost alternative to sportbikes when roadracing. These bikes are very fast and require great skill to control on asphalt type surfaces. This is probably one of the fastest growing motor-sports in the world due to the close racing nature and unpredictable outcomes.

The National (or Provincial) flag is used to start a race only.

The green flag indicates that the track is clear pass your station. It is held stationary while the corner before you is on any kind of yellow flag.

The yellow flag Stationary – Indicates that there is a situation that requires caution on part of the rider. This flag is used if the people or equipment involved in the incident are not in target line for any rider. Passing is allowed under a stationary yellow flag. Waved – Indicates that there is a situation on the track that requires extreme caution on the part of the rider. This flag is given if the people or equipment involved in the incident are on or near the track, or if they are in the target line for another rider (should they also go down). Passing is not allowed from the point on the track next to the waved flag, through to the incident. If the incident is off, but near the track, then the riders cannot pass until they are beyond the point on the racetrack next to the incident.

Adhesion flag. Advise drivers to take care. Used to indicate a slippery surface such as the presence of oil, water (during a dry race), and or debris on the surface.

The black flag indicates to a rider that he has been disqualified, penalized for an offence, or has a problem with their bike. If able, the rider should proceed around the track and report to the starter the next time he/she approaches the start finish area. The rider may be allowed to continue depending on the infraction.

The white flag identifies to the riders that there is a service vehicle on the track. This may be an ambulance, tow truck or any other vehicle authorized on to the track by race control. The flag will be held stationary when the vehicle is prior to a corner, and will be waving if the vehicle is beyond the corner.

The last lap flag displays as the race leader starts his final lap. The flag displays until the race leader takes the checkered flag.

The checkered flag indicates that an event is complete. As competitors take the checkered flag, they complete 1 cool down lap and exit the track. In some instances, an extra “victory” lap is allowed for the winner of the event.

Blue and green flags are displayed furled and crossed, at the start finish line, halfway through an event. They are displayed for 1 lap only.

The red flag is displayed on all corners when an event needs to be stopped. It is the responsibility of all racers to stop racing immediately, slow down, exercise extreme caution, be prepared to stop, and proceed to the start finish line when directed to do so by the track marshals.
