Track Racing Changes for 2019 Handbook

Monday January 21, 2019 at 12:39pm

Following a complete review of the Track Racing Standing Regulations, the ACU Track Racing Committee has made the following changes for 2019:

1.7 ADULT TRACK RACE RECORDINGS  

This is different from last year, as points rewarded for winning the final now DO NOT change regardless of the number of overall competitors entered into the class.

At all ACU Grass Track events, points will be allocated to competitors finishing in point scoring positions. Standings in the National Grading lists will be used to decide competitors for the 250cc and 350cc Solo, 500cc Sidecar and 1000cc Left Hand Sidecar British Championships.
The British Masters Qualifier Championship will not be awarded grading points.
For all Grass Track events, the following points will be awarded in each class:
1st = 6 points
2nd = 5 points
3rd = 4 points
4th = 3 points
5th = 2 points
6th = 1 point.
Points are allocated on the results of each class at each event. In classes where there is more than one Final, points will only be allocated on the results of the first Final.
Where a competitor rides in more than one class, they will score points for each class. These points are not transferrable between classes.
Points will not be allocated in an ‘Unlimited’ capacity or ‘Open’ classes, with exception of ‘Upright’ Solos and ‘Pre 75’ Solo classes. In these classes, ‘Unlimited’ and ‘500cc’ results will be combined. There will be no Grading List for 250cc or 350cc Upright or Pre 75 classes.
Results are declared by the Clerk of the Course. They are either decided by a one-race Final, or by point-scoring legs.
The conditions of results must be listed in the race programme. In the result of a tie, it is at the organising Club’s discretion how ties are decided.
Points will only be awarded if results are declared after no less than two heats per competitor.
All National Grading lists will be published online throughout the season.
At the end of the season, results will be compiled, checked and cross-referenced with the Centre Recorders to ascertain the final standings.



 

1.8 YOUTH TRACK RACING RECORDINGS

This is a new addition for 2019.

At all ACU Youth Grass Track events, points will be allocated to competitors in accordance with their finishing positions.
Points will be used to form the National Grading list for these four Youth classes: (a) Auto-Cadet,
(b) Cadet, (c) Juniors and (d) Inters.

Competitors who ride in more than one class will score points for each class, but points are not transferrable between classes.
All Youth competitors riding in an event will score points. However, competitors must complete in least one race to earn National grading points.
Points are allocated based on the number of competitors in the event. For example, when 5 riders compete, points will be allocated as follows:
1st = 5 points
2nd = 4 points
3rd = 3 points
4th = 2 points
5th = 1 point.

2.19 LEAVING THE COURSE/CUTTING THE COURSE

This rule has been completely reworded. Last year it read as ‘The Clerk of the Course may exclude a competitor(s) who permits a wheel/wheels of his/her motorcycle and/or sidecar to cross the defined edges of the track, or who displaces marking flags with motorcycle/sidecar or any part of the person, unless such action was taken in the interest of safety or due to the action of another competitor.’

Any competitor(s) whose motorcycle crosses the defined edges of the track markers/white line – with any wheel – will be disqualified unless, in the opinion of the Clerk of the Course, the action was taken in the interest of safety for other competitors, or the competitor involved was forced ‘off course’ due to the actions of another competitor.

2.21 RIDERS PRESENTATION LAP/WINNERS LAP OF HONOUR

This rule is a new addition for 2019.

No unauthorised passengers (children, wives/partners etc.) are allowed to ride on a competitor’s motorcycle at any time during the event. In exceptional circumstances, an organiser may apply to the TRC for dispersion to this rule.

2.26 RIDERS Concussion/suspected concussion

Rewording of the section below.

If a competitor is involved in an incident which results in him/her being diagnosed by the Medical Officer/Paramedic as suffering from concussion or suspected concussion, the competitor is not permitted to participate any further in that event.
Organisers are to notify ACU Head Office as soon as possible of any concussion/suspected concussion injuries and then will subsequently:
a) Place the competitor on the ACU Stop List
b) Inform organisers of forthcoming events that the competitor has suffered a concussion or suspected concussion injury and is therefore placed on the ACU Stop List

c) Inform the competitor that s/he needs to see a Doctor and obtain a letter/Doctor’s certificate which confirms s/he is fit to resume competitive racing/participate in a practice/test session.

The recovery time for anyone diagnosed with concussion or suspected concussion is as follows:
a) Over 20 years: Excluded immediately and suspended for a period of nine days.
b) 16–19 years: Excluded immediately and suspended for a period of twelve days.
c) 15 and under: Excluded immediately and suspended for a period of twenty three days.
The competitor is not permitted to ride during the obligatory suspended periods outlined above and then only once s/he is in possession of a Doctor’s certificate/letter after the suspended period has expired.

If a competitor has been injured on a Saturday and is suffering from concussion or suspected concussion, and the organiser is aware that the competitor was intending to ride or is scheduled
to ride somewhere else the next day, the organiser will inform the organiser of the event being
held the next day so they are aware of the competitor’s injuries and as such s/he is prevented from participating in that event.

4.4 MUDGUARDS AND WHEEL PROTECTION

The section below has seen changes in the weight used to measure the Dirt Deflector tension. For Solos it has changed from 4kg to 8kg (Long Track and Grass Track).

Category 1, Group A and B motorcycles must be fitted with two mudguards giving protection to the driver. The rear mudguard must extend laterally beyond the tyre and cover at least 35 degrees of the upper front quadrant of the rear wheel, and must extend to 5 degrees or more behind a vertical line running through the rear wheel spindle and must extend to the full width of the tyre. The Clerk of the Course may permit the removal of the front mudguard if conditions make this desirable. If cast or welded wheels are used for all types of Track Racing a protection must be provided by enclosing the spokes with solid discs. The Sidecar wheel mudguard must extend to the full width of the tyre. For all Solo machines FIM Homologated dirt deflectors may be used. The lower edge shall be 35mm maximum from the track surface over an equal distance. To measure the tension by the machine dirt deflector, a vertical balance shall be used to measure the equivalent minimum pre-load of 8kg for the dirt deflectors used for Long Track and Grass Track Solo machines and 6kg for 1000cc Sidecars. The vertical balance must be attached to the outer edge of the dirt deflector holder plate in line with the centre of the rear tyre. All measurements are taken with the machine in a vertical position, with the tyres normally inflated without a rider.

If ‘Huggers’ are fitted to protect the rear wheel of Solo machines competing at ACU domestic events, they must comply to FIM regulations and be mechanically fitted to the machine.

4.7 FOOTRESTS AND HANDLEBARS

The change to the section below has been highlighted in bold

The footrest for the driver must be positioned to give easy access to any control pedal. The ends of the footrest must be rounded with a spherical radius of not less than 8mm viewing from front and end of footrest. The ends of the handlebars on all motorcycles shall be rounded or protected. Footrests must be mounted on an independent pivot.

When light alloy handlebars are used, the distance between the two extremities of the clamping area (or of the two clamps) must not be less than 120mm and handlebar clamps must be very carefully radiused and engineered so as to avoid fracture points in the bar.
Handlebar width (Solo machines)

85/125 Min 650mm Max 850mm 250/350/500 Min 700mm Max 900mm

The use of fuel additives is prohibited, with the exception of oil for two stroke engines.

Fuel injection is permitted.
Fuel tanks must be constructed of a material that will neither shatter nor splinter upon impact.

8.6 EXHAUST SYSTEMS

Exhaust pipes and silencers may be of a “baffle” or “absorption’’ type and must fulfil the requirements concerning noise control.
An exhaust extraction (megaphone types) effect must not be caused by the positioning of any tapered, conical or other shaped parts.

The exhaust pipe must be fixed to the cylinder head and frame with a minimum of three clips (the point of fixture at the cylinder head is considered as one clip). The silencer must be fixed to the frame with at least one clip.
Additionally, a second flexible coupling must be fitted from the first third of the silencer to the frame (steel cable of at least 3mm diameter for reasons of safety) or a solid steel spring.
Exhaust fumes must be discharged towards the rear but not in a manner as to raise dust, foul the tyres, or inconvenience a passenger, or any other riders.
The entire exhaust system must be contained within the fairing, to ensure that the exhaust system cannot come in contact with any rider, passenger, or other motorcycle.

8.7 WHEELS, RIMS AND TYRES

The front tyre and Sidecar tyre must be of a ‘trial’ type pattern.
Maximum sizes for rear wheel rim: 5.00" × 19".
The Sidecar wheel diameter must be between 16 and 19 inches and must camber inwards. Cast or welded wheels must be covered with a disc or other suitable shield.

On level ground the maximum incline of the Sidecar wheel must not exceed 25 degrees, with the Sidecar being fixed rigidly to the motorcycle
The Sidecar wheel can be mounted with plates on both sides. If this situation exists the spindle diameter must be min. 12mm. If the Sidecar wheel is mounted with a bracket on one side, the spindle diameter must be min. 20mm.

Any open area in the Sidecar platform inside the continuous crash bar, and on the running board on the near-side, must be filled with a suitable material to prevent either the rider or passenger from trapping their feet.

8.9 DIRT DEFLECTORS, MUDGUARDS, FAIRINGS

A dirt deflector is compulsory and must be of a type homologated by the FIM. The dirt deflector flap holder must be constructed of a non-metallic material.
The dirt deflector must be fitted adjacent to the rear wheel and is required to deflect “wheel-spray” or track surface material downwards in order to minimise the inconvenience caused to other riders, spectators, and the soiling of track-side notices and equipment.

The return mechanism must have a minimum pre-load of 6 kilos (to be monitored during the season and reviewed if required). The lower flap edge of the deflector must be 35mm (±5mm) from the track surface.
The dirt deflector arm must be modified to ensure that the blade and flap are correctly positioned behind the rear tyre.

A rear mudguard must be fitted, and extend from the rear seat to a maximum of 150mm from the ground (when the Sidecar is laden).
The outside of the Sidecar wheel and tyre must be covered by a non-rotating shield or fairing. This fairing must be securely fixed to the Sidecar and outside of the crash bar.

All fairings and nose cones must be constructed of fibreglass, plastic, or similar material. They must be smooth, free of any sharp or protruding edges, and must not provide a danger to any other competitor. The minimum clearance between streamlining and the ends of the handlebars or their attachments is 30mm with the front wheel in any position. No aero foils or similar devices are permitted.
No part of any nose cone or fairing may extend beyond a vertical line drawn through the leading edge of the front tyre. No part of the Sidecar fairing may extend beyond a vertical line drawn at a tangent to the rear edge of the back tyre.

Throttle controls must be self closing when not held by the hand.
The throttle must be controlled by cable only; no ‘fly bye wire’ type throttle actuation is permitted.

Rider aids, whether part or full system fitted on a motorcycle/engine CANNOT be used and are not permitted.
An ignition cut-out must be fitted on the handlebar, as close as practical to the throttle.
The switch must cut off the circuit of the electrical supply by the simple action of pulling a lanyard or a non-elastic cord (with a maximum length on 30cm), attached to the rider’s right wrist.

Note: Interrupting the electric supply by grounding the circuit is not a sufficient measure.
The ignition cut-out lanyard must be attached to the operator’s wrist when the engine is running. Ignition cut outs will be checked prior to practice to ensure they function correctly

8.12 MEETING FORMAT AND REGULATIONS

Details of the meeting formats and associated meeting regulations will be confirmed in the form of Supplementary Regulations that will be issued by the ACU TRC prior to the start of each seasons series.

SECTION 9 YOUTH

Changes below have been highlighted in bold.
