This is with the intention of recreating as far as possible the sight, sounds, and spirit of Grand Prix racing in the late 1950's and early 1960's for both rider and spectator alike while, at the same time, maintaining a viable event for the host circuit/club.

The series is an invitation only event but in order to give competitors and potential competitors a guide as to what would be welcome to the Series, a statement of machine requirements can be found via the links for "download" and "Technical" above.

General

Riders

Machine Requirements

1. From a distance of 10 paces, machines must be of an overall appearance that accords with the period and all cycle parts must perform the function they were originally designed for.
2. External engine parts must conform to a design & specification readily available from the manufacturer to private buyers up to the end of 1963. (In the case of Manx Nortons, this is to 31st December 1962 and by special exception 250cc/350cc 'long stroke' wet clutch Aermacchi's to 1964). In particular, all external castings must look original and be of the original type of material and dimensions although magnesium may be substituted for aluminium.
3. Pre 1963 specials (eg the McIntyre Matchless and works machines) must be of European origin and be substantially the original machine (i.e. not a replica). Proof of provenance is on the rider
4. Replicas of 3. may (at the discretion of the organisers) be permitted to race if the original is not racing in the series and the bore & stroke does not infringe 12. below. This concession is with the particular intention of allowing machines to race of notable technical merit e.g. an Earles fork Manx Norton.
5. No fairings (either full or half) although flyscreens are permitted (if ACU legal).
6. Pre '63 original fitment drum brakes only. On the front wheel there must be no more than 2 leading shoes on either side.
7. No carbon fibre or titanium parts.

Machine Requirements

8. Exhaust pipes: Low Level (where used) must follow the original route which for most Lansdowne machines (eg: Manxes, G50’s, 7R’s) will be from the cylinder head, across the timing chest and exiting under the rider’s off-side footrest; low pipes must also be of a constant diameter from the cylinder head to the mid-point of the gearbox. High Level pipes (where used) must accord with ACU requirements. Stepped or tapered High Level pipes are permitted but will be handicapped accordingly.
9. Unless the Regulations state otherwise, the ACU noise limit of 105Db applies to all Lansdowne races. There must be no changes to the silencing system after passing a noise test such that the machine is then used on the track outside the permitted limit. Contravention of this will as a minimum result in a zeroing of all championship points in relation to that meeting.
10. The following departures are allowed in the interests of safety and pragmatism
    • Belt primary drive along with aluminium or fibreglass guards/covers.
    • Silenced exhausts to ACU standards (obligatory at most meetings)
    • 5/6 speed gearboxes if fitted in the original style shell, free choice of ratios
    • Enclosed valve gear
    • PAL and other types of magnetos are permitted as long as they have mechanical points. Electronic circuit breakers will be handicapped accordingly.
    • 18" wheels although 19" wheels are encouraged under the handicap.
11. All bikes are subject to a handicapping system which adds or subtracts Championship points for particular features. Details of this can be found via the "handicap" button on the main page.

Production (road based) engine racing machines

• genuine Clubman Goldstars (in racing trim)
• "Tom Phyllis" Domiracer replicas
• Other road based machines may be permitted to race on an occasional basis at the organisers sole discretion, but not for points

Fuel

1. Alcohol based substances (petrol sourced from pumps at main-stream petrol filling stations containing ethanol does not fall within the scope of this restriction, excepting E85)
2. Oxidizers of any description.
3. Any substance prefixed "nitro"

Grid Formation

• Row 1 - 500cc only
• Row 2 - 500cc only
• Row 3 - 350cc and 500cc machines alternately
• Row 4 - ditto and so on until end

Protests

1. Obtain the support of two other competitors racing in the same race
2. Politely notify the competitor alleged to be in breach and seek to resolve the matter privately, in the presence of the other two competitors.
3. Failing agreement, submit in writing to the organisers within 1 hour of (2) taking place brief details of the protest (and any defence offered) signed by the protestor and the two other competitors.
4. The organisers will invite all parties to submit written evidence in a prescribed form and time scale. Based on that evidence the organisers will adjudicate. Any protest upheld could (at the organisers discretion) ultimately result in the rider concerned being excluded from the Series and forfeiting all points and entry fees. The organisers decision is final and binding.
