Number Plate colours

[albrid-3]

looking at the GCR, checking on colour back grounds for different capacity, 251-350 should be mid blue/ white numbers, so I will change my yellow back ground to blue as it should,
how many other bikes out there with the wrong colour back ground.

There is no 350 class in VMX Dave. Because my Maico is a legal 350 class bike I had blue plates on it but I was politely told to fit yellow plates unless I was racing in an actual 350 class event.

Trevor Flood always ran blue plates for his YZ 360 ( KB171 has a replica as featured in VMX mag) j

I recall back in the 60`s and 70`s, there was no 350cc class, I was alway lead the believe that if your bike was over size for etc 251 cc  you where authorize  to go to the next colour like blue,  to show that your bike was over 250cc, and that you where not to use that bike in the 250 class.

That was my understanding too Dave. J

I think that I am right, who ever knocked you back mark, doesn't really understand the GCR`s, color coding.

I remember reading somewhere that an open class bike had to above 350cc hence Yamaha 360, Suzuki 370 etc.

I think it was because some one (maybe Dave Bickers?) ran an over-bored, by a few cc's, 250 in open and won. The brand he was riding didn't have an open lass bike

Kiwi rider Ross Horsborough 1973 Aust Title NSW 500 final ,is also legendary for sliping in an extra race.

There was certainly a 350 class in the 60s (at least in WA)

[jimg1au]

there was a 350 class in the 70s as well

And at the 1974 Australian Titles at Manjimup.... Herman turned up with his blue background numberplates.. he was politely asked " did he actually want to race in the 350 class"... little did you realise that, at that event, there was actually a 251-350cc race

Right this is a very grey area.

If you go by 12.6.3.1.

125 is black background white numbers
250 is Green (dark green) background white numbers
350 is Blue background white numbers
500 is yellow background black numbers
750 is white background black numbers (so anything over 510cc (2% tolerance) should be white with black numbers)

There is also different colours for modern MX.

However as far as Classic MX/DT goes the following should be acceptable.

125 black background white numbers
250 Green (dark green) background white numbers
500 and over yellow background black numbers

If someone has got a 350 eligible for the old class I can't see why they can't use blue and white.

Also if someone turned up with a 540 four stroke and had white and black I don't see how they could be knocked back.

My brother race a triumph 650 back the 60`s and his number plate where white, I do know that he also race a f21m which where also white with black numbers.
If I turned up at the Australian Vintage titles with my maico and the number plates where blue, and raced it in the pre 70 class, that should not be a problem

I just going by what is currently in the MOMS. Unless the supp-regs state different you should be allowed to do that, but I won't be the scrutineer.  Be prepared to argue the point.  But please note the heading of the listing says Capacity or Class.

So is the plate colour for the Capacity of the bike or the Class it is racing in.

All that I know is I have now made a mental note for myself to put the plates colours in the supp-regs for the Post Classic Championship supp-regs.

Sorry I thought it was simple until I saw the Capacity or Class bit.

Blue background white numbers is also used for 251 to 450 four stroke Dirt Track, under 9 year old juniors and WEM use it for the Under 19s in the Aust MX Champs.

Wasn't it also the case for AMA supercross races, that 250cc bikes ran white backgrounds with black numbers ? I am not sure if this was an FIM approved ruling and therefore applied to Australia as well. I always had green background plates on my 250cc bikes, even in the few supercross races that I rode in .
