It actually does depend on the situation, at least here in Queensland. It is of the opinion of some, at say for e.g. a club day you turned up with an rm125b. Then you could in theory ride pre78,evo,pre85 and pre90. That is not encouraged as it makes the races a dogs breakfast. This has been thrashed many a time on here where others that think its all bureaucracy gone mad. For me it's easy, we have era based racing so keep it like that. If you're too tight or too lazy to prep/clean a second bike, or not financially able to buy a second bike then that is your situation and not everyone else's .If one can do it, everyone can do it. Vmx is more than just bums on seats. This way it actually encourages more bikes to be seen/ridden/bought back to life.
But in the case of your particular question re the post classic nationals, you will be accepted with your rm125b in evo.
why thank you Mr donald trump-van barello...
your latest promotion to CEO of media relations has come as a surprise...
your quote someone to lazy ( or works 2 jobs to support a family/ sole parent etc etc) or is financially challanged should in your words SUFFER because of your opinion its messy..
at least you waited till after australia day to be un australian...
you could enlighten us n put up a link to the ruling that states a DT1 for example can't compete pre 90...
it was manufactured pre 90... so if someone wants to handycap themselves whats the problem
some people,, myself included would rather eviserate ourselves with a rusty spoon than have a shed full or german scrap metal...
John seeing as you are such a super patriot, I would have thought that you would at least have the decency to write it as Australia day and un Australian
However you could be forgiven for the german
I used to struggle with the fact that you cannot ride up a class , but Brads point has merit .
It is era racing and although you could ride an older bike back in the day or even now at modern events , as Brad says its about era racing and a bike from out of that era looks out of place with later bikes .
As for getting on your high horse about families , 2 jobs etc Boo forking hoo
we have all done it ,and its about prioritising or working harder to afford things if you want them .
Its a sport not a charity for broken arses
and sports have rules , like it or not
