If you were to swap all the components off an 85 model bike onto an 84 model frame (assuming they fitted) would the bike be eligible for pre 85 racing? ie. is it the age of the components or the frame number that determines eligibility?
Or to take another angle are we getting into dodgy ethical territory?
-
depends what model you are talking Mainline. If in effect the parts from the '85 are unchanged from the '84 then yes but if the parts are say upside forks instead of conventional then no. The parts must remain within the period!..some '85 stuff is quite legit but only if it is the same as the '84 part being replaced.
-
I know for the post classic road bikes eligibility is based around the period date of major components. Applying the same logic,(and if the same approach applies), if the major components were pre-85 then you would be ok. If you had 85 or later major components and could prove they were the same as pre-85 models you might also be OK e.g. wheels and brakes etc. If the major component is 85 or later and it is different to the pre-85 models I am guessing that there may be grounds for appeal.
I don't know if this concept/rule applies here under MA rules and what has been defined as a "major component" in terms of MX bikes versus road bikes (or if the same applies across the board).
I will be interested in other replies as it seems there is much more scope for modification in the MX area than what would be permitted for a PCRA road bike.....
Mark (others??) help me out here...... ???

Thanks guys,
Does anyone have any knowledge of the differences between 84 and 85 KX125's in particular? I think I'm on a dead end road here with the frame swap issue but I just thought I'd ask.
Cheers

I have a shootout issue of dirtbike mag from 1985 where it explains the differences between 84 and 85 KX125's , mostly it deals with the introduction of the kipps power valve system. other than that most stuff is interchangable (body work, airbox, radiator etc) Unfortunately both the front and rear ends didn't rate well for either year.

Mate, what would be the chances of getting a scan of that article??????
-
In a nutshell the short answer is no. Rule states that pre85 is for bikes made up to and including the 1984 model year and or components available in the period. Components that are of a later year must be considered identical - not similar- identical to be considered follow-on and in most every case the onus of proof will remain with the entrant. In the absence of proof I would argue to leave the bike a 1985 model rather than bust it up and hope.
The old story that says read the rule book first before you build the bike holds true here - don't build a bike and try to argue your case, build a bike that fits the rules and have no argument. :)

Not sure how long the pre '85 class has been in existance but given that it is now 2008 is there any chance that we might see '85, '86, '87 model bikes being permitted in the "vintage" class.
On what basis is the vintage MX class determined eg was it established for bikes older than 20 or 25 years? Is there any requirement to periodically review it?
-
Just don't mention the war!
Short version is that pre-90 is either happening (eg: Vic) or has been recently discussed but is still not happening (eg: NSW). Even in NSW, a few of us have been gathering together pre-90 bikes for our own reasons (not unlike the guys who collected pre-75 bikes in the mid-1980s....) but are not holding our breath for a class to get off the ground.
The ACT club runs an 'old school' class for bikes with rear drums, non-USD forks.

Why do people keep wanting to move the bloody goal post ::) There is a post 85 class its called MODERN MOTOCROSS :-X

Yo Bill. ;D

YEp have to agree on that one walter. YOu cant reinvent the wheel and call it a pencil
-
Why
Because when you are on to good thing some one will allway want
to change it .
In 1998 I was Racing My Ktm(1976) with the Moderns in the Over 35 years
class In the A.C.T .
So then I and the A.C.T.M.C.C started vintage racing in Canberra back in 2000
It was Evo Both MX and DT.
Then Mx went pre 85 to Boost Numbers.
Dirt track stuck with evo Twin Shocks , Air cooling , drum brakes Only.
Now Mx has move to "Old School " With New Rules ???????
-
"Old School" to me does Not mean discs front and back,cartridge forks, power valves etc etc-not my old school anyway.I think the Canberra "Old School" Class is a misnomer.
-
Meh.
Given that HEAVEN recently rejected pre-90, and the widespread acceptance of that decision by the pre-90 advocates, I'm amused by the continued vitriol whenever pre-90 is mentioned.

Well logic would seem to dictate that it's gonna happen one day....just a matter of time... ;)

It already is ;) ITS CALLED MODERN MX just turn up at your local modern meeting and enter :D if your any good as a rider you wont get left behind and all those young hairdressers at modern meetings can go "WOW look at bloke on the old bike go". After all your pre 90 bikes are a much closer relation to todays bikes than they are to proper vintage bikes but the majority of the modern set wont know that ;)
