I will take it you mean to answer vintage me is "pre '75"
No,
I posted the link up so people can re-read what has been said on the subject, and also if some(posters') have changed their minds.
I personally like the idea of 'vintage' being ''Twin shocked'' motocross bikes. 2 shocks on a motocross bike is starting to become rare in these modern days. For what its worth, I think that Suzuki started off the modern suspension system as we know it today with the 1981 RM's, which made 2 shocks dated over-night. Thus, helping Twin-shocked bikes being able to take on the word, "Vintage", under the banner of Vintage Moto-X.
I'm not saying that all the era's in the twin-shocked periods' are vintage bikes, as I believe what 'Doc' has written in this thread about the different periods within the twin-shock period, except that I would say that the twin-shocked Evo class is "Modern-Vintage". There by show casing the history of moto-cross racing with twin shocks.
You know, maybe it IS time to really get this issue sorted. IF we could agree on the format for VMX for the next decade, how would we go about changing it? I'd be keen to get the debate happening here, and to use 2009 as a time for pounding out the rules to satisfy most, and then see if we can implement for 2010 or 2011. It'd be good to set it in place for 2011 on. If anyone can tell me how we'd do it, I'll start a thread to do the actual discussion. I know it'd be painful, but challenging and ultimately worthwhile. I really want to enshrine VINTAGE and make Pre 85/Pre 90 a formal set of classes that have their own separate and unique identity.
I agree with what Graeme M is saying about the different types/styles of motocross bikes needing definitive periods all under the one name of "Historic Motocross", but broken up into different periods, which would give the linkage suspension bikes a chance to name their own racing/events/meetings/clubs etc, but all under the one big name "Historic Motocross".
The twinshock bikes could race as 'Historic Motocross; Vintage MX' bikes
and the Linkage bikes could race as 'Historic Motocross; Evolution MX' bikes
Both types of racing would have classes within their periods and of cause the Evolution MX could include Pre90/95 classes like "1st Generation linkage", "2nd Generation Linkage" and what ever classes they feel are needed.
