Well I had my little 'bitch' early on in the thread, so now its time to address some of the points raised so far, which have been mostly thought out and well written, but I was on the understanding that VMX (Vintage Motocross) was about aircooled, twinshocked, drum braked bikes and to a lesser degree (but nothing taken away from them) the evolution, from the start of motocross/scrambles to how they became the modern bike with Linkages', water cooling and disc brakes. Now with that said, the perfect cut-off to show case Vintage Motocross is classes' going from the early years up to pre85 or pre86 (as we have in NZ). This is what Vintage Motocross is about, not a "moving era of time" for people to pick and choose what class(es) they would like to race a motocross bike in. Yes, the VMX scene is full of great people, but lets not forget that "we as people move on", our bikes remain the same, therefore so should VMX. Before you start to argue that numbers will decrease, that is only if we allow it to happen. Through promotion, dedication and a willingness to allow younger riders the chance to race these older bikes I believe there isnt a need to move the (VMX) era. Most of us have already stated we just want to ride dirtbikes (any dirtbikes), so why do you think the younger guys feel any different?? If they are given the opportunity, most have a blast because its still racing. I believe VMX isnt a commodity that should move with the times but more a "state of presence" and have the people move into the time of VMX. West Oz don't seem to have a problem with filling start gates with pre75 bikes. If VMX is an era in time, then lets keep it that way. Otherwise the sport of vmx may as well be called "Twenty-year old Motocross" for tight-ass cheapskates that wont buy new bikes.
No matter what you or anyone else says, VMX is still one of the cheapest forms of motorsport so that arguement about the cost is irrelevant, and as for a pre86 bikes not being able to match a modern bike, I know of a few good riders who have taken honours on them right up to national level here in TT races, to the point of prefering to ride a '85 CR500 than a new 450 4 stroke. I except that on a modern man-made motocross track a pre85/6 bike would be left wanting but when all things are equal these bikes are as modern as Vintage Motocross need be.
Are we, as Vintage Motocrossers' preserving bikes in an era in time or preserving the racing of old bikes??
