1995?? I'm confused

The sport or hobby those of us on this forum generaly share is vintage dirtbikes , bikes from a bygone era with all their spindly frames ,underwhelming brakes and tempremental habits .
When racing these old girls we are governed by a set of rules aimed to keep an even playing field and maintain the integrity of that era.
Since the early days of VMX we now have classes right through from year dot to (in some places ) pre 90, so something for everybody .

There is a huge chasm of development ,quality control , materials etc between the earliest and latest eras in which we race and if you still want more theres modern MX .

So my confusion is how could these new generation frames with their perfect geometry and modern welding techniques be considered for the earliest classes of vintage racing .

If you so desire to race something that handles so much better than an old Mettise in VMX then why not ride a pre 90 bike .

Im concerned that if this sort of frame and other componentry is allowed into pre 65 racing then the magic of that era will be lost in a short time and replaced with a plastic version .

Not VMX but based on your argument you'd better contact the historic road racing register and have them outlaw all those Manx and G50 replicas. That'll be well received...

It's a unit construction ESO motor, built specifically for motocross - quite rare. Look up "Black Betty" in the forum Kerry.

Which part of "unit construction" are you stumbling on?
