Wow, good find.
I thought that was a Vincent.
Sure does look like one.
What was this, a one off or something?
He was a player in the 80's for a bit in the motocross world.
His stuff, the mx stuff, if one can find them, are super rare and expensive.
Mugen, they we're trick.
Looks like he was like his Dad, when he went racing, he went racing.
The guy in the following article, Johnny O'Mara, really
was the guy that transformed old school motocross to what it is today.
He was the guy that when confronted with 2, maybe 3 big jumps in a row,
just pinned it and cleared all of them.
Before Johnny O, doubles and triples, or guys that did them, just didn't exist.

I mean...they don't criss-cross...when you apply power to them wouldn't they try to just flex instead of pushing the bike forward??? same thing on the front spokes when you jump on the brakes. Strange.
