What is the Black Cavier equivalent vintage (old) motorcycle on Flat track

[52]

Forgive my ignorance on the subject of US flat track, but am I correct in saying that whenever a different make of bike began dominating the Harleys , the rules were changed to either ban them (as in the case of the Roberts TZ) or move them to another class (as with the Rotax powered bikes) ? I think that the Rotax powered flattracker in this pic, shown as an example, was John Kocinski's race bike.   

That is a great shot of Kocinski's bike, is that recent? Jerry (John's dad) was building a new one for John to ride in Kansas, I felt the weight of the pipe and glass, super-light. It may be the same. The aim was to produce the lightest Ron Wood bike ever.

Kocinski's two stroke mount is a real beauty as well. They build nice bikes that's for sure. Here is a good example of how to ride a two stroke consistantly.

That Ron Wood Rotax of Kocinski's is as trick as my old Nana's pumpkin scones. Check out the underslung Ohlins shock, P&M wheels and lightweight carbon fibre 'glass and titanium everywhere, the bike just oozes dollars.  Kocinski could of course win on a bog stock dungmobile but why not have the baddest vintage racer out there if you can.? Does it race in the vintage classes Pete?     http://www.superbikeplanet.com/image/archive/jkrotax09/

Again, sorry for butting in but what Vintage class does that trickery fall into?
Excuse my ignorance of all things Flattrack.

 If you're refering to the rear suspension Slides, it looks a lot like a friends N.S.U from the early fifties.

Everything old is new again?
You'd know more about that than me Punchy.
It is a great looking thing though and I'd love to throw the leg for a few laps.
