monocoque flat tracker.
« on: October 24, 2012, 04:13:53 pm »
 Here's a unique flat tracker. I believe these monocoques were made in California in the early seventies. It looks like a later Kawasaki swingarm R6 forks and YSS shocks are later additions. She's not the prettiest girl in the class. ::)

A WW2 fighter plane paint job would look good.

Looks like someone built a fuel tank, then could not afford a frame, so they attached a motor to the tank.  ;D

Pig ugly but interesting, thinking outside the square.
Actually, he used his square too much.

Here's a RT2 powered version which I reckon would have been the trickest thing on the planet in 1974. This (and I suspect the above flat tracker) were made by a guy named Don Haagstadt in Brisbane California.

 Thinks they (especially the RT one) would be certainly lighter than some other after market flat track frames. Just not as awesome as Hagon's or Egli's alloy beauties.

I may not agree with what you have to say, but I'll defend to the death your right to say it.

This is Alan Jones' VE Hagon Yamaha 500TT monocoque. It's much lighter than it looks and works pretty well. Alan also has Hagon LTR monocoque speedway and grass track tackle.

Mark, were the rear pegs and duck on the swing arm standard Hagon equipment on that model?  :D
