Can you somehow connect two RRs together and put a seat in the middle?  Would it be faster than just one?  Any engineers willing to participate?

if you could get the shift linkages right, why not just do a quad?  it'd be a hell of a lot less engineering and fabricating.  on a side note, a buddy of mine and i have a really bad idea:

costco shopping cart + quad = bad decision but fun!
too close for missiles I'm switching to guns!

1 With enough time and money you can do just about anything you want.
2 Probably not, unless you can significantly decrease the mass being accelerated, or you can decrease aerodynamic drag by a bunch. You may need to better define what you call 'faster.'
3 Yes. I have my BS in mechanical engineering.
* You are going to encounter some stability problems if you try this. See the causes below.
  i asymmetry of propelling forces
  ii high center of mass (a problem if the vehicle is not designed to lean.
  iii Ackermen (spelling?) and other complicated properties of steering a four wheeled machine.
  iv Laterally unbalanced  mass.
  v Other stuff I don't have time for here.

I see what you mean about turning.  I bet it could do some sick wheelies though.

I think that it was on here that I saw a pic of a quad hayabusa....
what a waste!
I guess he found the solution to keep it from flipping.... :-X

Yeah but I am talking about actually welding two bikes together with a little cockpit in the middle for the pilot.

wait a tic.....sti motor = 300 hp...cart = probably around 800 pounds...

that's scarier than my shopping cart on a quad frame idea
