Type "Bohmerland" into a search engine.  Something like that has been done.

That bike that Dan Gurney built was interesting.  The Gurney Alligator lowered the seat height to about 18 inches.  Are you tired of the CX-F3 already?

The cbrf3 cx is still not finished and is in Colorado (dans bike).  It is close to ready.

  I am trying to figure out how to reduce frontal area of my own bike.  My orange bike is very big, and the Charlie Toy fairing was stretched wider to get around this huge frame.  It was built for a different plan, twin engines, and it seems I have really run up against a wall with this bike.

I have enough parts to build a better bike, but I need a better plan.  If I build longer, it wont have to be as fat.

Build longer. You know the answer. Your first instinct is always the right one, the second one comes from you know who... :evil:

Sodium Distortion link.

Tried it twice and had to close the program, don't know why or have much of a grasp about computers but just wanted to mention it.

I'd like to know myself about what to expect about the handling of a long bike.

 I'm sure I am going to find out at some point in the game, because I'm starting on a long bike myself, additionally, I am designing the new bike with HCS. I have the Hubs and axles designed and machined, and the parts are out for coatings now. The overall design of the bike is still not complete as there are a lot of things left to decide on that could have an effect the final outcome.

Has anyone have experience riding a bike with HCS, and how does it compare to standard fork set ups.

Back to the Charlie Toy body - and probably most other non-factory bodywork:

ON my ZX12 nitrous bike - which has a Toy body - I discovered that body symmetry from side-to-side is very critical.  He had to widen the body a bit to get the engine all enclosed, and things ended up with the body a bit wider on the left than on the right.  Boyoboy what a "bit" of pull to the left I had.  You're welcome to imagine me on the long course at about a buck eighty-five and darned near dragging my right knee (I was that far leaned over to the right) trying to get the thing to run straight.  Yee-hah, way too much excitement!! :-D

Whatever body you wear on the bike -- do your best to balance it side to side.

Ad for making the bike really long so you can make the front much smaller -- there are quite a few vehicles that have gone that route.  The Poderosa Special of Pappy is a sidecar bike with him laying prone, and even with the sidecar he's well over two hundred.  It's not all that skinny - but it shows that skinny does help.  I can remember seeing others - just can't remember 'em right now.

PS  Yes, it really is spelled "Poderosa" -- there's no "N" in the name.  No, I don't remember why he uses that name.
