I own a Futura and it is pretty close to my dream bike. I've owned ~20 bikes and ridden a lot more (from Goldwing to XX to CBR400RR to shadow) , so I am getting closer.
Color: Blue, minimal graphics
Displacement: 990cc or greater (GP rules) with 120-150 HP
Engine Config: V-twin or V-4 (crowd pleasing exhaust note)
Ram Air is not necessary
Single Swingarm (on the fr also would be nice a la Honda NAS)
Hard lockable Bags that don't detract from styling and easy to remove
~200 mile range on tank of gas
Dual headlights, but really, just make them bright and I don't care if it has 1 or 10.
Heated grips & seat (plus)
LED tail lights
Weight: low 500 pounds or high 400 pounds without fuel
Some exclusivity (not everyone owns one is a plus/exotic)
There you go. Make it and they will come...
