I have throughly considered shortening the bike and making the cockpit wider. I do appreciate the suggestions but I reserve the right to respectfully disagree. The great benefit of a CAD model is you can package everything before you make it. the fire bottle is behind the driver, you can't see it because the fuel tank is in front, but it's there. I also have the intake, turbocharger, exhaust, and coolant tank modeled but not in that picture. I want it short for transportation, storage, and yes, drag area.
Feel free to say I told you so if that day comes.
I will likely lengthen the rear behind the tire when I add the chutes and frame to hold them, but the basic structure will stay the same. The body is in rough draft form, so it will likely get longer, and I will add skirts for the wheels. probably I will also have the nose stick out farther forward so the air doesn't immidiately hit the tire.
How do you all feel about having the engine air inlet at the tip of the nose, in the stagnant high pressure area? not necessarily for power, but to reduce drag.
the rear tapers upward behind the rear tire to give some downforce. i havn't done the CFD to see if/how much, but I'll let you know.
