There should be more than 4" of clearance at the rear given the tail is only going to be about 2 or 3" under the frame of the body, maybe even flush with it idk yet.

It would really suck to drag a tail down hill. Let me do some quick math. Ok it would take a slope of 21 degrees to start dragging tail with the bike not bottomed out. If it was bottomed out it would take a slope of 9.3 degrees to touch down.

Bike bottoms out at 3" off the ground. My wheels are 17" rims so about 14.5" from axle + the 4" from loft.

EDIT: Just realized / remembered the seat cowl Vetter is building angles backward >_< This means the above is wrong as that isn't the final vertical profile. Oh well, getting faster at producing them so.
