ultrarnr, here are the questions he posed on facebook:
"Hey guys, I need everyone's input. Craig Vetter is considering building a fairing kit especially for Zero's. It would easily bolt on and off in 10 minutes total using existing mounting points. Front and rear separate. What factors are most important to you?
1) range vs size. A bigger fairing could almost double highway range. A smaller one might add 30%. Or something in between.
2) cost vs complexity. What cost would be acceptable if it almost doubled range? Keep in mind a Powertank which increases range 25% costs $2500. If it was simpler it would increase range less, but cost less.
3) shape and design vs range. What do you want it to look like. The more like the picture here the closer to doubling range you get. The less extreme, the less potential gain you get.
4) size vs storage? The smaller it is the less storage space. How much weatherproof lockable storage do you want? 2 full face helmets and a decent sized gym bag?
5) passengers or a backpack vs ultimate range. Is ultimate efficiency most important or the ability to carry a passenger?
6) riding position? Do you want it to be most efficient (go 200 miles at freeway speeds in a tuck, but less efficient riding upright) or be most efficient riding upright (go 140 miles max highway, but can't get any increase in an emergency when you really need it).
Thanks for your input. Any other ideas on styling, preference would be appreciated.
- Terry"
The two working examples we have to go off are Terry's original faring and the faring Vetter made for Arthur Kowitz for his Brammo Empulse.
