I'll let you guys choose.
#1) Royal Enfield flat olive drab (Always wanted one)
#2) Yamaha bolt R-Spec (I have one, it looks cool, just don't know how good this bike will look in that scheme)
#3) Satin black with red pin stripes (Tried and true, but not different)
#4) Other (Write in what you think would look cool)
