Specifically if you have an exposed black plastic fuel tank on a bike have you ever regretted it? Doesn't apply to a tank that's mostly covered by bodywork although most thumpers have some of the tank covered by seat and maybe radiator shrouds. Interested in any discussion about any colors for plastic fuel tanks, particularly fuel temperature and tank deformation. I'm looking for more riding range from the DRZ and prefer black, but willing to switch color if black is a really bad idea. Not interested in Rotopax or bladders. Thanks in advance.
