I live in Texas and I have an after-market undertail. I put the sticker on the back side of the license plate. The law states that the inspection sticker must be visable on the bike.
Some dealers will put the inspection sticker on the back of the plate, other want to put it on a license plate holder. The last time I had the bike inspected, I had to put it on the holder. When I came home I just trimmed the holder and turned it around so it would fit on the back side of the plate. Some guys will trim the holder and leave the inspection sticker under the hump.
If I get pulled over I'll just tell the cop to
bend over...
