It seems that buyers constantly seek "new" things. Even if that means just offering new colors. Looking at the basics of the bike, it's just a softie version of a Super Glide.

Like any other product from yachts to Dixie Cups, if you like it, then buy it. But buy it because it fits your personal needs. Not because it looks good in a brochure.
