As long as you are going to pretend your bike is a bobber you might as well use some back in the day hot rod parts.
They do have some cool lights but why do you say he is pretending? Can a cb not be a bobber?
it can be if you don't really know what a "bobber" is. Traditionally a bobber was what would now be called a "street/strip" bike. Basically it was your everyday rider that doubled as yoru race bike (or an ex race bike put back on the street). They are called bobbers because if you ever saw the gigantic fenders HD, Indian, Triumph, etc put on their bikes you would realize that they needed to be cut to be raced on the flat tracks (dirt tracks) that were becoming widespread in america at that time (usually travelling with country fairs or stock car races). On harleys it was a simple as removing a hinge pin and removing the rear section of the fender. The act of cutting the fender short was called bobbing (like the haircut from the 30s) and the bikes themselves were originally called bobtails and then eventually bobbers. Right around the 1960s having your streetbike double as your race bike phased out as factories got more involved and competition heated up (and the cost of racing took the sport out of the league of the poor). So unless your bike is a street/race bike built before the end of the 1960s I don't really see how it can be a true bobber.
What people call bobbers today are actually early style choppers. Before the long bike craze in the late 1960s/early 1970s, guys would build their streetbikes into chopped down bikes for the sake of style and performance. A lot of these bikes took cues and ideas from race bikes of the era including flat track and drag race bikes (the same source as the bobbers) but were not actually competition bikes. In the 1970s, hardcore choppers like the kinds 1%'ers rode were not the big iconic long bikes but were more like these early choppers - stripped down, jockey shift, lowered, springers, etc...
the problem is you get a bunch of ignorant guys looking at old "nostalgic" looking photos of old race bikes and early choppers and seeing no real difference between a street bike that actually doubles as a race bike and a streetbike that just looks like it does you end up with people calling early style choppers "bobbers". Additionally there are people who are so hung up with labels that they don't want their bikes called choppers because that term has become linked with the exagerrated long bikes and the jessie james style high dollar customs that they want to differentiate themselves - so they misappropriate the term.
Personally you can build a really nice early style hardcore chop out of a cb650, but unless you pan on actually cutting that rear fender and taking the thing flat track racing on sundays and then riding to work on mondays, I don't see how you can call it a bobber.....no matter what "the horse", "ironhorse", "hot bike", or any other style maven tells ya....
