That fuse exists on the 500FFFFF (for clarification purposes so you do not think I am talking about the 500T).
You have quite a collection of fictional bikes. 500T is a twin and discussion of this belongs in other bikes.
US model CB500 was offered in 71, 72, and 73. They were K0, K1, and K2 respectively.
In 74, the CB550 (K0) was offered. The K model 550's continued thru 78.
In 1975 the CB550 F was introduced and the F model was offered up to 77.
Info source is a book published by American Honda motor co. called the Honda motorcycle identification guide.
I suspect that some have assumed that the CB500 Four side cover badge, with it's over sized F in Four, mistakenly call it an F model.
However, I have to assume that anyone thinking or saying they own a CB500F simply doesn't know what they are talking about, to put it bluntly.
Cheers,
Yay for you. Able to ejaculate quotidian information on a whim. Get over it. I love my CB500FFFF. I'm going to love it even more when I get the rebuilt swingarm back from Hondaman.
By the way, TT, check out this link. It is Merriam Webster's definition of "tact". http://www.merriam-webster.com/dictionary/tact
Perhaps you can study the definition of "tact" with as much zeal as you study your quotidian Honda model knowledge. Then, maybe you can reread my comment on why I put the "F" after CB500 and stop being so pedantic.
