Babysitting a little CB

[Cormanus]

Cormanus, it is weird that the link to the CB500 Four has a photo of a Benelli bike.

Anyway, to quote someone else:

Both the 500 and the 550 each came with two different models:

500T: twin cylinder, basically a bored out 450 with less power (42hp)
500F: four cylinder, 48hp

550K: four cylinder, four exhaust pipes/mufflers, two per side (50hp)
550F: four cylinder, slightly different paint scheme from the 550k. Main difference is the 4 into one exhaust. All four exhaust pipes sweep to the right side of the bike and collect into one muffler. There are a few other subtle differences between the 550F and the 550K, but the exhaust is the main difference (50hp).

Here's a brief video of the CB500 Four:

I found that strange too. It also has a picture of a 1977 Suzuki GS550 before you get to the picture of the CB500.
