the early 650 and 1100 classic bikes look nearly the same from a distance, they had the round air filter too.
the later 1100's look a little bit different. The 650s all look the same.
that is one thing I like about the Vstar bikes, they got things right from the beginning, and did not have to change anything.
Another Yamaha bike like this is the SR500 / 400. Yamaha has built that bike since the late 1970s, and you look at the first one and this years - its the same bike.
