As stated above it is a GB500. This happens to be a 1990 model. There are no differences between the 89 and the 90model years. Single cylinder with a four valve head. This explains the twin pipes. I have been looking at wanting one since they first came out. I just like the way the bike looks. To me it looks very balanced. It was for sale about an hour from where I live. The couple who owned it bought 10 years ago for the wife to ride. Family life (twin boys) didn't leave much time to ride so up for sale it went. I promised a good home with other bikes to talk to and home it came. The NT that my wife rides is the only other Honda that we have, so now that there is another one hopefully it won't feel alone.
I was very lucky to find a clean example of the bike as parts are very very hard to find. I do find it a bit ironic that the two Hondas that we have were only offered for sale in the US for two years. Thanks for looking I just wanted to share what I think is a fine example of what Honda can do when they want to.
