Bought my 15 new and have enjoyed it since.

You get the Honda reliability and a great ride with lots of power.

There are a few things I would like to have from the full wing...reverse is probably the top. Its not really necessary, but there have been more than a few times it would have been nice..

A few of the other little creature comforts wouldn't be bad either, but since 99% of my riding is just me, the other stuff isn't as important.

I would stay 15 and newer just because of the cruise control. I have a hard time riding anything without now...especially more than just around town.
