This one gets my vote..
1975 HONDA MT 125 "Elsinore" aka "Elsi - snore"
Honda's early attempt a two stroke street/trail
This was my first full sized motorcycle in high school.
The bike was so underpowered it could not get out of its own way.
Handled good and had nice QD lighting. I still managed to have fun with it but always wished it had about 10 more HP.
