Harley

It's hard to tell from the pictures what the engine is but the heads appear to be stock H.D. There isnt any badgeing on them, like S&S, Rev-Tech, S/E ect.There's no way to tell whats inside. Could be a stock 80 incher or have a stroker kit in it.
The really neat thing about this bike is that it's a 4 speed. This bike started life as a Super Glide. I'm not saying that it's super rare but the factory did not make as many of these as they did softails.
Good luck with your sale. Spring is comming, it will go.
