The Energon Pub

That's my grandfather and his motorcycle.

I am on a mission to track down a bike just like that one, but the problem is, that's the only picture I can find of the bike at the moment and I can't distinguish what type of bike it really is.

Any ideas?

It looks like it's either a pan head or a knuckle head. I can't really tell because of the picture quality. Go to a Harley dealer, they'll be able to tell you.
