Looks like it uses quite a bit of Felt components, there's a company Ridley Motorcycles that makes motorbikes out of Felt cruisers, look similar although that has a custom springer
The tank names builder but can't make out the name, J something M something Concepts. I'd like to know what that motor is, definitely not one of those cheap chinese turd boxes.
The motor, or at least the block is a whizzer. The head and cam cover look like they've been cast/machined and aren't factory items. It has a rather large aftermarket carburetor as well. Not a bad looking bike all together.
