Super cool home-built race bike. Engine looks to be about a 1913. The fork looks stock but, the springer portion has been removed. Moving the wheel back like that must make for some pretty quick steering. The rear of the frame has been shortened and what looks like a bicycle seat added. Custom handle bars?
Just got back from a trip in the mitten. Met a great guy that showed me some of his amazing collection. He asked that I not divulge his name or location. Which I can totally understand. With that said I had a great time talking about motorcycles and bicycles with him. Not a Harley in the bunch!
