Seller notes
Brand new replacement backbone for your 1940-1947 knucklehead or big twin flathead. Made from United States steel DOM .120” wall tubing. Dimpled on the bottom like the factory and machined at the end for the seat yoke casting. I also make the backbone for the earlier EL motors. I actually make every tube on a knucklehead frame. Everything is made from strong DOM tubing....
