80 kz750 | subframe May 4, 2015 by Matt with No Comment Custom Swing ArmFabricationmono-shock conversionsubframeWelding Starting with the top hoop, I make my first bends. I make both sides simultaneously, and along the way I look for symmetry more times than I can count. I first assemble the top hoop off the frame. Then I weld it in as you see here. So far so good. Everything is lining up and looking straight. These are the slugs I made up to attach at the bottom of the frame. Made out of solid stock, they weren’t easy to bend, but I got them looking pretty good. I bent up the bottom supports, attaching them with the slugs I had made. Top view. Left side. I am more than happy with the way the bottom struts turned out. Looking good from all angles. Right side. Everything lined up amazingly!!! I filled in the under-tray, and finished off the back of the subframe. I was really stoked on the way the subframe turned out!!! The suspension turned out great! Now on to the wiring, and seat-pan.
