not a motorized bike, but I thought maybe y'all would know, being as a motorized bike might need to take more stress. I put a cheapish Schwinn style springer on my latest stretch project, but it flexes side to side way too much. I'm adding a large disc (203mm) and it hits the fork leg when I turn to that side. the fender also rubs on both sides, depending on which way I turn. for now I switched to a monark style fork I had, but I really want the Schwinn style. can anyone recommend a good one? thanks.
