Framers, framers, framers. Framers rule. Not sure what one is? It's a flat track race bike with a specially built chassis made just for turning left and going fast. Not a road bike frame. Not a motocross frame. The purest distillation of flat track and Sideburn 42 is absolutely crammed with them. We have: Greenfield George's super-lightweight Survivor KTM 250 cover bike + Leftie's Sudo Cycles Co-Built Rotax + Scott Brelsford's Champion Kawasaki H2R 750 + Russia's only Trackmaster Triumph T120R
