Switching to a 520-size chain and sprocket combo can get you major weight savings, even on a 600. The RK 520 Race Conversion kit (available through FTM Enterprises; 760/732-3161, www.ftmbiz.com) is over a pound lighter than the stock GSX-R600 setup. The Vortex aluminum sprocket included with the kit (on the right) weighs a pound less than the stock Suzuki sprocket, a huge gain in unsprung weight.
