The 690 SMC is a lightweight supermoto that KTM presented as the successor to the 660 SMC, using the 654 cc LC4 single with electronic fuel injection. Its tubular trellis frame, one-piece fuel tank and rear fender unit and WP suspension keep the weight low. The page includes a comparison with rival supermotos from Husqvarna, BMW, Yamaha and Aprilia.
