MOTOCROSS 350 SX-F A CLASS OF ITS OWN Nearly the power of a 450, combined with the agility of a 250 – by winning the MX1 World Championship 2012, Antonio “Tony” Cairoli has now proven the potential of the 350 SX-F for the third year running. In order to keep the advantage over 450 cc MX1 contenders, KTM improved the performance of the 350 SX-F once again. For 2013 new ports in the DOHC cylinder head provide better gas flow, stronger intake valve springs and a lighter piston allow higher rpm. The crank shaft is stiffer and lighter than before and wears a pressure lubricated plain bearing for the connecting rod. The engine cases are produced in high pressure die cast instead of sand cast which allows a massive weight reduction by thinner walls. As all MY 2013 four-stroke engines the 350 SX-F is equipped with a new Keihin engine management system and fuel injection which allows for higher gas flow and improved spray. Moreover the 350 SX-F is benefitting from a significantly revamped chassis with new triple clamp, reworked frame and swingarms, stronger rear wheel axle, and modified settings. The new suspension scores with even higher reserves against bottoming out, improved responsiveness, and even better tracking stability. - Reworked cylinder head, cylinder, crankshaft and piston for even better performance - New high pressure die cast engine cases for reduced weight - New state-of-the-art Keihin engine management with optimised fuel injection - Ultra-light chrome-molybdenum steel frame with reinforcement in the steering head area, newly designed head stays and with cradle tubes made of thinner profiles - Reinforced ultra-light aluminium swingarm, single-piece cast, with larger rear axle - Optimised linkage-type rear suspension with fully adjustable WP monoshock, harder spring and new set-up - Optimised, fully adjustable WP 48mm USD front forks with CNC machined triple clamps, closed cartridge technology and new set-up - New airbox with optimised flow rate - New bodywork with enhanced ergonomics MEDIA INFORMATION
