KTM is releasing an updated limited edition version of its 450 SX-F, developed from Ryan Dungey‘s 2012 AMA Motocross championship-winning race bike and KTM‘s R&D departments in both the U.S. and Austria.
The 2013 KTM 450 SX-F Factory Edition receives a number of updates from the limited edition model released last year, developed during Dungey’s Supercross and Motocross campaign. The 2013 version has a new electric start system and as such, the engine case and clutch covers have been redesigned to remove the kick starter boss, shaving about a pound off the bike’s weight. KTM also added a map adjustment switch and an hour meter to track the time between maintenance intervals.
The Factory Edition version features a number of upgrades over the regular 450 SX-F including a new seat, an Akrapovic titanium exhaust, orange powder-coated frame, matching orange triple clamps, rear sprocket, radiator and fork protectors, a front brake disc guard, gold racing chain, black EXCEL wheels, Dunlop GEOMAX MX51 tires, and Red Bull KTM Factory Team graphics.
Like the base model, the Factory Edition is powered by a 450cc single cylinder engine. Both versions are equipped with WP upside-down forks offering 300mm of travel but the Factory Edition’s WP rear suspension offers 330mm of travel compared to the regular model’s 317 mm of travel. The base model does weigh two pounds lighter than the Factory Edition however, which has a claimed weight – without fuel – of 236 pounds.
KTM will 710 units of the 450 SX-F Factory Edition – 555 for the U.S. and 155 for Europe.
