This is the fourth year that KTM has produced a Factory Edition model. It's a bit of marketing genius that allows them to created a limited edition bike for the public, but that also has the very latest spec for the Red Bull KTM team to ride, just ahead of the upcoming race season.

The 450 SX-F Factory Edition will retail for $10,199, and add-on benefits include: Red Bull KTM limited-edition graphics, Selle Dalla Valle Factory Race Team seat, orange-anodized rubber mounted triple clamps, lightweight Galfer Wave rotors, CNC-machined hubs, high-end Excel rims fitted with Dunlop GEOMAX MX32 tires, KTM/ODI lock-on grips, KTM PowerParts fork mounted start device, engine map select switch and a KTM PowerParts hour meter.

This is the first year for a 250 SX-F Factory Edition, which has a suggested retail price of $9,299, and it's similarly equipped to the 450, with a batch of extra goodies.

This is the bike that Red Bull KTM riders Justin Hill and Marvin Musquin will ride, along with the Troy Lee Designs / Lucas Oil / Red Bull / KTM squad of Jessy Nelson, Shane McElrath, and Darryn Durham.
