JUST ANNOUNCED: 2015 KTM 250 SX-F and 450 SX-F Factory Edition A 250 joins KTM’s Factory Edition fleet, which is significantly improved for 2015.

KTM just took the wraps off two new Factory Edition race motorcycles for 2015. While the KTM 450 SX-F is now entering its fourth year, it, along with the new 250 SX-F (which is making its debut for 2015), represents what KTM is calling “a whole new generation SX model motorcycle.”

What does this mean? Well, KTM says both of these 2015 motocrossers have been developed with weight reduction in mind, and improved mass centralization is designed to help on-track performance. Both engines are designed to be lighter, more compact, and powerful, with cases reshaped for the more centralized rotating mass of the crankshaft and clutch. This, says KTM, helps reduces the overall length of both powerplants.

In addition to re-worked Keihin engine management with a 44mm throttle body, both engines have new cylinder heads with revised valve trains. The combustion chambers are new, as are the ports, which are shaped for better performance. What’s more, both of the new Factory Edition KTMs have electronic launch control and five-speed transmissions said to provide “precise and easy” shifting.

As for the SX-F chassis, it too has been substantially reworked. The chrome-moly frame is lighter, and KTM says it provides improved handling thanks in part to better energy absorption. The subframe and swingarm are lighter, too, while the motocross suspension—with a WP 4CS fork and new WP shock—has damping tuned specifically for the lighter chassis. KTM, of note, says the 250 SX-F is 7 lb. lighter than a standard 250 SX, while the 450 SX-F is a substantial 10 lb. lighter than before.

As you’d expect, KTM’s Factory Edition models are very well equipped. In addition to limited-edition Red Bull KTM graphics, these new bikes wear a Selle Dalla Valle Factory Race Team seat, orange-anodized rubber mounted triple clamps, lightweight Galfer Wave rotors, CNC-machined hubs, and high-end Excel rims fitted with Dunlop Geomax MX32 tires. There is also a fork-mounted start device, plus an engine-map select switch and an hour meter.

Pricing for the new 2015 KTM 250 SX-F Factory Edition starts at $9,299; 2015 KTM 450 SX-F Factory Edition comes in just a little higher, at $10,199.
