For 2015, all four-stroke MXers—250 SX-F, 350 SX-F, and 450 SX-F—share a new frame with 26.5 degrees of steering-head angle and a 58.8-inch wheelbase. Powdercoated KTM orange, the frame retains its upper-backbone/lower-double-cradle structure in chrome-moly steel tubing.

For 2015, all four-stroke MXers—250 SX-F, 350 SX-F, and 450 SX-F—share a new frame with 26.5 degrees of steering-head angle and a 58.8-inch wheelbase. Powdercoated KTM orange, the frame retains its upper-backbone/lower-double-cradle structure in chrome-moly steel tubing. The inverted 48mm WP 4CS fork is new, as are lighter CNC-machined triple-clamps with 2mm less offset than those fitted to last year’s models. They provide a slight increase in trail, specifics for which have not been announced.
Rear suspension is completely revised and now features a lighter cast aluminum swingarm, an updated rising-rate linkage with a lighter-yet-stronger forged cross member, and a retuned WP shock. Wheels travel at the front is 11.8 inches and 12.4 in. at the rear. Front-wheel axle diameter has been reduced from 26 to 22mm. All three models are equipped with Brembo brake calipers with 260mm front and 220mm rear Galfer wave-style rotors.
