450 EXC-F SIX DAYS (MY2018)

KTM built this one to celebrate its International Six Days Enduro record, and the hardware backs the graphics up: an anodized orange frame, CNC-machined triple clamps, a floating front disc with a solid rotor at the back, and a carbon end cap on the pipe. Underneath sits the 449 cc liquid-cooled single, 62 hp and 36 lb-ft, hung in a light steel frame with WP suspension and a 6-speed box. It reads as a limited run with the parts catalog already ticked, and it sits at the sharp end of the 450 enduro class rather than the friendly end.

Power delivery is the useful kind for dirt, tractable enough to pull through tight singletrack and long-legged enough for open desert. The chassis is what you notice over a full day. It goes where you look, and it shrugs off the sort of abuse that ends lesser bikes, which is why these hold their value with people who actually use them. The caveat is honest. At 37.8 in the seat is genuinely tall, the 2.3 gal tank sets the length of your day, and there is no ABS or traction control to cover a mistake. This is a race machine, and it expects race-machine maintenance.
