Our seat-of-the-pants dyno has the KTM as the most powerful engine in the class. It has decent bottom-end, the power comes on strong in the midrange, and it keeps building power in the top-end and over-rev. The 250 SX-F’s power is like the Husqvarna’s but more aggressive as it revs quicker through the rpm range than the FC 250. Because of the KTM’s incredible top-end and over-rev, you rarely need to shift it as it pulls each gear for a long time. It doesn’t have as much bottom-end as the Yamaha YZ250F, but if you get too low in the rpm, a quick stab of the excellent Brembo hydraulic clutch brings the engine right back into the meat of the powerband with very little recovery time. The powerplant is also pleasantly quiet with a minimal amount of engine-braking. The new Pankl transmission makes the KTM and Husqvarna the smoothest-shifting bikes in the class.
