32 TEST: KTM 450SX-F FACTORY EDITION
KTM works the system and releases a limited number of special bikes to the
public in order to legalize their factory racers. The new Factory Edition was
built for Dungey, but will be the forerunner of 2016.
38 SHOOTOUT: KTM 250XC-F VS. YAMAHA YZ250FX
Yamaha has officially challenged KTM’s status as the bike to have for off-road
racing. The new YZ250FX is clearly designed to take on the KTM XC-F in the
250 class. We get front-row seats for the battle.

104 BOYESEN SUPERCOOLER
When it comes to efficiency, horsepower and thermal conductivity, what you
don’t know might slow you down. We go to Boyesen to learn the dark art of
cooling motorcycle engines.
108 CORNERING WITH ROBBY BELL
Robby Bell is one of the smoothest riders in the off-road world. We took a
good, long look at how he sets up for turns at the Taft WORCS opener, where
he ran away from the field.
110 LOGS WITH CODY WEBB
Okay, we don’t expect you to do amazing tricks like Cody Webb unless you’re
another freak of nature. But, he can teach you basics that will help riders of
