2. Those performance<br />
gains didn’t come out of thin<br />
air—they are a product of<br />
being able to bring it in more<br />
efficiently, among other<br />
updates. If you want to create<br />
more power, you’ll need to draw<br />
in more air and fuel, then expel<br />
exhaust gasses more effectively,<br />
so that’s just what KTM did. To<br />
that end, a wholly revised air<br />
intake through the center of the<br />
headlight has been introduced,<br />
coupled with a redesigned<br />
airbox that creates a ram-air<br />
effect at high rpm. Also, top-feed<br />
fuel injectors and more powerful<br />
coils have allowed engineers<br />
finer control with fueling,<br />
creating much better response<br />
at the throttle. Meanwhile, larger<br />
54mm and 60mm headers<br />
increase The Beast’s ability to<br />
eject gasses, while also making<br />
use of a dual catalyst solution.<br />
The main catalytic converter<br />
is under the motor, and a<br />
secondary unit is in the new<br />
muffler to beat emissions.<br />
