Kicker BS 540.

1. Approach the kicker dead straight with the base flat, no edge engaged.

   BS540 needs a touch more speed than a BS360, so don't scrub off speed near the lip. An angled, edged approach makes the spin tilt off-axis.

2. On the table just before the lip, pre-wind your upper body the opposite way of your spin (toward the frontside, toes side).

   Keep your hips facing forward and let only your shoulders and chest coil back first. Because BS540 is a half-rotation more than a BS360, load this wind-up deeper than for a 360, until your lead shoulder points well over your back foot. Send your eyes the same way.

3. At the lip, extend both knees to pop straight up and, in the same instant, swing your loaded lead shoulder around toward the backside.

   Match the pop and the shoulder swing to the same moment. The spin you generate is set almost entirely here, because you can't add any once you're in the air, so commit everything to this instant.

4. The moment the board leaves the snow, hug both arms in front of your chest and pull your knees up to make your body small.

   The tighter you tuck your arms and legs, the faster you spin for the same effort. Open arms slow the spin and you'll come up short of 540.

5. Lead the rotation with your head and eyes.

   You'll lose sight of the landing as you pass through the blind, backward-facing zone, but keep turning your chin toward the direction of spin and the landing slope will come back into view about a half-rotation early. If the eyes lag, the body lags and you under-rotate.

6. Once you spot the landing, open your arms out to shoulder height and let your knees extend slightly.

   Spreading your limbs brakes the spin and stops you from over-rotating.

7. BS540 lands switch.

   Land with your original back foot pointing downhill (forward), base flat, weight centered between both feet and stacked right over the board.

8. Absorb the impact by bending knees and ankles deeply while keeping your back tall so you don't collapse.

   It's easy to sit back in switch, so keep your sternum slightly toward the direction of travel to hold your fore-aft balance.
