STOP RIDING IT LIKE A DIRT BIKE

The Technique

1. Start with what actually changed. The rear wheel is gone and in its place is a track with a long footprint that spreads your weight over a large area and delivers thrust along its whole length rather than at one point. The front wheel is gone and in its place is a ski with a keel and a carbide bar. Neither part behaves like the thing it replaced. A tyre converts throttle into forward drive at a small contact patch, and when it runs out of grip it spins. A track converts throttle into forward drive, lift and float all at once, and when it runs out of grip it does not spin harmlessly, it excavates. On a snowbike the throttle is a suspension input and a flotation input as much as it is a drive input. That single sentence is most of what separates a good moto rider having a frustrating first season from a rider who is actually progressing.
2. The ski steers by pressure, not by bite. A front tyre turns the bike because it is narrow enough to cut into the surface and hold a line almost regardless of how much weight is on it. A ski is wide, long and designed to plane. It will only change your direction when it is loaded hard enough to set the keel into the snow. Unloaded, you can turn the bars to full lock and the machine will carry straight on, plough a wall of snow ahead of the ski and then wash out. This is the origin of the most common complaint from new snowbike riders, which is that the machine "does not want to turn". It turns perfectly well. It is not being asked properly. Steering input on a snowbike is weight first and bars second, in that order, every time.
3. Now name the moto instincts that hurt you. The attack position, weight forward and hanging off the bars, is the first. On dirt that loads the front tyre and buys you grip. On snow it drives the ski tip down and under, where the ski submarines, loses its plane and either stops the machine dead or knifes and throws you over the front. You still want ski pressure, but you want it applied vertically through the chassis from your feet and hips, not levered through the bars by your upper body. The second instinct is the rear brake. On a moto the rear brake is a steering tool you use constantly. On a snowbike the track is the only thing holding you on top of the snow, and the moment you slow that track in deep snow the machine settles and sinks. You brake with the throttle and with terrain. The rear brake is for stopping on a firm surface and for holding the machine still, and very little else.
4. The third instinct is chopping the throttle mid corner. A moto rider closes the throttle to tighten a line and it works, because a loaded front tyre bites harder. Close the throttle mid corner on a snowbike and the track stops pushing, the machine settles into the snow, the ski loses the pressure it needs to hold the arc, and the turn falls apart underneath you. Through a turn the throttle wants to be steady or very gently increasing. If you need to tighten, you tighten with weight and roll, not with the throttle. Learning to hold a constant throttle while your instincts scream at you to close it is one of the harder unlearnings, and it is worth doing deliberately on easy terrain until it stops feeling wrong.
5. Momentum is the currency and you spend it carefully. On a dirt bike you can stop anywhere, dab a foot, and ride away. In deep snow a stop on a slope can cost you a long stretch of digging, and it costs your riding partners the same time standing around waiting. Elite riders are not the ones with the best saves. They are the ones who set up lines that do not require saves, who choose an entry that flows into an exit, and who know at the bottom of a section how they intend to leave it. Before you commit to anything, know where the machine is going to end up and whether you can get out of there under power.
6. The body position that works is a neutral standing stance with real authority in it. Feet on the pegs with weight through the balls of your feet, knees bent enough to absorb, hips over the seat rather than behind it, back straight, elbows out and away from your body, and arms long enough that the machine can roll underneath you without dragging your torso with it. Grip the bike lightly with your legs. A moto rider clamps the tank hard and locks himself to the chassis. On a snowbike that lock is exactly what you do not want, because the machine needs to move independently of your body. Seated riding is more useful on a snowbike than on a sled, particularly on flat traverses and long transits, but you cannot roll the machine properly while seated, so anything technical happens on your feet.
7. Here is the mental reframe, and it is the whole lesson in one idea. On a dirt bike you and the machine lean together as one object. On a snowbike you stay relatively upright and quiet over the direction of travel, and you let the machine roll onto its edge underneath you. Your body is the stable reference and the bike is the part that moves. Riders coming from sleds understand this immediately because it is how a sled is ridden. Riders coming from moto find it deeply counterintuitive for weeks. Once it clicks, sidehills, carves and pivots all start working, because every one of them depends on the machine being free to roll under a rider who is not welded to it.
8. Finally, change what you are reading. On dirt, traction is largely visible and largely constant through the day. In the backcountry, traction changes with aspect, with the hour, with wind history and with sun. The same slope that carried you at nine in the morning can be a different machine entirely at two in the afternoon. Get in the habit of noting how the snow feels under the track at the start of every section, and of adjusting your expectations rather than assuming the machine has gone off. Reading snow is a skill you build over seasons, and it is the skill that makes line choice possible.

Common Mistakes

Hanging off the bars to make the machine turn. Fix: put your hands on the bars lightly enough that you could lift a finger at any moment, and generate all ski pressure through your feet and hips.

• Using the rear brake to control speed in deep snow. Fix: cover it but do not use it. Close the throttle and use terrain, and reserve the brake for firm surfaces and holding the machine at a stop.
• Riding stiff-armed and clamped to the chassis. Fix: soften the knees, widen the elbows, and consciously let the bike roll away from you on flat ground until the movement stops feeling like a mistake.
• Closing the throttle the instant a turn feels wrong. Fix: hold the throttle steady and fix the turn with weight. If the turn is genuinely unrecoverable, aim it downhill rather than shutting off mid arc.

The Drill

Find a wide, low-angle open slope with no trees, no rocks and a clean run-out. Ride linked figure-eights on a course about thirty metres across for ten consecutive laps. The standard is ten laps with no touch of the rear brake, no full throttle closure, no stall and no washout, with your hands loose enough that you can lift the index finger of your outside hand off the bar at the apex of every turn. If you cannot lift that finger, you are steering with your arms.
