WHY UPGRADE?

Power steering offers several advantages for snowmobile riders, especially in challenging snowy conditions:

• Improved Maneuverability: Power steering makes it easier to turn the snowmobile, particularly at low speeds or in tight spaces. This is especially helpful when navigating through trees, around obstacles, or in confined areas.

• Reduced Rider Fatigue: The physical effort required to turn a snowmobile without power steering can be tiring, especially during long rides or in demanding conditions. Power steering reduces this strain, allowing riders to enjoy their experience for longer periods.

• Enhanced Control: Power steering provides more precise control over the snowmobile’s direction, making it easier to maintain a stable course, especially in uneven terrain or high winds.

• Increased Safety: By reducing rider fatigue and improving control, power steering can contribute to increased safety on the trail. It can help prevent accidents caused by loss of control or excessive strain on the rider.
