If you need to drive on pavement, asphalt, or concrete for short distances, stay in 2x4 and drive with caution: it’s an “off-road” vehicle, not an on-road vehicle and is not designed for asphalt or road use.
Treat every hill with caution, and travel up or down in the straightest line possible. Why? Driving at an angle, or sidehilling, shifts the vehicle’s weight to exactly where you don’t want it, and can lead to a rollover.
Before entering any mud hole, inspect both the terrain and your machine. How deep? For both regular models and X mr models, try to keep your tires visible at all times. (Keep that radiator clean, too!)
Yes, you can totally take your Can-Am Off-Road vehicle out in the winter. There’s going to be less grip when accelerating, turning, and stopping. We apply the brakes more often in the winter to keep temperatures up and reduce snow / ice buildup.
You’re a beginner, right? If so–find yourself an experienced spotter or off-road club, and take things slowly.
