its different, but similar. When I first hopped on it, I felt like a beginner on a dirt bike. It didn't take long though to get the hang of things. Works better with more throttle :) There is no turning really sharp and there is no foot brake. Hand brake stops it. My brothers bike has the Rekluse Clutch so that makes it a plus. I noticed my arms were a lot more sore than if I were on a regular dirt bike ride. For sure its more of a work out. I did tip it over a few times and the thing is harder to pick up. Probably due to the fact its heavier and footing isn't as good in snow. They drain all fluids after every ride to ensure no moisture/water got in.
If you're on a snowmobile there are places you just can't go. On a snowbike you can go just about anywhere your riding ability will take you. The downside is if they break down in the back-country.
