I don't think you can compare riding a snowmobile and a dirt bike very well. It's comparing an orange to an apple. Yeah, they're both round, and both fruit, but imo they're quite different animals. I've ridden both for years and no matter how much snowmobiling I get in, that first ride down at the dunes on my CRF450 always leaves me so sore I can barely walk. The opposite is true also, I can ride all summer and fall, and that first ride on the sled kicks my butt just as bad. The cool thing about the bike is that conditions aren't as important as they are on a sled. You have a great time if it's dry and sunny or wet and overcast. I do like how there are jumps everywhere (especially at the dunes) on a bike where on a sled they are fewer and farther between. The rush I get on my bike is good, but doesn't compare to a sunny deep powder day on a sled. So it's more quantity than quality compared to a sled, but still really good. I too have gotten pretty banged up on a bike WAY more than on a sled, so good gear is a must like someone said. And of course, the bike is soooooooooo much cheaper to ride!
