I am interested in getting a dualsport dirtbike and am wondering what size engine would be a good starting point. I have no experience with motorcycles but I do have experience with snowmobiles and in that case a 330 felt like it did not have enough power and a 550 had pretty much the perfect amount. A bike I was looking at is only a 250 and I am wondering where that will fall in terms of power. I guess what I really want to know is, to get a bike with as much take off as the 550 snowmobile would I need around the same size bike? Thanks in advance.
