Hey guys dumb question - I was out on a ride with a friend on our street motorcycles today, and he tells me he's looking at getting a 250 2-stroke dirt bike for summer riding and throwing a track and ski on in the winter. I've never seen a 250 out on the hill before running a ts kit and told him he'd need a 450 or bigger - am I correct to say that? I don't think the 250 has enough juice to get going but I don't know everything.
