I grew up on quads and the occasional dirt bike in the Midwest, and now I'm thinking about picking up the sport again. I'm in my mid 30's, 6'3", and about 240lbs. Haven't been on a quad or bike in about 10 years. Have been considering a 250 4 stroke, but keep leaning towards a 350 (like the KTM XCF-W). I live in SoCal, so most riding would be desert, high desert, and trails. Regardless of which one i get, I will have months and months to work on handling the bike, getting used to riding. I Just feel that going with the 350, might help me to grow into the bike a little bit more, and I see it is something I can hold onto for years to come. Let me also say, but I will have a lot of learning to do. I'm used to mainly quads in the Midwest, and here I'll be on a bike in Southern California. This is not something I plan on just ripping right out of the box, but really taking my time to learn it. Given that I am closer to 40, but I am 230, and then I'm a kind of a toll and heavy dude, do you think that a 350 would be the way to go?
