I am considering buying a 2009 700 xx. I have a kfx 700 right now and have owned several brute forces before that. I rode an XX today (first time i ever rode one), it felt pretty fast "all stock except for sway bar and kutter rear tires". I don't know much about these bikes. It felt very high geared to me. How much does the EHS big 3 help? Any other suggestions or comments? Thanks!
