Please list the pros and cons of each bike. Right now my dad has a stock (he won't modify his bikes AT ALL) DRZ 400 S '03. He can never follow me(15 yr old son) when we go riding because his bike can't handle the stuff my Crf 250X goes on and he's in the mood for a new bike. He wants a bike that you can just lug up anything, has low maintainence, Lots of torque down low, and that feels stable. He wants the 400 but I told him to look at the 650 as well. The main concern with him is that extra weight. Cheers, please respond soon I need to show my dad this when he gets off work.
