My younger brother is learning on my TW and is looking for a first bike to purchase. I of course am doing the right thing and to steer him towards a dual sport for obvious reasons. He has interest in a cruiser but I can't have fun on the trails with one of those. Anyways he is 6ft 6in and about 220lbs. He will need to be able to ride on interstates for a few miles here and there. He needs a tall bike and he has a small budget of $1750. I'm thinking a XT 350 or DR350, the newer liquid 250 bikes would work but the price won't. Anybody have any input on a bike for a tall beginner?
