What kind of modifications would be necessary for a trip of 5000 miles? I have a 2003 model with heated grips, clarke tank, and a two tooth less sprocket for trail riding. I understand a seat modification is a must, but what specifically? what model of windscreen? what model luggage and rack? any bags over the rear seat? type of tires? size of sprocket? anything else? I plan on going in spring with a friend and his DR 650. thanks in advance.
