I've been thinking about an offoad rig for awhile and now my failing body has me thinking about it even more. COuple of questions about the physical demands of riding hacks offroad. I've battered the hell out of my knees crashign streetbikes and just riding dirtbikes. Can you ride a hack offroad from the saddle, or does it invlove a lot of standing and peg weighting? I love the concept of the ural, especially the ability to drive the second wheel. Is this the best setup for offroading? I'd love to find something with more oomph after riding a KTM 950 th e last year. So, any thoughts on whether a hack would be less hard on my gimped body than a d/s or adventure bike?
