Most of the guys here will never ride on pavement much. Most of the USA wont allow it. Stock tires are pretty soft and wont last long on roads. I have seen most people in other countries either set it up for on road or off road. You may have to choose unless you like buying new tires. When looking at used bikes, just look how well they were taken care of. Some people just beat them and put them away. The cleaner they are the better the bike you will be buying. Look under it. Look for damage to frame and A arms. That will tell you how much it was used. Check the rear end for a broken subframe from flipping backwards. Check the coolant to make sure there is no oil in it. Check the oil for coolant. If all checks out its probably a good bike.
