We picked up our 520 today and the dealer had a 500 next to a 520 The 500 was a little dirty and was in for a service and it had 25 inch tires. There are a few differences mainly the exhaust pipe and an addition of some front inner fender protection that I liked. the roll cage was just about the same with an added bar to the frame under the drivers seat. I have never rode in a 500 so can't comment on the shocks. They have the same design from the looks but the part number if different so I assume the valving may be slightly different.
