Anybody have any dealings with this company? My nephew is having issues with them and his Predator. 03, the frame is cracked (told him he's screwed there), motor knocking (in for second fix) and the rear shock is blown. Motion Pro in north Dallas has had the bike for 2 months now and gave an estimate of 4300 to fix it. They will warranty the rear shock. Curious if it's the shop, the warranty company or both.
