When I picked up my new 2015 Sportsman 1000 XP Touring , you could not go over 25 mph without shaking you off the unit. After 4 sets of rims and 6 sets of tires,($900 out of my pocket for RipSaws) it turns out that it is the EPS unit had a bad connection. Dealer says that its good to at least 70 mph now.:add_twinkle:
