I just purchased my first ski a 2012 Yamaha VXR. Awesome SKi fast and fun to ride alone. My problem is when my son is riding with me he says the seat feels not safe. like he can not get a good grip and its like he is constantly sliding off the back. I did talk to our local upholstery guy to reshape and recover seat would cost $600. I was woundering if the VX Crusier seat and VXR seat or interchangable. HELP PLEASE.
