I had the same problem with my daughter. Then I relized u can move the front seat forward on the mounting bracket and she fits her legs in with no problems. U should try it out. Still leaves enough leg room. My wife is 5'10" and fits fine.I have a PRP Booster Seat and my Son now 3 Can barley get his legs between it and the seat infront in the RZR4. I am thinking about a twisted stitch bench for the back thinking it might be better than the bucket seats for him. wonder if they could put in some lower seatbelt points for a toddler in the seat.
