MoJeeper, I was having the exact same concerns when considering the Pioneer coming from a RZR-S. I had to decide if I wanted to invest another $2000 in a small back seat / roll bar for more passengers (very cramped and no leg room), or go with the slower but more reliable Honda with plenty of room for 4. I went with the Pioneer. Yes, I do miss the speed and Power of the RZR at times, but I have to say I'm happy with my decision to go with the Pioneer overall. The shorter wheel base 4 passenger machine is what sold me and continues to sell me on the Honda Pioneer. I suspect once the aftermarket kicks in for the Pioneer, there will be something that will allow for a little higher top end speed, but I also suspect it won't offer a lot more speed. There is always trade offs and you'll have to decide what you need most? For me it was need for more passengers, shorter wheel base and higher reliability - the Pioneer has served me well in these areas. What I'm really looking forward to is a Honda Sport model ( 2015 or 2016) that has more power and speed, while hopefully offering the same innovative 4 person seating in a short wheel base machine. In the interim, I'll continue to enjoy my Pioneer!
