Hi all! Just got a new 2016 Sportsman 850 SP two seater!

Two questions:

1) When removing the seat to ride alone, does Polaris has a "filler" or something to replace the seat that is made for the machine? I’ve read earlier models have this, but I cannot find anything….

2) I’m a little worried about inclines with a passenger – can anyone offer any suggestions or experience on this? Last thing I want to do is tip backwards on my girlfriend. I realize much of this is "feel" and experience, but just looking for any advice.

Thanks!
