Hey guys, looking at getting a ryker. Dealer only has 900 that a test drove around the lot. They can bring a 600 from another location for me if I want that one. I was set on the 600 until I told them I want the 2 person seat for a passenger and they said to go for the 900 engine if I'm going to be carrying another person. Is this something that should push me into getting the 900 instead? I'm having a hard time finding comparisons between the 2 for 2-person riding.
