I have noticed that the shifter on the 900 4 sits closer to my right leg while driving when compared to my 900 trail. When I looked closely the shifter rod in the 900 trail is actually tilted away from my right leg where as the 900 4 shifter rod is straight up and down. If it is possible I want to put a 900 trail shift rod in the 900 4. It would be more comfortable and provide a roomier space for the driver.
