Looking at snowchecking a 2011 Assault. Beat my knees against the chasis of my 2009 Assault. Has the chasis been changed to reduce this problem - hard to tell from photos.
I also sat on the new Pro rmk but found knees hitting panels. Thinking bars are to far forward or stearing shaft needs to be shimmed somehow to tilt back and then your knees would be further away from panel. Can't tilt bars back cause it feels funny when you turn them. Might try to get custom degree shims built when i get sled, also might need a bar riser after tilting it back.
