I was sitting on the V4 today. I can't yet comment on the stiffness of the suspension but the riding position is perfect for my 5'8" frame. It's actually more comfortable around the knee area than my 959 which could benefit from rear-sets as the pegs are 1/2 inch too low for my legs.
Yeah I also came off the 959, the seat/tuck positions are much more comfortable. What I need to know is the info on the Showa/Sachs rates so I can give them to dave, nobody has that information though, I might reach out to DNA.
