yeah the 48 with stock seat is living life on the edge haha. i always feel likeim going to fly right off the back with the normal seat. i swapped to the seat off the 1200c and its much better at highway speeds.
you didnt make a bad choice, you made the best choice
It's normal for the 48. Forward controls don't help. I hook my feet behind the brake and shift lever to help relieve my arms.
