To all swinger tall with big a**.
i have removed the backrest.shift the metal frame at the backrest bolt up ,then put back the back rest.this will enable the backrest shift further back and up.it gives more leg room and shift the rider weight back.
Give more support fort the big a**,more leg room, more back support and less weight on the front fork.
I think it improves greatly and should have done it long itme ago!
