Tree house I've had my 75s for over 20 years and over the years. As I have matured (gotten old and decrepit) I have progressively modified my bike to suit. The handle bars were first rotated up and back progressively, then a block was added moving them up and back. The seat was lowered and repadded, I still have an OEM seat unmodified. You might want to try playing with the bars before you get rid of it. As yet I am still using the 75s bars but there are alternatives. The windscreens can also be made shorter or longer.
Regards Martin.
