I am 6 Ft tall and the stock seat belts work great for me. Wife is shorter and the belt rubs her chest neck bad. On the old 800s you could lower the belt height on the post. Any one else have this issue and what are you doing? Only thing I can think of is buying one of those pads for the shoulder belt. I do NOT want to hear buy harnesses, I am not doing those on this machine I didn’t care for them on the old machine.
