welcome to the site Julie. The america bars (older) are pretty wide, the speedmaster bars will likely work for you but then you have to go with a pull back riser, not sure howlong your arms are but even iwth the rivco risers i find it to still be a reach. I am 5 8 with shorter arms. You might want to look into a bar/riser cobo, make sure 1" bar and 3.5" riser spacing, there are some out there, Harley etc that make nice bars that will fit these bikes.
