VTwin Mama (for sassy, classy women motorcyclists) has kindly put together a page of bikes suitable for shorter riders. The basics are these points:
1) Lower the bike with a lowering kit (new brackets that lower it or back end suspension/shocks and front end fork).
2) Change the stock seat to something that is either narrower (so the legs are not pushed out) or curved down to lower overall seat height or have the original seat’s interior padding shaved down.
3) Change out the tire (but talk to the mechanic about a possible impact on the speedometer reading).
4) Buy or modify boots for a higher heel (but not to high to interfere with foot controls).

There are adjustable lowering brackets for sportsters at vortexwaco.com, but I bought them on eBay. My husband installed them and they work great.
Fantastic! Sounds like you are having fun!
