First welcome to the site!
If you look in the suspension section you will find many threads on altering the suspension. In general for best handing and cheaper mods look at having a shoe shop add an inch or more to your boots to make you more sure footed, then you could have an upholstery shop (or seat company) reshape your seat to make it narrower and lower so you don't have to reach so far.
If you lower your suspension much more you will have ground clearance issues when cornering and you will bottom out the suspension with it's smaller travel.
If after trying the above then you may be interested in an adjustable air suspension that you can lower when in a parking lot and raise up with the on-board compressor when riding. It will cost around $1,000 or more though.
