My wife rode one of those for a couple years before she got her Ridley. ( we still own it ... big bore kit and stroker cam )
Since winter is upon us soon ... why don't you have the seat re sculpted to fit your butt print?
Almost any upholstery shop can do this for a reasonable fee.
I know there is lots of room above the seat pan to make this happen.
I would think that will be a safer option ....
