if you step on the running board on the right side there is nothing to stop the bike from falling over.
If you cant swing your leg over because you got gear or a trunk on the back, seems like you should be able to push your knee over the tank and let your foot follow across the seat.
My bike is kinda stuffed in the garage right now, so I cant try that. With the trunk on my bike I just swing my boot over the trunk.
maybe it would help if you parked your bike by a step on the left side, or had a Rubbermaid foot stool there,
