that's one of the things we looked at and it looks like that's actually where she sits. I have my soft bags on there now and they don't effect her. she can move all the way back to lean back on the top box and not cause a problem. I do have her scoot forward on gravel tho, the bike handles better that way.
actually if you look at the tabs sticking down on the grab handles the Corbin seat adds some to the front of the rear seat.
When I die bury me upside down so the whole world can kiss my ass.
