As the aftermarket still has some catching up to do, I would suggest taking some measurements with your vernier caliper and then going to a mega dealer and finding a mainstream bike that closely matches those dimensions. Pin diameter (8mm). Width of peg bracket channel and width of the peg portion that slides into that channel. Finally, distance from center of pin to rear of channel where peg bears when open. I would be very surprised if you didn't find an application that will work with your bike. In addition, you could call and speak with James at Slingshot Racing out in California and give him those dimensions and see if he has an application that will work. He may ask you to send a photo of the OEM passenger peg. He sells adjustable rider and passenger pegs for many different Motorcycle models.
I won't be a forum Dick and suggest you find a girlfriend with shorter legs. That would be rude.
