Hi. It seems that for oem, the rear brake pedal for the 95 kx125 and 250 will work for your 1996 kx250. The rear brake pedal for the 1996 kx125 will work also. Try ebay for these parts. As for aftermarket, I have no knowledge on what will work for this. If you go to oem-cycle.com, they have an excellent chart on interchangeable parts for the kx250.
