A bolt-on solution from LeBeeF for the front mounting of OEM solo seats on basically all seat-post suited H-D frames. This ingenious device with hinge installs into your center frame tube which normally houses the seat post. It consists of a bushing and insert with attached hinge. The bushing has a thru-rod attached by which it is permanently tied down into the frame tube. The bushing insert is secured with a pin which makes removal of the seat a snap. Large OEM type seats require an adapter bracket for the seat springs. On smaller OEM type seats like the ELR Knuckle seat the coil springs can be directly attached to the seat pan. A perfect solution for mounting those big Bobber Seats if welding on an old stock frame is out of the question.
