These 'standard' pillion pads measure 10-1/2" x 4-3/4".

Haifley Bros. are located in Phoenix, Arizona and make Bates inspired solo seats and pillion pads right there in their workshop. Made with top quality leather over firm foam. The p-pads are hand stitched onto 1/8" thick leather bases. Hand-made in the USA.

I have one of these standard sized p-pads on my '59 Panhead chopper, paired with a Haifley Bros. 2" thick black tuck and roll seat. Couldn't be happier with the quality and comfort!
