Does anyone recall what year Penton used aluminum seat pan? I bought a new seat at Penton Brothers Honda in the late 70s as a replacement for the broken fiberglass seat on my 74 Berkshire. It worked OK but didn't seem to fit exactly the same.
Carl,
Based on the bikes that come through my shop, my best guess the aluminum pans showed up in mid to late 75 and the ones I have seen had a larger raduis over the back fender area.
Thanks Kevin.
