anybody know where to buy the stock saddle upholstery...thanks in advance...

 

Stock saddle upholstery? Like in OEM? I dunno. Guts Racing has replacement seat covers but they look more like they are for racing (skinny) saddles. GUTS Racing

I made my own seat cover using black marine vinyl but that may not be what you are looking for.

 

I'll bet a guts cover will fit over the stock seat. I have the guts tall seat foam and tall cover. Very grippy and much better than stock imo.

 

You mean the genuine artificial fine Corinthian leather?

I bet most larger upholstery shops can get you something similar to the OEM stuff..........little tricky getting it installed.
I had an old 75 Kawasaki G5C-100 Enduro I had a shop do for me several years ago.....turned out sweet.

 

The Guts tall foam is a bit narrower than stock but the shape is nicer. Flatter, without the major dip in front of the tank.

 

I went with a seat cover and foam from Seat Concepts. It is a lot flatter for better support. I did save the old foam and cover if your looking for that.
