Has any one re-covered a ty250 seat. I need to know if the foam has a base inside the vinyl cover to to support it. The factory parts drawing shows the padded piece as a stand alone part that bolts to the fibreglass seat fairing. Mine is not original and it feels like someone has used a piece of plywood inside.

Dear zotz

The 1974 TY250(A) has a seat with unusual construction. There is a moulded foam piece which usually goes so hard it feels like wood as you describe. There is a pressed steel base in there which by now is usually mostly iron oxide. The cover is stuck to the foam piece and hence inseperable. The seat is screwed to that wonderful fibreglass seat surround that gives the bike a very distinctive look.

With a bit of persistence you should be able to buy a fibreglass replica seat base to suit the A model and take it from there yourself or take it to an automotive upholsterer with a good picture of what it looked like in 1974 to go by.

Yamaha made some replacement seats for the TY250A and TY250B with plastic bases. I know only because there was one on a bike I bought with the part number sticker attached. I don't think they are available any more from Yamaha.

There are complete new seats available for the C and D model TY250 but you will need a new, longer (C, D model) rear mudguard and some small mounting brackets added to your A model frame to make it fit.

Thanks very much for the reply. It's the steel base inside that I was curious about and now that I know I can go about making one.
