Bought a new seat for my SS50 off ebay.
The old one made the whole bike look very dark and chunky, with a fully black seat with black piping.
This one has a nice "chrome" edge and its a little thinner then the old one.
It is aftermarket, but you just won't find originals.
And this one fits, unlike the aftermarket stuff sold in the Netherlands or the expensive benly seats that also won't fit with a CD50 tank.
Note the breather, just like his RSC90 big brother.
