The Piston Ported Low Profile seat. An extremely high quality seat with loads of style from the pleats and medium grey piping all the way to the waffle patterned sides.
A firm yet comfortable footprint that's great for 2 up or solo. Mounts directly to the frame with a cutaway for the fuel tank flap. You will not be able to run your air scoop with this seat but air flow is not restricted if you are running the air box.
A very nice seat that offers great looks and will compliment any S1-GP model Lambretta.
