This Genuine CoolAss size is what’s used / ordered most of the time. Fits nearly every Vespa, many Hondas, most Kymcos, Lambretta, Aprilia, Buddy, Stella and the like. Perfect for the Piaggio MP3 500, Yamaha Zumas, the Vino 125 and so many more.
Material measures about 30” x 21” when laid flat, with a drawn elastic perimeter of roughly 57”. If the measured distance around your combined saddles is between 62 and 102 inches, this is your Genuine CoolAss. Yeah, yeah, you can tuck in a little excess if need be. You’ll still be respected in the morning.
