I purchased on ebay a cover that was advertised as "13' Deluxe Scamp Cover" I've only had it through 2 summers and this will be my second winter. Its held up well and I don't have any wear on it so far. It was
sold by "elitemotoronline". They may not have the one currently for your size but if you send them a message I believe they may have it. Don't settle for the one that does not say "Deluxe". It is tempting because its cheaper, but others on the forum said it fell apart quickly. I and others haven't had any issues with the Deluxe and recommend it. It
sold then for $119.99 plus $20 shipping. Others on the forum advise against using these soft covers, but its worked well for me. If you have a nice finish on you Scamp be sure you put the cover on a clean Scamp. The dust and dirt will scratch the finish otherwise. Good luck.
