Well I saw this before but didn't see this exact key so I wanted to share with everyone. I think one of the complaints some of us have is the original factory key is way to big. I did some cross reference and searching around and found another key that would work with our slingshot. I saw some where someone was using a model "KW14" but the only problem was most of them didn't have a rubber or plastic on head.
I bought this on ebay and searched "KW14AP". It looks like it is used on Kawasaki, Ducati, and Victory motorcycles. Anyways I received mine today and its the exact blank of our key. I just went to my local ace hardware and had it cut and works flawlessly. I figure I share with anyone else who doesn't want a bulky key or just wants spare keys in case of anything.
