I bought this for my 2007 Kawasaki Ninja 650R. It is only listed for the 2006, but I checked the OEM part numbers and they were the same so I bought it anyways. I am VERY glad that I did; it is an excellent addition to my bike. I bought the black base with the chrome cap and it is very light compared to the OEM locking cap, plus I don't need the key to fill up. It definitely adds some bling, but looks great, not goofy.
