This is an application specific item, so probably not many of you (if any) either can or would want to use it. Here's what it is:
It mounts around the gas cap on your tank and provides a mounting point for a camera, smartphone, GPS, mp3 player, whatever. I bought this for my 1990 600R and it did not fit. The radius was too small. So, if this is something you think you might be able to use and you want to give it a try, just post a reply. The first person to say they want it will get it shipped to them for free. Tell me what kind of bike you have when you reply.
According to the description it fits the following Kawasaki models:
ZX 6R 636 (00-06) , ZX 10R (04-05) Zinja ZX/ ZX-R/ Z750/ ZZR/ ZX9R/ 7R/12R (93-99)
I can provide measurements if you want, but I believe it will fit only the models listed. If no one says they want it in a week or so I'll just move it on to eBay.
