So I have been checking out the no lock fuel caps. The ones for our Victorys are crazy expensive. So I have been looking around for one for my old 2011 XR. Did some measuring and finally ordered one from ebay for a Yamaha R1, R6,etc. . Got it the other day sure looks nice, twist to open it up. The bolt holes are correct, same spacing as our Victory XR/XC. Did not take long at all to swap it out- F----me over. I gambled & lost. It does not fit into the opening on our tanks correctly. So NOOOOO they do not bolt in. So I gambled and sent $22 roughly to China to feed a few hungry people, maybe. No I do not have a Yamaha R6, R1 or what ever. So maybe I will hang it on the wall, it is black and it is machined nicely, ha, ha. So save your $20+ and put it towards that $160 cap that fits(maybe).
