I bought this set as a replacement to previous block off plates that fell off on the track after forgetting to tighten the screws all the way. This was much better than spending $70. After all its just a small piece and gets the job done for a much better price. You can still see CNC tooling marks on the finish but it doesn't really detract from the overall look.
PROS: Cheaper Than Alternative, Works as expected
CONS: Finish Is Not Perfect, Can See Tooling Marks
The product fits and worked for me quickly when I misplaced my other block off plates. Way to expensive for two plain CNC pieces of metal with four screws. For the price paid I would expect it to be branded or etched with "CBR" or "Honda" or something. I like plain and do not want branding so expected a cheaper price.
I purchased the block off plates with some bar end mirrors, however when i went to install the plates the mounting bolts were to close together. I guess the 2013 zx6r has different mounts for the mirrors. Not a huge problem. I am currently using the bar ends with the stock mirrors removed, i just don't have block off plates on. Bottom line, be prepared to return them if they don't fit your bike.
