You may be able to make it work. If you take the stock fender off and lay out the screw holes then drill new holes, it *might* fit in that area. The signals look like they mount the same as the FZ6 so it might work out OK. At the most, you might have to also trim the plate where it meets the tail. From someone elses pics, it looks like the R has a recessed area that may not be sized to this FE Kit, but I think you can modify it to work with a bit of cutting, grinding and drilling.
If so, please document and take photos to benefit the others with the new R! :thumbup:
