Hi all. I got a new red rear subframe for my 2013 675R to replace the scratched one. The new one came without the four black plastic infill panels, so I had to swap them over from the old one. If you look at the back of the subframe you'll see three plastic pips sticking through, on each infill. These are flexible, but only just. Any abuse and they will snap. My method was... Its a cold day so immerse the whole subframe in hot water to soften the plastic. A hair dryer or hot air gun would do the same. Now pinch the open ends of each pip together with needle nose pliers, just enough to push the pip back through its hole. Don't squash them flat...they'll probably snap. Once the panel is off with pips intact, you can just push it into its new home. A 'snap' confirms its locked in place. Job done. Ten minutes and no breakages. Good luck!
