Just get stock plastics. They don't cost much more, and are better made in every way. Maiers will crack, crease, and generally bust into pieces and look like trash much quicker than the stock ones. You can bend the stock ones to a 90 degree angle and they spring back, and at the most you'll just have a white stress mark which is easy to fix. The maiers also seem to fade out a lot quicker, and over time they start sagging, especially the rear ones. I've also seen other quality issues with maier, like the mounts not lining up without drilling out the holes, and the plastics coming orange-peeled from the factory.
As many different color combinations as there were from the factory there aren't many colors that aren't available from yamaha.
