I have been meaning to get these for ages. On the right side, especially, they really tidy up the bike in my opinion - hiding much of the exhaust, the O2 sensor, and various pipes. Available from Kawasaki as an accessory - about $50 for the pair here in Thailand. I'm sure it is now more Ninja streamlined and massively faster too! Okay, maybe not, but I like the look... They come in matt black, or black gloss - I went for the matt option, just because I thought it might not show the dirt as much as gloss.
