I've always liked the look of a finished undertail and hotbodies has their ZX14r undertail on sale. I ordered one back in June and when it came in it was the wrong green (the lime racing green - not the Blaze Green on my '17 ZX14r ABS SE). Contacted them and they had me send it back to them (they paid shipping) - took until this week to get it back. Turns out this paint is nearly impossible to match according to a custom painter I know. They tried several times and got it as close as they could. If you look at where the panels meet closely you'll see it's not quite the same but being under the tail in shadow it's not really noticeable most of the time.
I had to trim a little in a couple places (where it fits around the tail section frame), create holes for the mounts for my saddlebags, and open the push rivet holes a bit. Lastly, I made a couple holes in the bottom of the stock plastic for the nuts holding the brackets for the license place so that they weren't creating a gap below the brake light.
