Just received and installed some square mirrors and a Honda rack on my '14 deluxe. First I'd like to say how impressed I was with the order, Takashi goes the extra mile to make sure the packing is really well done. The order took about 7 business days to get here.
Mirrors were an easy install and there is a big improvement, my last bike had square mirrors, so that was what I was used to, I'm able to glance at the bigger mirror and see what is going on around me easier than the round ones. I had to take my eyes off the road longer to focus on the stock mirrors. I also found the round mirrors to have a lot of distortion in the mirrors.
I like the Honda rear rack, looks good and high quality. The install would have been faster if I had not dropped the washers 2 times, but it was not too bad of an install.
