I am starting a new thread on this topic to save others from having to sift through other threads where these are discussed, some of which are quite dated, and other off-topic threads where they have come up in the discussion. This information is current as of May 7, 2020.
You CAN purchase FJR1300 rider footpeg lowering brackets from murphskits.com. They are not listed on the site however you can send an email to [email protected]
or call him at 270-322-8097. He is based in Kentucky and is in the Central time zone. Sounded like one **** of a nice guy over the phone. For $93USD you get the brackets and the bolts and nylocs needed to reattach the footpegs (the pins currently holding the footpegs are used to attach the brackets). I believe that shipping to the lower 48 is included but its $20USD to Canada, though my countrymen should also know that there is no duty nor was PST/GST (which would normally add $16.85CAD to the cost at an exchange rate of 1.39384) charged.
Murph told me that he only makes one version of the bracket, which he believes was originally for a Gen1 machine, and he has heard that some have complained that the brackets didnít fit their bikes. My research on this Forum uncovered riders with the following bikes who said that Murphís brackets fit their machines: 2005(version unknown), 2008AE, 2015A and 2016ES, and to this list I will add my 2020ES.
I measured the distance from the top of the footpeg to the floor of my garage before and after I installed the brackets (which took about 20 minutes, only because Iím slow) and I can tell you that the brackets lower the rider footpegs by approximately 32mm (1.25Ē). This is a significant drop and it will affect the lean angle capability of the bike however I believe youíd have to be riding fairly aggressively for this to become an issue.
I took a short (30km) test ride this evening because it was cold (1C) and I didnít feel like getting all my gear on, and I found it was fairly easy to scrape the pegs during a practice serpentine exercise that I do. I took a ride through a favourite S-bend which can normally be taken at very illegal speeds without scraping the pegs and I did drag the pegs lightly on both sides at those same highly illegal speeds (4 times!) though it was no big deal. If the reduced lean angle is a problem you could always remove the curb feelers and gain back a few degrees and donít worry, the pegs will still fold with the brackets installed.
I will have to adjust both the shift lever and the rear brake pedal (which I seldom use, other than for U-turns) somewhat but I wouldnít even consider adding an extension to either as they are not necessary. I did notice that the centre stand is more of an issue for my left heel when I attempt to get up onto the ball of my foot however given my left knee issues bending my leg enough to get up onto the ball of my foot is not a fun thing to do anyway. For reference, Iím 6í-2Ē, 220lbs and wear Levis 505 jeans in size W36 L34 and a size 48 (13US) boot.
I plan on taking a longer ride this weekend (200-300km) to see how/if the brackets help my comfort/discomfort. Iím betting that theyíll be a great relief, especially to my left leg (a sad story involving a motorcycle and a younger me).
Hope others find this information helpful. Cheers.
