The R&G Racing frame plugs or frame inserts can be fitted with or without the boot guards.
The plugs are made from High Density Polyethylene (HDPE), which should make them highly resistant to road debris, fluids, rubbing or pressure from the boots and also temperature swings.
The frame plugs fill various holes in the motorcycle frame; holes that may be used to locate assembly nuts or bolts or other fittings.
Admittedly, the left and right frame plug kits are not as purely protective as the boot guards, but they do serve a purpose in covering up what many consider to be unsightly holes, such as the swingarm spindles.
On the BMW S1000XR, the large diameter (~40 mm) spindles show off the shiny aluminum construct of the frame but they also attract a lot of grunge, which equates to the need to clean.
Each frame insert or frame plug fits into and over the openings, providing a good seal while adding a bit of bling to the area, aided by an oval R&G sticker that mounts in the centre of each plug, once the screws underneath are secured.
Like everything else I have found so far with R&G products, the Boot Guard kit for the S1000XR (P/N EZBG0104BL) is simple and easy to install.
The heavy-duty adhesive-backed boot guard sections are about 2 mm thick and have a distinctive texture that goes well with the finish on the frame.
The individual pieces are well formed and cleanly cut.
However, for the S1000XR, they are not exactly the same shape and size as depicted on the packaging or even on the R&G website. Each boot guard piece is a bit short for this bike, ending at about the same height as the foot pegs.
When they’re installed, the boot guards end just across from where my boots are located, so I anticipate that the welts of my size 46 adventure-style footwear may impact or catch on the lower edges of the boot guards and that’s something I’ll monitor.
Before installing the guards, a quick visual check should be made to identify the left and right boot sides.
Also, laying each of them out on the designated areas of the frame is a good exercise to undertake before preparing the surfaces and mounting the pieces.
For surface preparation, two chemical-based (IPA) cleaning pads are included in the kits, but my experience with this type of chemical on some metal and powder coated or painted surfaces has been less than positive.
So without doing a test cleaning, I used a lint-free cloth and a drop or two of Goo Gone to clean the surfaces, followed by soap and water and drying.
It never fails (rubbing alcohol can be used also).
It hasn’t warmed to 20 degrees C here yet, so as is normal practice when working with this type of material (and as recommended in the instructions), a minute or so with the heat gun set on low did the trick.
This helps to get the metal and the adhesive warmed and easier to work with.
Starting with the left boot guard, I sliced the backing material at the mid-point and peeled the top section and located the upper half around the pivot point opening.
Then I worked up and outwards to the edges to prevent any air bubbles or raised surfaces.
But the cover over the adhesive on the lower part would not peel away cleanly, coming off in thin strips, even though the piece was warm and pliable. Otherwise, the pieces are very easy to work with.
Just pay attention to the round cut-out at the top of each piece during installation.
It is easy to stretch and distort that area during mounting, which would then not provide the perfect circular area for one of the included R&G stickers that is the finishing touch.
Before moving to the right side, another 30 seconds with the heat gun on low and a couple of minutes exercising the fingers in applying even pressure over and then around the edges serves to assist the adhesive curing process.
Repeating the exercise for the right side and experiencing the peel issue again added a minute or so, but other than this, this piece ended up adhered without any other issues.
Issues to Note
R&G should extend the amount of material in the lower sections of the BMW S1000XR boot guard stick-ons so they are down below foot peg level to provide better protection to the frame.
And while my kit might be an exception, the adhesive seems a bit thin and it tends to self-destruct rather than stay in place.
