To install X-Head 1250 Cylinder Guards on an R1250 GSA, it is necessary to remove the lower crash bars to provide enough working room to position the Guard. When re-positioning the crash bar, carefully position the rubber pad riveted to the inside of the GSA crash bar in the space provided at the back edge of the X-Head. Keep the crash bars loose when re-inserting its mounting bolts, then tighten after a good bar position is set.
Prior to mounting X-Head 1250 over the cylinders, it is recommended that a coat of paste wax be applied to the contact surfaces of the cylinder head.
X-Head 1200_LC cylinder head guards for 2013~2018 R1200 models are again available. They now include stronger T-50 M6 bolts after a number of customers broke them during installation – usually because a torque wrench was not used or not properly used.
If you have experienced T-50 M6 long bolt breakage and do not have replacements, please send an email to email@example.com and provide your name, mailing address, and briefly describe your experience. Please write ‘T-50 bolt’ in the subject line.
According to information gained to date, MudSling_LC fits best with standard fitment tires like Metzler Tourance Next, Michelin Anakee, Bridgestone Battlax Adventure A41R, Pirelli Rallye STR, and Mitas E-07 – a 50/50 tire. It also fits a limited number of knobby tires, depending on whether mounted to a GS or GSA. This is due to differences in tire cross-section shapes and diameters. The GSA also has less clearance than the GS because of different suspension geometry and 20mm more suspension travel, so minor differences in tire shape will determine if the tire will rub the MudSling or not.
Knobbies that FIT with MudSling on the R1200/1250 GS and GSA: Michelin Anakee Wild, Continental TKC70, Continental TKC80, and Mitas E-07.
Knobbies that DO NOT FIT with MudSling on the R1200/1250 GSA: Continental TKC70, TKC80, Bridgestone Battlax Adventure AX41, and Hidenau K60 Scouts.
Some customers have reported that Hidenau K60 Scouts are a close fit on the standard GS, while others have reported rubbing the MudSling when the tire is new. Hidenau K60 Scouts DO NOT fit the GSA. Because Hidenau DO NOT fit consistently, we do not recommend using them with MudSling. Pirelli Scorpion Trail II are a close fit.
Michelin Anakee Wild knobbies Do Fit on ADV shown below.
Among all tires clearance with the MudSling while on the center stand is the least. Taken off the center stand, the bike’s weight compresses the suspension slightly increasing clearance with the MudSling. With a rider aboard and the suspension working, clearance increases even more. The more the suspension compresses, the more the clearance.
A possible solution for tight tire to MudSling clearance:
Apart from tire choice, we have also found considerable differences in assembly tolerances from
bike to bike which can affect the position of the large under-seat plastic molded liner. That large part is the MudSling’s primary locator.
Here is an example reported by two customers that proved assembly differences among bikes to be true:
Two friends each bought a MudSling GS_LC at the same time for their same year GS’s. The
MudSling fit perfectly on GS #1 with sufficient clearance. The MudSling on GS #2 made contact
with the swingarm. I asked the guys to swap MudSlings to determine if the variable was the
bike or the part. When they were swapped, the MudSling that fit properly on GS #1, did NOT fit
GS #2. Conversly, the MudSling that did not fit on GS #2, DID fit properly on GS #1.
To compensate for this possibility, there is a solution to try to gain 3~5mm between the tire and MudSling:
1. Remove the seat to reveal two tabs which support the inner fender liner secured to the top
of the frame rails.
2. Remove the two screws securing the tabs with a T25 Torx driver.
3. Find a 3~4 mm thick rubber washer 20mm in diameter, or cut it out of flat rubber stock.
Nylon washers may also be used. Insert the rubber shims under the plastic tabs and re-tighten the screws.
This work-around usually works, but is not guaranteed depending on your bike’s assembly tolerances.
The Avant 12GS_LC front fender extension fits the 2019+ R1250 GS Adventure with the standard BMW skid plate, but does not fit the optional Enduro skid plate on the GSA. The Enduro plate extends farther forward than the stock plate and, because of the steeper front fork angle of the GSA compared with the GS, it collides with the Avant.
On the standard GS the Avant 12GS_LC fits both the standard and Enduro skid plates without a problem.
Fitment of the ADVance Guard to the F800, 700, and 650 GS is straightforward using the contents of Kit ADV-GD-K1-GS. Fitment to the 2019~2021 F850/750GS is more involved in that it first requires installation of handlebar setback/risers mounts (such as those made by ROX, Wunderlich, Touratech and others) in order to create sufficient clearance between the Guards and these new models’ very large TFT displays. A setback mount is essential to prevent damage to the display at full left/right steering lock.
See the photo to understand the tight relationships between the F850GS brake master cylinder and the TFT display. We will update this notice after we’ve mounted a ROX setback mount and taken photos.
All years of 2018 Triumph Tiger 800 & BMW S1000XR use mechanical clutch lever mechanisms
with long levers and correspondingly long stroke travel. These long levers contact the inside of the ADVance Guard shield preventing proper fit and installation behind the Guards. However, there is a solution in the form of an adjustable length aftermarket lever which you can buy to replace your OEM clutch lever.
One such product is the Adjustable Puig Lever- available in multiple anodized finishes. It is available from Revzilla:
Since the 2018 Triumph Tiger 800 & BMW S1000XR need adjustable clutch levers, you must purchase one separately from another retailer when ordering the ADVance Guard from us.
For the Triumph Tiger 800, order ADV-GD-KIT 1-TIGER.
For the BMW S1000XR, order ADV-GD-KIT 1-GS-LC + R-LC.

Please read the information below before placing your order for the MudSling R-NineT to fit the Standard model:
The MudSling R-NineT easily fits the Pure, Scrambler, Urban GS, and Racer models with the OEM shock because these do not have a Preload adjustment feature. However, the standard model R-Nine-T rear shock is preload adjustable and its mechanism is comprised of an adjustment body with knob. This mechanism faces the rear of the bike as delivered by BMW and directly interferes with the coverage area of the MudSling. Naturally, we did not want to exclude the original R-Nine-T from the benefits of MudSling fitment, so an adjustment to the Preload adjustment body position is necessary.
First, before starting installation, we recommend that you take a ride and set the pre-load adjustment to your preference. Then, remove the adjustment knob with a T25 driver (To break the grip of Loctite, you may need to use a Ratchet Wrench with a T25 Torx driver). Hold the knob securely to prevent it from turning while the screw is being removed. Please see the downloadable instructions on the product page for details on removal.
Next, the Preload Adjustment cylinder must be rotated to the right. It is fixed to the shock via a small set screw (see photo). Loosen the set screw slightly and rotate the adjustment body as shown in the photo below, then re-tighten. This position allows enough clearance to mount the MudSling. Do not re-install the adjustment knob because of insufficient clearance between the shaft and the brake fluid reservoir. Any needed adjustments can be made with an 8mm socket or box end wrench. This was a necessary design compromise to fit a MudSling to the standard R nineT model only. The Pure, Scrambler, Urban GS, and Racer models do not have a preload adjustment feature which simplifies the installation process.
Exchanging the OEM shock for a premium aftermarket model like the Ohlins bm440, or bm650 eliminates the clearance issue on the standard R nineT.
Activated Charcoal Filter Canister
BMW equips their bikes with an Activated Charcoal Filter Canister that traps and filters unburned fuel. R-nine-T models are all equipped from the factory with one of the canisters shown below. Early model (2014-16) R9T’s have the larger canister (right) mounted, while 2017+ and derivative models (Pure, Scrambler, Racer, Urban GS) use the smaller canister on the left. The larger of the two canisters also has a module mounted to the top of the canister and their very large size inhibits mounting a MudSling to the early models.
MudSling fits properly to all models equipped with the smaller canisters on model year 2017, 2018, and 2019 bikes without any modification.
The T50 bolts that we supply with the X-Head_LC are 3.5mm longer than stock to compensate for the 3.5mm thickness of the X-Head surrounding it. They are made of 12.9 grade steel and the tightening torque is a maximum 10 Newton meters, the same as BMW’s spec. We’ve successfully tested tightening for strength to 24 Nm. – 10 Nm is not much force! Many customers ignore the instructions and do not use a torque wrench, or use an incorrectly set wrench and over tighten. One more “oomph” for good measure can cause a problem – not only risking breaking a bolt, but also damaging the gasket engine cover gasket.
Once the T50 bolt is set properly it does not move and is not vulnerable to damage. Below are two images showing X-Head’s protective benefits over a wide contact area after a pavement crash at 40 mph. Its 2 layers of material, a thermoplastic rubber liner and a nylon shell, are designed to flex slightly and wear as speed is scrubbed off. The shell will not break. The T50 bolt is protected within a depression below the contact surface level and you can see that there is no abrasion damage around it.
If you have any reservation about installing X-Head_LC properly, take it to a qualified BMW technician to do it properly. You will be very happy with X-Head’s benefits and performance for your R1200_LC model.
Some customers have encountered difficulty fitting ADVance Guards to their liquid-cooled BMW R1200 GS Adventure (GSA). This model, though very closely related to the standard-issue GS, includes a few features that make installation of the ADVance Guards slightly different.
First, the windshield. The adjustable windshield found on the GSA is wider than the shield found on the standard GS. The ADVance Guards can be installed using OEM handlebar end weights, however, the Guards will contact the windshield when the windshield is in its upper-most position and the forks are turned full left or right. If the windshield is generally kept in a slightly lower position, following the included directions will result in a problem-free installation without any modifications to OEM equipment. If full range-of-motion is desired, some adjustments are required in addition to adding the parts in our GSA_LC FIT KIT.
Our GSA_LC FIT KIT includes a longer end weight to offset the Guard further from the centerline of the bike. This increases the clearance between the windshield and the Guard. NOTE: The included end weights have been sized to allow clearing the OEM GSA windshield, but they WILL NOT PREVENT CONTACT WITH WIDER AFTERMARKET WINDSHIELDS. Additionally, the updated handlebar mount in the GSA FIT KIT has a 3rd adjustment position added to improve the fit and reduce tension on the aluminum Guard.
Offsetting the Guard may require adjustment of the lever perches and, potentially, the clutch/brake reservoirs to gain adequate clearance between the handlebar mount and clutch/brake components. In most cases, fasteners only have to be loosened slightly to enable repositioning these parts.
Once all components are positioned properly, carefully tighten all fasteners to fix the Guard’s position. NOTE: Do not over-tighten screws. The threads in aluminum components can strip easily if over-tightened, so for added security, apply Loctite to threads. Be sure to check all clearances before riding and never attempt adjustment while moving.
