Luckily I can order directly with Wunderlich Germany (or via my BMW dealer), so the extender only costs me €60 ($66), and some more of course to have the dealer install it.

But after all the good reviews here it was an easy decision to add this to my GT.

My wallett thank you for letting me know how cheap you can get them for there lol. As you mentioned, with all the positive reviews I dd not think twice, one of the great reasons to belong to a good forum.

@Gaucho, are you in Germany? Here in the U.S. it's a $115 (€104) item.

In the first weeks of ownership, I installed the Fenda Extenda IIRC. Likely from Twisted Throttle. I haven't had issues with the tire wearing it or vice versa. I may have taken some forum advice and used a heavier duty two sided tape in addition to the plastic "rivets" provided with the kit. So far so good after 11k miles.

35.00 is a very good price and it looks sharp !!! I wonder if it fits 18 GA.
It should, I bought one off eBay for about $25-35 and it appears to be the same as all the others. I reinforced mine with an aluminum strap and added screws. No rubbing or flopping around that I can tell. Don't even notice it anymore.

Here is my post with a couple of pics.

I prefer your reinforcement strap than the L bracket supplied with the fender extender. Thank you for posting that and the photos.

Here are the steps of how I mounted mine:

1. Wash both fender and extender with warm soapy water thoroughly. Then wipe the mating surfaces with rubbing alcohol. Mark a line on the fender of where the extender will go.


2. Roughen the mating surfaces with sandpaper. I used 220 grit this time, but anything between 80 and 400 would work. This step is crucial for giving the adhesive max surface area to grab onto.


3. Masking tape both sides to shield from glue overrun. Make sure you press down the edges tight, otherwise the glue might seep under the tape.


4. Apply adhesive of your choice. I prefer Polyurethane glue (Gorilla Glue) for several reasons:
a. Bonding strength is extremely strong.
b. Very lightweight.
c. It expands as it cures, filling gap and getting into all the nooks and crannies. This is especially important for this fender because there are good size gaps between the fender and the extender.
d. Once it is cured, it remains somewhat flexible, which provides a good bit of impact and vibration resistance.


5. Apply first application of glue sparingly. Then press the parts together to check where additional glue may be required. Apply second time to those areas. You want sufficient glue to coat all mating surfaces, but too much glue will squeeze out, overrun and make a big mess.


6. Press the 2 parts together. Once you are satisfied with the fit and alignment, tape the mating edges to "lock" in the fitment. Now clamp the two parts together. You want sufficient clamping to bring the mating surfaces as tightly together as possible, but not to much so as to warp and twist the parts out of shape.


7. Wait 6-12hrs before removing clamps. Curing time depends on ambient air temp and moisture content. When in doubt, give it full 24hrs.


8. Some glue expansion and overrun is a good sign that you have max glue coverage, right up to the mating line. Unfortunately, this also means taking off the masking tape can be rather tedious, as any glue overrun along the edges will cause the tape to be difficult to remove. Careful picking with a sharp hobby knife works well here. The tedium pays off with a clean, tightly bonded, lightweight, and rigid assembly.

Mount the fender back on the bike. The 4 bolts allow a good bit of fore-aft movement of the extender. Because there are no fasteners and the assembly is very tight and rigid, I chose to close the gap between the extender and the tire as tight as possible. This will help give as much clearance to the cowling to avoid interference hit.

I've installed some 8-10 of these carbon fiber fender extenders from Blue Bird Engineering. These Spaniards really know how to lay some good carbon fiber. Here are a few of the other bikes I did. All worked very well and proven durable.

No problem. Just thought I'd offer folks another option. There is more than one road to get to Rome. :smile:

I bought a $30 FendaExtenda, heated the end with a heat gun and rolled it over a piece of 1/2" dowel to curve it backward/ Stiffened it up and no rubbing on the tire.

I installed the Wunderlich unit within a few days and maybe 200 miles of bringing the bike home.

I'm not sure there's any difference between early and late model fenders and radiators. Though I'm out of spec for the years you're looking for information, my 14 GTL/E has the Wunderlich Fender Extender. It's more then just the ABS piece that glues/rivets into position, it has an ancillary bracket that keeps the extender from rubbing on the tire by keeping it up and away from the tire. The bracket is attached to the fender via a two new holes you'll have to make into the fender. Here's the US website for it. Fender Extender K1600 (#32211002) Wunderlich Editions 32211002 | BMW Wunderlich America

This accessory is expensive compared to the other extenders and that's due to capitalism and the extra bracket. I had the less expensive one and it rubbed against the tire at higher speeds which caused it to be noisy. I replaced it with the Wunderlich. It has been doing its job without issue. My fender is much less beat up now with dirt, and the radiator is not getting nearly as dirty as it was previously. Honestly both the Wunderlich and non-Wunderlich extenders are about the same size, but that bracket makes all the difference.

If you've the resources to fabricate a bracket for the Chinese brand, I seriously doubt you'd see any difference between that and the Wunderlich. You can see what that bracket is and how it mounts from their website (http://www.wunderlichamerica.com/instructions/32211002.pdf)

The only thing you'll need to remember is to tell who ever is changing your front tire that the bracket is there. That's because the front fender typically comes off with the 4 Torx screws before they can remove the tire from the bike. The fender extender is now attached to the bike while normally it isn't. While not required, I ask the tech who's reassembling my fender to put some type of non-permanent thread-locker on the one screw that is needed to be removed for disassembly (picture #9 in the instructions) of the bracket that mounts to the bike (leave the two screws that attach to the fender alone). Here in the US Loctite® Threadlocker Blue 242® is commonly (but not exclusively) used Loctite Threadlocker Blue 242 from Loctite Adhesives

Good luck.
You don't have to remove front fender to remove or put back on front rim/tire.
