High Fender Mod

I've lusted after Wasp's fender mod ever since first laying eyes on it. I finally gave up on trying to get the parts shipped over, so I ripped all of his hard work and made my own. Why reinvent the wheel? :)

To be straight, I want to make it clear that I have no intention of reproducing these. All of his work is documented in an ADVrider thread. Very nice work. I've tried to get the bits from Greg direct, as he did such a fantastic job on a simple design, but he's moved on to other bikes/projects now. Hopefully this will inspire others that have been wanting this to go ahead and take the plunge. ::008::

This is a prototype with a few bugs, but was enough for fit/finish checks. I still need to get the brake lines/fittings sorted, but wanted to do some road testing on the bracket and fender first. I've put around 100mi on it so far, speed rated to 120mph (some very minor shaking at those speeds), and nothing has fallen off....yet! ::025::

This is laid out in an accelerated timeline, but I'll answer questions to anything not clear. Please forgive the phone pics, they're nowhere near Wasp quality!


Initial flat pattern after some cardboard, measuring, sketching, and cutting:


Mockup bent cardboard, with modified expansion plug:


Cardboard mockup, bolted into place. Note that the expansion plug fits inside the steering stem:


Revised flat pattern on a sheet of 16ga steel:


Pattern on steel via spray adhesive:


Holes drilled:


Profile trimmed with plasma torch. This is crude, but the only quick way I have to do so for a prototype:


Rough edges cleaned:


Bends added:


Paper cleaned:


Test fit for hole placement. This fender is the Acerbis Supermoto two-piece fender. It came as a universal fit, add your own holes. There are obviously tons of options here, but after MUCH Googling, this is the one that suited what I was after best. It fits the bike's lines well, I think.


Bent steel bracket bolted in place for test fit:


Fender bolted up for test fit. Note, ignore the r/h side panel removed. It was removed for another project, and doesn't need to be pulled for this mod:


Final fit. Note, brake lines temporarily routed best case scenario, and zip tied into place:


3/4 view:


As mentioned there are still some things to address, namely brake lines, but I'm real happy with the transformation in the looks department! MUCH better than the stock arrangement, but YMMV. I also plan to fill the void between fender/headlight with some sort of auxiliary LED. Still researching what you all have done here, and found a few that look like they'll work real nice! ::008:: ::001::

Nice job!!!
I like the idea that the mud can't pack under the fender and lock up the front tire.



You may also want to add a baffle to the front of the engine, above the skid plate. DCStrom used a paint strainer from Home Depot:



And I more often see them made of expanded metal, also from any hardware store. Not on a Super Tenere, here it is being used as a radiator guard:

Just making sure, but you have at least 8" between the tire and the fender right?

Remember a fender like that will flex down quite a bit under full suspension compression.

Looks cool and nice fab work!

Thanks. I wondered about adding some sort of screen for the headers and case, but even with the stock fender the whole area gets pelted. My headers pretty much stay caked. It's been that way for the last year, so I'm not too worried about it. Haven't noticed any extra debris yet, but will keep an eye on it. Curious to see what happens in the rain, too. :D

Thanks, I dig it!

Its close, but I think there's enough room. The pics are a bit misleading with the angle. I need to take some better side profile shots. On version 2.0 I'm going to raise the spacing around an inch. That should close the auxiliary light gap for a cleaner look, and give some more room for travel.

Nice job. Was your modification to the expansion plug simply to trim the OD down to fit into the existing hole?

Any chance you have a dimensional drawing of that bracket as flat? ;D

Yes, 7/8" (0.875") was the closest size that I could find. IIRC the ID of the stem is ~13/16" (0.8125"). Shaved it down a bit, and so far...so good. My original plan was to use a drop-in concrete anchor, like below, but none of my local hardware stores carried the size needed. They're available from McMaster/etc, but I wanted something cheaper/easier/quicker for prototyping. That's basically the arrangement that Greg used, only his looked machined to fit.


Another alternative was suggested by a riding bud, and it's brilliantly simple. Run a piece of small all-thread the length of the steering stem. Since the top is open too (under the rubber cover), add some washers/nuts to both ends...and done. That was my backup plan if the expansion plug didn't hold. I was a little concerned since it's so short, but it has held well. I've found a longer version (~2") of the same type plug online, may go that route too.

I don't mind sharing the bracket drawing, I've gotten lots of great info from the site. Happy to give back. There aren't any dimensions on it yet though, let me add some and I'll try to post up a PDF. On second thought, I think I've tried that before with no dice. Shoot me a PM with your email, and I'll send it over.

Gotta wonder if someone would start making the high fender bracket. I like the low fender look but I have low sided because of mud pack.

Now that your lower fork tubes are exposed, do you have plans to protect them?

Mud clearance was just a benefit for me. I haven't liked the look of the low one since I bought it. :D

Wasp made some really slick ones with his mod. I may follow his lead, again, or pick up some from RideOnADV...haven't decided yet.

Why does everyone assume that any time a high fender and/or 'beak' is mentioned, that people have GS envy? If anything, it looks more like a Tiger Explorer than a GS. :D ::)

The GS is far from the only bike out there with a high fender. It's a personal preference. It's a much more aggressive stance, to me, and fits my style of riding better. ::26:: ::001::

Has nothing to do with Beemer fever, at least for me. ::008::

My mud packed front tire lowside cost me more than $400.
