Eh? Acerbis front fender on R100GS

I got the Acerbis "mud guard" front fender to mount to my '94 GS. The GS has the low fender right now with the brake lines attached to the fender. There is no mounting braket with the new high fender. Have any of you used this fender and if so how did you mount it? The instructions show a good sized mounting bracket on the top of the new fender but did not come with it. I called Cycoactive but they did not have a clue. Also, how did you mount the brake line?

Check out the diagram available at Max BMW

http://www.maxbmwmotorcycles.com/fic...p?mospid=47932

and see the "MUDGUARD-FRONT-EXTENDED" daigram to see the stock BMW mounting parts...

Touratech used to sell the mounting stuff with the kits (back in 1999 when I worked with those guys...) and I believe the Acerbis makes a mounting kit for their fender as well, I believe you use the tapped holes in the bottom of the tripple clamp.

Here's what I was thinking of



available for $39.95 at

http://store.yahoo.com/motostrano/acfrfebr.html

or $27 from:

http://store.azmusa.com/16008100.html

Let me know what you do, I want to do this mod as well.....

There is no mounting bracket. There are four 6mm holes in the bottom triple clamp to mount a high fender. I took four bolts and used a grinding wheel to make points on them and threaded them into the bottom triple clamp, aligned the fender, them pushed it against the points to mark it.
Retain the low fender brace to use as a fork brace otherwise you will get a lot of fork flex, or order a fork brace from San Jose BMW.
The lower brake hose mounts are part of the fork brace.
I also used the Acerbis plastic fender brace to stiffen up the fender, there is a metal one available too.

The brace that Solo showed is the one in the Acerbis instructions. I'll have to decide which way to go on that.
Thanks, Norton73 for the photos, that shows exactly what I need to do.
I'm leaving on vacation Saturday morning so I'll wait to put the fender on till after I get back. I will probably go ahead and order the parts though.

I got the fender as a Father's Day gift...came from Cycoactive (Touratech).
I did get a reply from them saying they have the plastic brace for $15 but you have to call and ask for Tom or Nick. It comes from Acerbis and Tom says no brace is really needed.

I got an email from AZ saying the brace won't ship for 1-2 weeks. Guess it's a good thing I'll be gone on vacation and won't have time for it anyway.

Thread rehash...

I just mounted up a Cycra fender intended Honda CR's on both of my R100GS's. They went on without any issues and only required a little trimming to clear things around the engine guard bolts, etc. Eliminating the horn's mounting bracket may be neccessary but I only had to do this on my non-PD bike. I'll order a brake line standoff in the coming days but for now a zip tie and a piece of old fuel line is working just fine.

$19.99 from Cycle Gear:



So far I've found no need to run a stiffner and the mounting is rock solid. You will need 4 M6x20 or 25mm bolts.

*Tip: If mounting the fender on a PD you can use the factory support bracket as a template for your mounting holes.

You can mix and match colors. I think they're 25 bucks

So wait, when I tried my version of this same fender (only mine's a Honda OEM fender)

The honda holes didn't line up with the BMW holes.

Did you just mark and drill new holes in the Fender?

If so how close were the new holes to the existing hole.
When I glanced at it the other night it looked like the honda holes
would be too close to the new holes and it would weaken the fender.

Was this the case on yours?
