Pissed R1200GS front suspension

I'm riding along through a construction zone today in traffic at about 35mph when all of a sudden I spot a nasty pot hole. No time to react and I go right through it. Holy Jeebus the front end bottomed out with such force and loud bang! I pull over thinking for sure I bent the front spoked rim. Luckily it's OK. This is like the tenth time this has happened since I bought the bike new in August. Is it me or is the front end on this bike too soft? Why so soft, I mean this is a dual sport isn't it? I'm 210lbs right now. I have the ring on the telelever spring at the lowest setting. What can I do to stop this from happening? Is my only remedy to replace the stock WP spring to one with a higher rate? I really like my GS but this soft front end is killing me and the bike. Someone please give me some advice. Thanks

Wow, and I always felt the front was OVER sprung. I am 210 too, and haven't felt this. Are you sure you are actually bottoming out and not just jarring hard? The Telelever suspension doesn't bottom easily!

I have mine set on the lowest setting and have yet to bottom out.

Maybe you need to try avoiding potholes!

Jim what do you mean by jarring hard? Every time it has happened the sound is a very loud bang. Thanks

The few times I have hit a hard pothole I felt it in my wrists, but no banging. Maybe your shock is defective? I can't, even if I want, make my front dive more than 3".

i too have an r12gs, and the roads here in los angeles suck beyond belief. it's like you're running down a concrete/asphalt fire road. my front suspension has bottomed many times. in fact, it's often "packed" itself down because there's too much rebound valving to prevent the suspension from extending quickly enough to recover for the next bump.

i've since replaced my suspension w/ the WP fully adjustable shocks (f&r). a bike costing this much should not have this problem. when installing the WP units, i set the shock compression (high & low speed) to full soft and was able to replicate the "bottoming" problem of the stock suspension. i even put in excessive rebound and was able to mimic the "packing" effect of the stock suspension.

KTM's adventure sucks up the LA crap road w/ aplomb. bmw needs to do suspension testing in los angeles. ford learned a lot on their new f150 when they accidentally ran their trucks along the LA freeways.

btw, i weigh 205 w/o my riding gear.

Son of a beeyotch! I just tapped all the front spokes and found one that is so loose it just spins. I could see stress marks on the hoop at that spoke and the adjacent one. I got the front end up right now and sure enough my front rim is bent a little. I'm going to tighten it back up. Any other suggestions? Thanks

Question Wilbers & Anakees and an unstable front end.

I will be posting more on this later, but I have an R1200GS with new Michelin Anakees and Wilbers. When I turn agressively, the bike will weave at about 3 to 4 oscillations per sec. Several people have written to tell me they had the same problem with Anakees. If anyone else has this problem, I'd like to hear about it.

The other problem could be the sag. Perhaps more weight on the front end to get the bike to settle down???

i better go outside and check my spokes too. we have these wonderful "step" bumps on the freeway here and hitting them at 80+ has bottomed the suspension many times...

I bottomed my front suspension so hard, with 150 miles on the bike, that the front wheel had to be re-trued.
At 230 lbs I was way too heavy for the stock suspension. And BMW implies that we have 7 inches travel in the front. It is complete bullshit. The telelever may theoretically have 7 inches of travel but the forks only have about 5 inches of travel and the service manager at the dealer told me I have 4 5/8 inches of wheel travel total. And when you figure in sag, we do not have much travel at all.
Anyway, I resisted for months buying a new suspension. That was a big mistake.

You guys must ride a lot harder than I do.

Any how, travel is measured from top to bottom. Not from rest to full compression.

Just a thought for those who may not know that.

Maybe I am just fatter. Yeah, I bottomed the front suspension, on the street, often until I replaced it.

Me too! I ride mine in the bush almost exclusively and invariably end up hitting washouts and ruts at speed, my front wheel is starting to resemble an Australian 50 cent piece, but I can't say that I am continually 'bottoming' out the suspension. Maybe I am more of a girl's blouse than I thought I was

There's no way I could tighten that loose one. I'm going to have to tighten all the spokes on the opposing side first and see if that will give it more tension to tighten it. Then retighten all the spokes on the same side as the one that's just spinning. Right about now I'm thinking I should have bought the cast rims instead. Fook me.

have you remembered to loosen off the tiny wee grub screw inside the nipple first?

No, I didn't even see it and I had the nipple off. Thanks my eyes are bad and no experience with spokes.
