Front wheel wobble
« on: March 23, 2015, 05:09:50 pm »
Hi my esteemed and learned friends...

My front wheel has developed a wobble which i initially thought was an unbalanced rim. On closer observation, it seems as tho the wheel wobbles and this is causing a fair amount of head shake.

I have read about loose spokes, could this be the primary cause of my wibble wobble??

Please share thoughts....

thx

Let's start with the elimination process

Tyres, are you due for a new one ?
Have  you checked the pinch bolts bottom of the front forks might have rattled out ?
Any dents on the rim ?
Run fingers over the spokes and make sure they sing a tune! If not they might be loose and need to be tightend and trued
The steering damper still there and not rattled loose ?
Check tele lever and make sure all in order

Tyres, are you due for a new one ? fine for another 2500km
Have  you checked the pinch bolts bottom of the front forks might have rattled out ? checked and are fine..
Any dents on the rim ? Nope, nothing found..
Run fingers over the spokes and make sure they sing a tune! If not they might be loose and need to be tightend and trued Not to sure how they should sing, but a consistant ping as i spun the rim and held my fingers against the spokes?
The steering damper still there and not rattled loose ? tight as a nuns @#$*
Check tele lever and make sure all in order Seems fine to me....

Eish, so where can I take it to have it checked out??

I have been here and done that. What year is the bike, how old and what is your mileage?
When does the head shake happen? At what speed, while cruising, acceleration or free wheeling? If free wheeling are you holding the handlebars? I ask all these questions as I had the same on my 2013 LC and got one of the first one's in SA. I made a video and got the dealer to show BMW SA and AG and after some debate they did a buy back for me. I paid R30k and got a new bike. My new one still has a mild shake but not as bad as the old one! Take a video and should anything happen to you God willing not, as a result of this, you have a claim against BMW if this is deemed to be the cause of the accident. The minute I produced a video, they came to a decision quickly.
It must still be under warranty so BMW must sort it out for you. Good luck and let us know the outcome.

yip Plaky is right, if the usual suspects are in line and accounted for.

Then not sure what else,

Suspension setup might also play a part,

You have not by accident setup for two people and only you riding. As the bike will sit higher and weight will be on the front wheel

hi there,

Shake starts from around 80kph and is very noticible at 120kph upwards. I dare not go over 160kph.

Ride mode is single rider no luggage and on normal setting. When I veiw the wheel while riding i can see what looks like a slight buckle, but its so hard to focus n ride at the same time.

Perhaps best thing to do is to take it in to BMW.

What tyre do you have in front? Something like an Anakee 3 does not affect the bike at all, but a TKC or E07 might be more vulnerable to shaking. New road biased tyre, balance and checking that the wheel turns true might be a starting point?
BoosterPlug, LED Spots, Tool Tubes, RustStop, Kappa Screens, Top boxes, Tank Bags, ATG Gear - whatever works for me.

Your bike have a steering damper,  so no. older than 16 months or so,  so must still be under warranty.  Take it to BMW.

Vat die bike terug na BMW dat hulle dit regmaak. Tensy jy betaal met geld wat Wobble, maar solank jy met regte geld vir die bike betaal moet hulle hom regmaak. En ek glo BMW sal dit doen.

Try pushing up your preload to Rider plus Luggage  to see if it is preload related - does it get better, worse or stay the same? Also, if you have a topbox, take it off and test again.

Brett don't even waste any further time, you are risking your life, as I said take a video of the headshake from 80km/h to 120km/h and see if you can take one also close to 160km/h and give it to BMW. Post on the BMW SA site as well. The more exposure the more likely they are going to sort your issue out quickly  This hectic and BMW has to sort this out even if out of warrantee, they are at huge risk here should you have an accident. I had Metzlers on my old bike and same, just not as bad as yours I gather. Geez boet you looking for kak not sorting this out. The video is key! Let us know how it goes, you are welcome to pm or phone me if you want to.
