Hi guys,

I recently took delivery of a EX - BMW company bike, a GS 1250 rallye. It has a little over 3000 miles on it. I appreciate that any issues are going to be covered under warranty, but wanted to find out if anyone has suffered the same following issue.

I took it out for its and my first ride today on a road that I know very well that runs out of town from my home. It has left and right sweeping bends and subject to a speed limit of 40 mph. Tipping the bike into a left-hand bend everything is fine and when riding with a bike straight up again the bike is fine. However, when the bike is tipped into the right-hand sweeping bends I can feel what I can only describe as a dry grinding bearing feeling from the bike. As soon as you take the bike straight back up again, it disappears drop it back into a right-hander it comes back. I have spoken to the dealer, and they are going to have a look at it for me. I have checked the tyre pressures, the issue also appears in all gears.

Clearly the previous owner didn’t do much cornering, as the tyre is obviously worn a little in the central part but anything that would have included any fast flowing bend work, clearly hasn’t been done as the bobbles are still on the tire just off centre. I am assuming that this isn’t the issue.

I have been riding BMWs for years both Work and personally, and have never experienced this, which is why it is worrying me on such a new bike. I don’t want to be getting into a major argument with a dealer, as I know this is an issue and I don’t want to be fobbed off.

Any ideas?
 
It felt like it was from the rear… not sure if it’s a duff bearing? Or a final drive issue…
 
I’ve had it recovered by BMW assist back to the dealers. Hopefully they’ll find the issue.
I really do hope this isn’t going to turn into an argument.
If anyone has had similar, I would be interested to hear what it was…
Cheers

If you still had it at home,

stick it on the main stand, and grip the rear wheel at 12& 6 and push pull the rear wheel, and repeat at 9&3

any movement in the wheel is not good, ( i believe the mothership allows up to 1mm) but i had my hub rebuilt by mikeyboy

when i had movement in mine
 
My 2014 and 2018 gsa's both suffered from corrosion in the drive shaft joint at very low miles (in the first 12 months) and it made the rear end feel very rough

2018 needed the joint replaced as it took over ages and some brute force for the techs to get it apart.

In both cases bikes had never been off road and the final drive gaiters were intact
 
I hope that you soon get it sorted to your satisfaction. It’s an interesting one, please let us know how you get on.
 
Possibly totally unrelated but in the past I had a rumbly sensation on cornering which was down to the tyres, Tourance, being past their best. New tyres and it returned to being as smooth as any other tractor!

Mind you, it got rumbly on both left and right handers.

Hope you get it sorted

My 2017 r1200gs rallye had exactly this. Never did get to the bottom of it. Had repeated visits to the dealer, shaft open, bearings all checked. Couldn't find it. Could only assume tyres but wasn't convinced.

+1 I had a similar issue on an older 1200, on both turns, also a strange thrumming noise/vibe at around 60ish - turned out to be caused by the Tourance tyres - who knew!
 
Joint stuck on splines and actual UJ heavily rusted in both cases

So what was causing the vibrations ? The spine or UJ , your term, Joint ?
My bike developed exactly what was described above. Dealer told me it was the tyres. It was only when the tyres were changed I believed them ! I cant see how a rusty spine can cause vibrations ? But could understand a damaged UJ.
 
Got my 2021 Rallye in July last year, it came with Michelin Anakee Adventures. I wear earplugs but could still hear tire noise when leaned over, but not in a straight line oddly enough. Could it be the grinding your sensing is the tire vibration when leaned over?

No idea which it was as both bikes had the same issues and once the UJ was sorted and the splines cleaned and regreased (or should I say actually greased ) the vibrations were less noticeable and the final drive became much smoother
