Clunking from the rear

[EasyRider]

First off, I have tried the "search" box and Google. But found no info.

I rode for the first time my new to me 2016 R12RT.

When i was on the motorway, about 40% of the time when going over a bump there was a clunk.
You did not hear it, but felt it though the bike from the rear. Both the wife and i felt it when it happened.
It did take the enjoyment out of the ride as i was drawn to it, and was waiting for the next clunk.
I have had a shaft driver bike before and it never did this. I'm thinking it could be a suspension linkage problem.

Any help please would be great.

Thanks Martin

Have you checked the rear shock for wear/leaks? That would correspond with 2-up and the clunk occurring on bumps…
BMW only warranty their susp for 3 years/30,000 miles, whichever comes first, mine’s a 2018 and the susp has been replaced by TT Suspension which is considerably less expensive than BMW.

Thank you. I will tell the dealer i'm buying it from to check the rear shock.

Edit...

Just to add, the bike has 18,400 on it.

Don’t know if you’re aware but there’s an ‘Enhancement’ program (definitely not a Recall !) for (some of?) the RT’s where BMW will replace the footrest circlips, check for problems on the shaft crown wheel, drill the housing and insert a one-way valve, and perform a software update FOC.
The link is here but it will need the VIN number…

If you’re buying from a BMW dealer then they should be aware, if not then speak to a dealership to arrange.

The dealer im buying it from has it booked in to BMW on the 14th December to have to 3 outstanding recall done, The top box brake light fixed and to see where the clunking is coming from. I just have to wait and see. I think the dealer is getting pissed off with me as i keep popping in to ask question. But we are buying 2 motorcycles from them.
