Hello everyone,
got my 2022 last Friday, have 300 miles on it now.
When between 2 to 2.5K RPM, and low speed, there is a very loud and strong vibrating knock coming from the engine, it is felt in the handlebar, that bad.

Advised Dealership, waiting on their reply, I already been told to ride the first 621 miles and bring it in for service, then they will check...will try to make the 621 ASAP so I can learn what happens there.

Any inputs on the 2022 K1600 is appreciated it.
Cheers
LCL

Check the out level using the correct method. In fact, if the bike is brand new, change the oil out because it still has the break-in fluid.

It would be unusual, but you can also suspect the valve lash.

I wouldn't touch it or ride it unless you have in writing that the dealer instructs you to ride it until the first service is due. A knock with a corresponding vibration is something that drives me off the bike in no time. What if you lock up the engine and get injured? The dealer will not come forward and tell you that they are responsible.
Park the bike and let the dealer know where to pick it up and not to forget to provide an adequate loaner.

What the gentleman above said. DO NOT RIDE IT until 600!!! Tow it to the dealer. You'll never be able to prove a "verbal instruction" over the phone in court if it ever gets there. Your court filing would say something to the likes of "contrary to the dealer instructions of continue to drive the vehicle, I immediately stopped operation and had said vehicle towed directly to dealers location". Something along those lines.

Also, please keep everyone up to date. There are a number of us anticipating delivery of a 22' model. Hope it's simply a sensor or something else minor!! Also, after the repair, let us know what dealer gave you that God awful, stupid advice.

Not much help, but I have absolutely no issues with my ‘22 K1600B (have 900+ miles on it). I would definitely not drive the bike - just get it to the dealer :-/

For information, Was told over the phone JUST NOW to ride until first service, as it is under warranty and they will check.
I sent them an email with inquiry, specifying all motorbike information and describing the problem and requesting a response from their Mechanics, that way it is in writing.
Will keep you all posed.
Cheers

I don't care what the dealership said, I wouldn't continue to ride the bike when something is obviously wrong with the engine. A loud knocking noise coming from the engine that can be felt in the handlebars can't possibly be normal and if you continue to ride the bike the engine could grenade causing you to go down and be injured. Yes the bike is under warranty and yes BMW would most likely replace the engine under warranty if necessary but what BMW probably wouldn't do is pay your medical expenses if the engine failed and caused an accident. I'd rent a Uhaul motorcycle trailer and get the bike up to the dealership and just tell them you don't feel safe riding the bike until the issue is resolved to your satisfaction.

My .02:

If something in the engine / transmission is knocking badly enough to be felt in the handlebar, it is unlikely to be benign.

We could all spend a great deal of time asking further questions (such as does the knock frequency vary with engine speed, or is it road speed dependent?) and speculating on the cause, but at 300 miles it shouldn't be doing it and a dealer that suggests continuing to ride it as though there's nothing wrong for a further 300+ miles "and then they'll deign to look at it" is, imo, incompetent. BMW's warranty will cover the issue, but it is normal practice that such an issue should be investigated by a dealer at the earliest opportunity so as to avoid unnecessary additional damage - which BMW may argue about covering, with good reason.

Do you have BMW Assistance in the USA as part of the warranty package? If so give them a call, tell them what the issue is and that you are uncomfortable continuing to use the bike. They may say "take it to a dealer", or they may come out to collect it - but calling them is the only way to find out.

I have 853 miles on my 2022 K1600GT. Both my wife and I noticed a knocking sound at lower speeds and lower rpms. When I took the bike in for the run in service I mentioned it to the service manager and he said they would check it out. When I picked the bike up he said there was nothing wrong with it. They took the bike out on a drive and put it through the paces, so if any problem existed they would have found it. Maybe

In certain conditions it there is certainly a mechanical knocking from the engine/drivetrain, but I'm getting use to it (or it's quieting down) and now that the run in is complete the engine moves through that rpm range pretty quickly

Mine sounds like maybe a clutch part or backlash in the drivetrain. Probably wouldn't hear it on a louder bike. I don't feel anything through the bars but raw power and brilliant design.

As the newbie here, I will ask the stupidest of questions (no, not the oil question). Are you running Premium fuel?

On some bikes there is a slight rattle at low load in 2nd and 3rd gear from 1800 to about 2500 rpm. This appears to be gear lash and it is of no consequence. It however does not produce vibration.

I'm running premium fuel. It doesn't sound like spark knocking (detonation) to me. More mechanical clunking or gear backlash.

The '22 have anti-knock sensors. If it's knocking something is WRONG.

Also pretty sure the 2017 and newer bikes run on 87 AKI gasoline as per the manual.

You could do what A.J. Foyt did many years ago. During a practice session something did not feel right so he came into the pits. His Chief Mechanic told him there was nothing wrong so get back on the track. He came in again and the same result.

So he went back on the track and on the main straight with his foot to the floor on the gas he shoved the clutch in. The engine blew sending a rod out through the block. He limped back in and said to his Chief Mechanic “see, I told you there was something wrong”. Supposedly a true story.

Is it driveline lash at low RPM or a Knock?

The driveline lash can be felt in the handlebars.
