Vibration at 3K
Well, 650 miles on my 19 SGS and now getting a vibration when I hit about 3,000 rpms shifting. Once I get to 6th and cruising along it seems to not be as evident but I am under 3,000 rpms. I can pull the clutch at 3K and it goes away. Anyone experience this? Thoughts?

well "650 miles on my 19 SGS"...if it's easily reproducible why not just take it in and have them validate and fix under warranty..does sound like something maybe loose in the Primary but we can only guess but warranty is your friend, unless, well, you know...

I've got a 2018 RGU with 17k miles on it. I ride it almost every day, usually two-up with my wife. I move the engine through its entire rpm range most every time I ride the bike. So, if there were some unusual vibration I would surely notice it. Yes, there are vibrations felt in the foot boards and the handgrips. But these vibes are extremely low-amplitude, almost non-existent. I felt about the same amount of vibration in the handgrips of all three of my GoldWings.
The OP doesn't really describe his vibration, apart from saying it happens around 3krpm, which is where most of us cruise in sixth gear. My bike at a steady 3krpm in 6th gear makes virtually zero detectable vibration. There is enough vibe that I can tell the engine is running, but no more than that. My GoldWings were the smoothest running bikes I've ever owned. The fact that a 2018 Harley tourer can meet that level of smoothness is a real achievement by HD.
So, any annoying vibration at steady 3krpm should definitely be considered a defect. If it was my new bike, I'd take it in to the dealer shop for a looksee.
I might add that, since the OP bike has less than 1k miles on it, it is still breaking-in. My new RGU made a few vibrations and noises that went away after the bike had a few thousand miles on it. A lot of it, I think, was a matter of getting accustomed to the new bike.

Well, it's a noticeable vibration at 3K RPM. Seems to be more prevalent 3rd thru 6th gear. As soon as I pull the clutch in, no vibration so I don't think it is frame/wheels or anything else but engine/transmission, It's going in to the dealer to see what they think.
My 2017 Limited M8 ran smooth so this is noticeable and obviously something is amiss.
Thanks for the feedback.

I'm having the same issue on my brand new 2019 RGS but its at 1800-2000 rpms. Coasting up to a stop when the RPM's hit 2000 the bike starts to vibrate horribly but stops instantly when the clutch is pulled in. Mine only has 50 miles on it and something is very wrong with it. I have ridden several 2019 SGS's and RGS's and this is not normal. Mine goes in on Tuesday to be looked at....

It went in to the dealer today and they are going to discuss with Harley Corp. in the morning. Four Service & Sales employees test rode the identical Demo RGS plus my bike and it seems that something is causing mine to "lug" upon decelerating at 2,000 RPM's vs. the demo bike which did it at about 1400-1500 RPM's. The Master Tech thought it could be the motor mounts tightened either in the wrong order or incorrectly but was just guessing at this point. Its truly the most annoying problem as the entire bike shakes noticeably while decelerating every time I am slowing for a turn or stop prior to pulling in the clutch. I rented a 2019 RGS and SGS for four days and put almost 1,000 miles on them prior to making my decision to purchase a new RGS and neither had this issue. Saying I'm disappointed in Harley right now is a huge understatement! The best way I can describe what the issue feels like is "imagine if you roll off the throttle and when the RPM's hit 2,000 during engine braking it feels as though both brake rotors are warped and your tires have about 150lbs of pressure causing the bike to shake". Keep in mind....this all happens when not applying the brakes & tire pressure is correct! I have owned roughly 30 bikes in my lifetime including several 180hp Ducati's and a 2019 Fatboy S 114...so the issue is not me.

Vibration FIXED!
The dealer has had my bike for two days and was in contact with Harley....so my brand new 2019 RGS has been REPAIRED! While we don't know the exact cause....these three things were done and one of them fixed the issue. 1. The motor mounts were loosened and the motor was allowed to "reset" in the frame. It was under some "preload" when the mounts were loosened so it may have been torqued or aligned improperly at the factory. It was then re torqued to specs. 2. The plugs were then checked and one cylinder was gapped within specs...except one plug was at the minimum and the other at the maximum gap. They were then gapped equally. The other cylinder had one plug out of spec and the other in spec...but once again at different ends of the spectrum. All plugs are now gapped exactly the same. 3. The air/fuel mixture was then reset to factory specs. My problem is solved and I hope this helps others if they are having a similiar issue! The guys at my dealership in SoCAL are REALLY on top of it and didn't brush me off like it was a normal issue....so they did go the extra mile to solve the problem!
