Hello, I read that some found the vibrations on the model prior to 2020 really bad on the highway like fingers numbing ...

I consider to buy that bike as a first bike (46 years old, 245 pounds, 5"9") .. and I just want to make sure I will be able to do long trip if needed without the need to stop every 30 minutes to feel my fingers again

Thanks.

I'm not an expert, it's first bike for me but I don't feel too much vibration at high speed, not as bad as feeling pain 30 minutes later. I would be more worried about air... highway+speed=air. Air can be more painfull after 30 minutes than vibration I think.

The vibrations are annoying during break in, so the first 600 miles. After that it smooths out and I dont notice them at all anymore. Its a very smooth bike. Also, ive done 1-2 hour trips a few times on the Z and ove never had any issues with wind fatigue or vibration numbness. Just a stiff butt. Thats normal for any bike though.

I have the 2019 and vibrations are noticeable on some of my longer rides on the freeways. I get numb hands if I ride on the freeway for more than an hour or two. Not sure if it's just my bike.

I should note that I do wear leather gloves, and am meticulous about my suspension settings as well my rider ergonomics. I've found that not having the right handlebar angle, fork height adjustment, and rear preload can really make the bike tough to ride. Alot of reviewers dont go in and dial their personal settings in... so theyre reviewing a bike set up for someone else. I went a step further and got heavier fork oil and adjusted the factory preload spacers on the front fork and its really enhanced the quality of my ride. Vibes werent bad before, but after all of that Im just floating through space (in a good way).

My 2017 Z650 seems fine. I have ridden it for 12 hours in one day (at a good clip), with no problems. BTW, the seat is evidently very well shaped to prevent discomfort on such a long ride. Personally, I like a little bit of vibration, to remind me that the machine is run by an engine with character. But any claims of numbing vibrations are probably overblown.

It's hard for me to believe how spoiled some riders apparently are. You'd think they have never ridden anything smaller than a Gold Wing. Motorcycles vibrate, period. Some are worse than others. But among parallel twins, the Z650 is one of the better in that regard. Keep in mind -- just as with many other things -- that complaints, bad impressions and experiences of motorcycles get heavy play in online reviews -- while the vast majority of owners are perfectly happy with their bikes and never post a peep.

Just joined, hence the late reply, but here's my bit:
I do pretty frequent highway bouts, and the vibes aren't THAT bad relatively speaking. If you want to mitigate them some aftermarket dual-density grips like the ProGrip 719 REALLY cut down on the feeling in your hands. Honestly, those grips are probably the best $15 I've put into this bike.

To clarify my earlier post, I tend to hold the throttle with my hand really far to the right, with the end of my hand on the end of the bar end. This tends to exacerbate the vibration since the bar end has no dampening when compared to the throttle grip. So I’m a special case lol.

I have the 2020 Z650. I don’t mind the vibration. There’s always vibration in twin cylinder motorcycles. If you hate vibration, you buy yourself a 4 cylinder goldwing. What I really want to eliminate is wind force on my fullface helmet which makes my neck so tired after a long ride on the freeway at speeds over 75 mph. For eliminating numbness of my finger, I bought this:

And this for stress-free right wrist:
