The issue was not there untill recently.Upshift

Good point..in first gear there is a hesitation to rev past beyong 5000 rpm.Can you accelerate normally in first gear?

I will check. Thanks.Did you checked front engine mountings? Loose bolts could explain the vibration issues.
It's normal for the motor to lose power in first gear at those high rpms. The higher the gear the happier i it is at higher rpm and will bog at lower rpm. Upshift sooner out of first and upshift later through the rest of the gears. Try it and you'll see. That's where the bike is happy. I shift out of first right away and live between 3-8k through the rest of the gears. Experienced riders here will verify that this practice makes a happy motor and a fun riding experience.Good point..in first gear there is a hesitation to rev past beyong 5000 rpm.
I see your point. But the issue I described never existed a few 100 miles back.It's normal for the motor to lose power in first gear at those high rpms. The higher the gear the happier i it is at higher rpm and will bog at lower rpm. Upshift sooner out of first and upshift later through the rest of the gears. Try it and you'll see.

Actually that rings a bell. The previous owner used to ride the bike very sedately but I have been doing hard accelerations eversince I bought it from him. Now the bike has poor throttle response under 3000 rpm but better than ever throttle response above 3000 rpm.Then I would say that up until a few hundred miles back you had a problem and now the problem has corrected itself. I'm not trying to be contentious, but I'd say that you should take your bike out and ride the way I have indicated. I believe you'll find no issues at all riding that way. If you do have something to report after riding that way then we'll have something to work on. Until then, I say user error. No offense meant. Just my 2¢.

In first gear, it is difficult to rev past 5000 rpm because of vibrations. In higher gears the vibrations are less intense hence I can confidently rev past 5000 rpm. All these vibration issues and poor performance started a few 100 miles ago only.When I had my 500 I made a habit of "riding the flat of the tach": Look at the tach -- it's a hockey-stick, with 0, 1 and 2 on the stubby bit, 3 wrapping around the curve and 4 through 10 thousand RPM on the flat, "table top." The engine will be happiest operating on this flat part of the tach. Below that and you're in lugging range and it's going to feel rough..
As a 180-degree P-twin, the engine sees two power strokes spaced 180-degrees apart followed by 540-degrees -- one and a half rotations -- of spinning down without a power stroke. Because of this, 180 PTs can feel pretty rough at low RPM.
I'm a bit confused: Over your posts in this thread to date, you seem consistent with the feeling that below 3K RPM the engine is rough and performing poorly below 3000. But early on you said "in first gear there is a hesitation to rev past beyong 5000 rpm" and then said response above 3000 is "better than ever."
You indicate the roughness and **** response below 3000 is new so perhaps there's something wrong. At low RPM fuel demands are relatively low but cylinder pressures can be high if you're feeding throttle so, if there is an actual running problem, it's likely to be a ignition related; coil boot is leaking spark energy, plug insulator carbon-tracked, gap is fouled etc. If you feel weakness when accelerating -- the 500 has a pretty flat torque curve from 4000 to 8000RPM so it's not really natural to feel it wheezing -- you might look into airflow (clogged air filter or air inlet) or fuel delivery.
Use your gears!! I bought my 2013 CB500f when it had done 13,500 km. and it was not happy at such low revs. The only difference in performance that I have noticed after 188,000 km is that will happily cruise in top gear now at about 2,500.revs.Recently I am having rough ride and abysmal throttle response from my 2017 Honda Cbr500R - 3400 miles.
Feeling vibrations as well under 3000 rpm.
Engine, coolant levels ate good.
What could be wrong. 😣😣😣
Oil was changed at 1000 miles. Next oil change is at 8000 miles right?At 3400 miles, if not already, change the oil. Use premium fuel.
