rpm

I’ve had my 2026 CBR650R for a few months now, and it makes a “strange” sound when I downshift around 4,000 RPM. This only happens between 3,500 and 4,200 RPM, and it’s like when I downshift with the eClutch, I hear a double click—one loud and one softer. Is this normal?

Hello, I picked up my 2014 CB650F 30k miles, 1 owner FSH (had early valve check) yesterday and having a blast. I’ve noticed some chatter at low rpm (1-2k) and when I’m engaging the biting point on clutch. Want to post here as I presume it’s normal engine noise but I’m not used to the bikes...

I have a 2016 CBR650F which has done 30000km. The bike is completely stock. Spark plugs were replaced at 20000km. The bike acts weird when the engine is cold. There is a bogging that is felt at 2000 RPM if I rapidly increase the throttle as if it's running out of fuel. If it slowly increase the...

1. When the bike is stationary and in neutral (N), the high-pitched noise does not occur. 2. While riding, the noise appears at around 4000 RPM in all gears (1st to 6th). 3. The noise occurs only during acceleration (when RPM is increasing) and disappears during deceleration. The noise can be...

my cbr650r is jerking at 8k rpms as if its cutting power or restricting the rpms. I am able to push past this sometimes, but I don’t know what’s wrong with the bike.

I'm trying to locate the rpm gauge wire and can't figure out which one it is. This is from the manual and I'm not sure which would be it.

Hey all so I was checking my spark plugs and coils cause my bike was bogging intermittently. Anyways I took the airbox off and I also checked my fuel pump and injectors and cleaned everything up and when I put it all back together my bike suddenly started starting at 5k rpm and randomly revving...

Hi everyone, this is my first post. Since a picture speaks a thousand words, I thought a video speaks even more. It doesnt matter what gear is in, at 8-9k rpm range i get this rattling sound. When I drop to lower than 8k or go over 9k it goes away? What could this be? Do your bikes also sound...

Hello, I have a problem at high RPM — when it reaches about 8,000–9,000, the ECU restarts, voltage drops, and the instrument cluster also restarts. It seems that some component goes into a short circuit. Has anyone experienced something like this? There are no DTCs.

Hey everyone, Last week, I was riding with my backpack, and she mentioned hearing a strange noise when I closed the throttle. I hadn’t noticed it before, probably because I ride with earplugs and music on. We did some testing, and it sounds like a single loud click—almost like something getting...

Howdy, I purchased a 2024 cbr650r with the e-clutch in November. It’s a great bike but ever since I owned it, if you rush up to 8000 RPM the bike will not accelerate past it. It cuts the power and abruptly reapplies power and so forth until you let up on the throttle. A service advisor told me...

Hello, I bought a new CBR650R 2024 with E-Clutch a couple months ago and I drove about 2000 Km. It had it`s first service around 900 Km. When I`m driving I notice there`s a vibration sound and it`s bothering me. The bike seems fine but it sounds like somethings lose at the front, like a...

I recently bought this from an authorized reseller. They installed the restrictor kit on-site. However, after getting it home, I noticed that the RPMs are unusually high. It starts at 1,000 RPM but then accelerates to 2,000 RPM on its own. I need help figuring this out—any advice would be...

Ive noticed recently that at WOT the bike will break up from about 10k rpm to redline. It almost sounds/feels like the traction control is cutting power but it's obviously not. No issues below 10k rpm. I have a black widow exhaust with 300mm slip on, stock air filter, not tuned. The bike ran...

Hello from Sweden! I have a 2015 CBR650FA with 6400 kms that is well maintained. Recently I have started to notice vibrations when I let go of the accelerator. The vibrations are more like there is nut lose somewhere rather than the fine vibrations originating from the engine. I have read some...

I have 18’ cb650f and im having what i think is a lean bog issue. It only happens while under load and under 6k rpm, if im just cruising and then go WOT (wide open throttle) it bogs (sounds like it only fires off 2 cylinders) and barely accelerates until it gets into higher rpm and it clears up...

The motorcycle sounds like a wolf's spirit is mixed somewhere inside the engine at this RPM range lol. Its more noticeable in 4th-5th and 6th gear. Is the motor suffering if prolonged at this range? Its probably normal but has anybody else noticed that?

2019 model 8,000 Miles, soulds like a tappet noise, Oil changed every 2,000 miles, it's So irritating driving at normal speeds as it's always in this rev range, Anyone else ?

Hello. I'm from Russia, sorry for the translation. I had an itchy, rather strong vibration at high speeds, which is written about in the forum, but there is no solution, I tried everything but could not get rid of it. The motorcycle accelerated very well. I read all the forums, but nothing...

Hello guys, I have a 2018 CB650F with 18k miles bought second hand. From the first day I noticed a rattling sound like timing chain or similar in the range of 4500 to 5500 rpm. Outside of this range, everything sounds OK. I'd say it's a bit more noticeable before the bike gets warm. Is this a...
