Hi. I have a 2024 CBR650R and I looking to buy a good oil for my annual service. I was thinking about Motul 7100 10W30, but is there anything better on the market? Any recommendations? Thanks.

Hi everyone, I'm hoping you guys can help me figure out a weird issue with my 2016 CBR650F. It has about 48,500 km (around 30,000 miles). For the past few weeks, I had a strange issue. Sometimes when I'd start the bike, the check engine light would stay on. But all I had to do was shut the...

Hi, any take on this? Yamaha patents 'fake' engine for electric motorcycles

I recently bought a new 2025 CBR650R with the e-clutch. Everything was fine at first, but just a couple of days later—after riding about 520 km—I noticed the engine warning light came on. I checked the error code by counting the blinks in diagnostic mode, and it showed 13 long and 3 short...

So I’ve had my cbr650f for a few months now and have recently started getting a flashing engine light (flashes twice every 10 seconds in neutral and is constant when in gear and driving) and bad rev symptoms at around 2.5k rpms it sticks there until I brake or pull in the clutch a certain...

Hey all, I have recently engine swapped my 2016 CBR650F due to the engine blowing itself up. Refer to my previous posts about what I did. I have successfully put a 2015 CBR650F engine in, due to the 2021 CBR650R engine missing the hole for the VS sensor. After installed it, I followed the...

Recently, I had to swap my exhaust back to the stock one and then reinstall the custom setup. After doing that, I started hearing some engine noises. When cold and idling, there was a clicking sound, and while driving, it resembled a sewing machine. After some research, I found that the issue...

Hey guys, I just noticed this leak near the engine and I couldn't trace it. Any ideas where it might be coming from ? Thanks

I went on a roadtrip in the south of France last weekend with a friend, had a little (too much) fun on the bends, and lost grip on a right-hand bend. My front wheel exploded, the front brake lever, the spider and I fucked up the right side fairings, the brake pedal and the exhaust are bent...

Hi All, I've recently stripped my CB650F 2018 engine down and found scoring on a couple cylinders and gouges on their pistons. Looking like it will be too expensive for any shop to rebuild it respective to its worth. I've found a CBR650F engine of the same year and was wondering if the engine...

My CBR 650 is making a tapping sound and the engine light is blinking when idling. When I go riding, the engine light stays on but does not blink and the tapping sound speeds up. I did some quick research and saw that the code was related to a faulty O2 sensor. When I took a look at it, the...

Hi, I was being a bit of an idiot and ran the bike for way too long without checking or replacing the oil. At 6,700 miles I had a rod go through the engine case as you can see pictured below. Now I'm looking for a replacement engine to do a swap and coming up kind of empty. Does anyone know of...

I have a 2016 CBR650F, which I only bought roughly 4 weeks ago. I purchased it at 15000kms and have ridden it up to 17000kms as it is my daily. It has been derestricted and tuned. I was slowing down for my exit off the highway, and I started smelling something off. Kept slowing down and...

Hi fellow riders, I just started riding and bought a cbr650r from 202 last week. Since yesterday the engine check light turned on. Went to the dealer this morning and they gave me a paper were it said code P0914 and P0600 they were not active anymore. The dealer removed the light and told me to...

Hey all, I’m a 2019 CBR650R (RH01) owner currently searching for a replacement engine. Unfortunately I'm having a difficult time finding any RH01 motors locally and I've only found 1 listing on eBay as of this post and the RH03 (from 2021+) doesn’t seem to be compatible due to changes in the...

Hi, my 2017 cb650f has engine troubles and I'm planning on swapping it out for another from ebay. Are all RC74E engines the same and interchangeable? Even if it's from a 2015 bike, even if it's from a cbr650f? No timing differences? No issues with ECU?... Thanks

I'm wanting to change the engine cover bolts with black ones, and the only option I've found, are the Pro-Bolt kit for year -21 to -23 CB650R. Will this be fitting my -19? Or should I be looking at the kits for the -18 CBR650F?

Hello friends, my motorcycle is CBR 650 F 2017, the engine warning light is on, it is on constantly and there is no service nearby, how can I fix this problem, thank you

Hello all, I ride a 2021 CBR650R that I’ve had for just over a year. I recently blew up my engine due to poor maintenance. The bike had +10,000KMs on the odometer. I have just bought a 2024 CBR650R engine with sub 2,000kms odometer to swap in, however my first big roadblock is that the CKP...
