You'll have a higher chance of getting struck by lightning than having an issue with the the 4RR.

Stop fearing something that will never happen. 👍

Thanks, something like this helps alot.

Now that I think of it, hopefully this forum post shows up under results when others (however few) may worry about the few blown engines I've seen and go to consult Google or a forum.

You're welcome. I figured it could be a contributing factor to the engine failures. I personally don't follow Facebook or Reddit and have not heard of any engine failures on the ZX4R. I did see a blown 2021 ZX6R on Facebook marketplace but that bike looked like it was used for drag racing so obviously not a normal use case scenario.

As others have said, I've yet to see a member of this forum post their own blown up engine, only heard of one on Facebook.

We've had plenty of reports of incompetently delivered bikes from the dealer, like oil below the minimum mark, I wonder if that's what's happening.

That being said, if you want to see what an actually disturbing amount of engine failures looks like, head over to the aprillia rs660 forums. There is an engine issue thread every other page.

Well, I'm here with some bad news, I just had my 4rr blow up on me last week, and I'm searching the internet to see if anyone else is having issues, it only had 4300 miles on it and I had all the required services done at the dealer, I was easy with it in the break-in period, and I honestly didn't ride it super hard anyway, but here I was going at about 12k rpm in 5th gear and POP, theres a quarter sized hole in my engine block, it should be covered under warranty the dealer said but they also said they're going to have it for months. I'm really hoping that I won't be so unlucky as to have it happen to the replacement engine. I haven't made any crazy modifications that could cause something like this, so I'm hoping this is just a fluke.

It's always to include not only pics, but more useful data like oil change interval, type of oil, octane, ambient temp,and engine temps at the time of failure.

here's a pic of the hole for anyone wanting... hole pic @northof14000 i tried to post it when i first posted but my account hadn't been approved yet. @SCNinja400 and as to the type of oil, i have no idea i just took it to the dealer and they put in whatever they they did at the first break-in service, i didn't ask though i may should have based upon what happened. I was told that i didn't need to replace the oil until i had 7500 miles on it after that first service. the engine had been running for about 45 minutes so it was nice and warmed up, and the temperature outside was probably about 55, octane was 93, thats all i put in it.

Thanks for the picture. Sorry about your bike. Mine has been flawless...so far. I had a new Aprilia a few years back and it blew up within 1000 km. Just after the first service.
Aprilia took it back and gave me a new bike of the same model. Took a while though. Hopefully Kawasaki stands by their warranty.

I could be reading the instruction manual wrong but it looks like oil changes should be done once a year. I took my Ninja in for her second oil change last week at 2,0XX miles. It was the blackest oil I’ve ever seen.

Also for what it’s worth, I use 91 octane like the manual suggests. I once went to a gas station that did not have 91 and I was on fumes. It was either 87 or 93. I chose 93 and regretted it. I would never do it again. The bike didn’t turn over right away and didn’t seem like it was operating normal. I rode home quick to burn as much oil as I could to empty out the tank so I could put 91 back in.

93 has a higher octane rating than 91.
All things being equal there should be no difference between a 91 and a 93 octane rated fuel except for cost.
