Sudden loss of power

I was riding on 610 today going about 60-70mph, RPMs at 6-6.5 and the bike completely lost power. First time it happened I thought I accidentally pressed the engine killswitch button. I turned it back on and rode not even half a mile when the exact same thing happened. I looked at the killswitch and it was at the on position so it couldn't be that. What is wrong with the bike?

I waited for 30 mins and rode back home. I rode at 50-60mph and kept the RPMs less than 5k for about 10 miles. Then rode 14 miles more at around 40 mph. Didn't have any problems on the way back.

The bike is an 09 Cbr600rr.

What is wrong with it?

Any help would be appreciated.
Thanks

Edit: When it turned off the rpms went to 0 and only the oil light came on.

Edit #2: About 3 weeks ago I was riding and the tachometer stopped working. Just shot down to 0. The bike was running fine. When I got home that day I turned the bike off and on and the tach worked fine. Never had that problem since. Thought it might be related?

Sounds like a battery. Check your connections. Also stator.


Is it throwing a code?

That sounds like a short. New to you bike?

Any thing else hooked up there ? HIDs? Juice box?


Check wiring harness connections. Check kickstand. Not bent or damaged.

Put ur bike on neutral and start To accelerate and if it turns off then the problem is the kill switch.. I used to have the same problem with my cbr1000 and I changed that it cost me about $50 but that solved the problem for me.

check the battery output.....you can tell if you have something wrong with the charging system if the output goes down.

But judging off the fact that your tach stopped working id be looking into something up there possibly shorting out

sounds like a rectifier or stator. Check voltage while the bike is running if it starts to drop one of the two is dead.

Just tried that, nothing happened. I kept it at 6-7k rpm but it didnt turn off.

Problem is I dont have any tools to do anything...

Also kickstand is not bent or damaged. Bike didn't throw any codes when it turned off.

All fuses working properly. Checked for loose connections. Tried checking the battery output with the bike turned off but the voltmeter i have is and doesn't have decimals. Reading kept changing between 12 and 13.

Pull the on/off switch apart and make sure there is nothing loose in there (if you havent already)

I've experienced the exact same problem. On my '94 ZX6, it was a loose connection on one of the ignition coils. One coil fires two cylinders, and one of the two coils is also the pickup for the tachometer. My symptom is partial loss of power (no spark to 2 of the 4 cylinders) and the tach went to zero. Check the low voltage connections on the coil. Mine are spade lugs which I plan to replace soon as it happened today briefly.

Thanks all.

I'm going to try and ride it to Motorcycles Unlimited on monday to have it checked out.

Not gonna try to do anything to it since I'll probably break something else if i do.

Difficult to say.
Since it starts right back up and runs fine I can probably rule out tue battery.
Sounds like a loose/corroded electrical problem.
Check the battery cables and make sure they're tight.

It might be that..

I rode the bike a couple of times and I'm noticing that it lacks some power.

Apparently the bike has an extended warranty so I took it to Wild West Honda. A mechanic there went for a test ride and said it turned off on him twice but the power is fine. Which is weird because I've been riding it since it turned off last time and it hasn't turned off..and there is a noticeable lack of power.

We'll see how it goes, so far things don't look promising. It's good that the bike still has a warranty but I preferred to take it to a small shop like Motorcycles Unlimited or something else.

Just came back from Wild west honda...they couldn't figure out what's wrong with it. Service guy said he connected it to a computer but no codes.

He said its not lacking power but when I rode it home it was obvious the bike was lacking power.

I'm stumped.

So it died twice for the mechanic at Wild West Honda then they told you they could not figure it out and sent you on your way?

Note to self.... don't take my bike to Wild West Honda.

I honestly think he just hooked it up to a computer and checked for errors and that's it. I could be wrong though. I still wouldn't take my bike for service there again for sure.
