Ignition Switch On High Pitch Sound and Engine Off

[tomsimmons]

On a new 2023 RT1250 with 35 miles. When press button on ignition switch to turn on accessories I get a constant no stop high pitch sound. What is the cause?

Welcome to the forum!
Any chance it’s the fuel pump that you are hearing?
Usually a 3 to 5 second “run up” as the bike gets ready to start. Not sure if it’s the fuel pump on that bike or why it would run longer.

Honestly if I had a brand new bike with 35 miles on it I would be letting the dealer have a look and listen.

I hear the high pitch sound after the fuel pump shuts off.

Yes I am taking it back to dealer tomorrow.

If your bike has a radio, it’s not “half” on?

There's nothing wrong with your bike. My bike emits that same noise and has been doing it for 32k km. I don't know what it is but I don't care.

My '17 RS does that, too (49,000 miles). I can barely hear it after the bike gets finished with it's various "clicks and squeaks" after pushing the "on" button.
I wonder if it the gyro for angle sensor spooled up?

Seems like it would be good to know what the sound is....and....what to expect if the sound stops?

You have a point. And my bet is, if the sound stops so does your bike.

My '22 RT does it as well - I've narrowed it down to within the fairing and suspect it has something to do with the auto leveling/adaptive headlights. Maybe some sort of calibration for angle and lean.

When I initially picked the bike up the sales rep had the bikes accessories switched on to show me how to work the electronics. There was no high pitch sound. I am taking it to dealer tomorrow.

Cooling fan on an LED light?

My 2019 RT makes the same noise. Coming from the throttle bodies. Totally normal from what I was told ...They all do that...lol

I didn't hear mine at the dealer either - when I got it home, it was really loud in my garage. Can't explain not hearing it then, unless it's just that ambient noise muffles it. I can barely hear it when I'm outdoors with a helmet on.

Oh yeah - one more thing. When I first heard it, I started the bike, waited a couple minutes and then hit the kill switch and set it back to run. The sound was gone - leading me to believe it's some startup activity.

Yea, it reads at 51 decibels at the battery location and about 32 decibels at the rider.

I went to dealer and the head tech said the sound I am hearing is normal.

It's just the wallet sensor warming up. It determines how much cash/credit you have and picks the worst possible time to activate an expensive service warning.

Yea, I was thinking the same as you.
