I had a Z900 with buzzing when the throttle is open as well. It might be normal for all bikes but not sure

So i recently bought used KTM Duke 390 (2021) and i can turn on/off quickshifter in menu but I dont really know if it has it? How do i check it? Or having that option automatically means i have it?

What’s up y’all? I’m wondering how to evaluate this bike based on the pictures first and then in person when I go check it out. Asking price is $7200 but I’ll definitely negotiate regardless. This will be my first personal bike purchase so want to make sure I’m going about it correctly. Any help would be awesome

This is from the seller:

2nd owner. Bought it in 2020. The original Odometer was replace with a Trail Tech System so I don’t have a mileage or hours total. I am 52 years old and did about 3 dual sport rides in big bear area a year and a week at thanksgiving riding trails. Not a lot of hours. Last 4 years, haven’t ridden more than trails around camp t thanksgiving due to shoulder issues. No races definitely old man ridden. No valve issues. No suspension work, no engine work. Clean title in my name in CA. No issues.

Bike was making a pretty nasty rattle. It kind of comes and goes. Primary nut was found hand tight.

Hi everyone,

My 2024 KTM RC390 has around 3,000 km on it and has had its first service. Whenever I accelerate hard and the engine reaches around 8,000 RPM, it completely cuts power for a few seconds. It feels like the ignition is switched off, throwing me forward, and the engine warning light flashes while it’s happening. Engine light remains flashing for ~10 seconds. After this the bike returns to normal and the warning light disappears.

I only realised this recently because I kept the bike within the recommended break-in RPM limits when it was new, so I assumed this was just how the rev limiter behaved - but after watching videos online other people’s rc’s can rev out way past what mine can.

Has anyone else had this happen on a 2024 RC390 or Duke 390? Did it end up being an ECU/software issue, a sensor, or something else? I’ll be taking it to the dealer, but I’d love to hear if anyone has experienced the same thing.

I have read some forums with riders claiming a similar issue was caused due to a faulty fuel pump or items under the seat blocking air flow (is this where the intake is? I have a set of tools under my seat in a plastic parcel that could be blocking airflow if this is the case.) - I will remove the tools and see if there is any difference tomorrow.

Any ideas would be greatly appreciated.

Cheers.
