Got my Vitpilen 250 on Feb 14, 2026 (new 13.5L tank model). 2500ish km on the odo.

Issue 1 — Stalling during downshifts (main concern)

Happens at low speeds, usually under 30-40 km/h, only during downshifts. The sequence:

1. I pull the clutch in
2. Blip the throttle (small rev, maybe 1.5 sec)
3. Fully release the throttle
4. Try to rev again to downshift smoothly — and get no power, like the throttle is dead for a brief moment
5. Rev again — earlier it used to recover and power would come back normally
6. But recently, instead of recovering, I hear a metallic click / clang sound (sounds mechanical — something like if the tyre goes on something and it pops. The issue isn't related to the tyre, I just wasn't able to come up with a way to describe the sound — that's the best I can describe it. More like something popped or hit something.)
7. Engine just dies
8. Have to hit self-start to get it going again

So earlier it was only the throttle dead-spot in step 4 and it would always recover. Now it's started actually stalling with that metallic click.

Issue 2 — 2nd gear hiccup (happened twice)

In 2nd gear, when I accelerate hard around 5-6k RPM, the bike hiccups violently — literally pushes me onto the fuel tank and then pulls me back. Like a sudden jerk forward and then a sudden pull back. Happened twice now.

Issue 3 — Quickshifter weirdness at high speed

When using the quickshifter at high speeds, going from 5th to 6th (around 90 km/h), I just tap the gear shifter (not pressing hard — not sure if that's the issue). The bike briefly revs up, kinda screams, half-goes into 6th and comes back to 5th. Whole thing happens in maybe under 2 seconds. Is this me not using the quickshifter properly, or is something wrong?

Anyone else faced any of these? Known issues on the 250 Duke / Vitpilen platform? What did your service center do? Should I be worried or does it sort itself out with running-in?

Thanks 🙏
