I was cruisin, last sunday, and at a certain point the spyder shifted down from 6 to 5, while I was running at 2400 rpm's, upshift wasn't possible, shifted right back to 5th gear.
Stopped, and looked if I could see or find somthing out of order, nothing wrong. Hopped back on, and the spyder was running as usual.

Yesterday same problem, anyone any suggestions, spyder had an oilchange and filters a few weeks ago, I checked all the fluidlevels, and they are right on the money.
So I am a bit flabbergasted...
The ryde is a Spyder F3s 2019, with 12000 km's on it

Thanks in advance
