I've put 6000 Adventure miles on my 2023 KTM 890 Adventure R and we are still having some ups and downs. See check engine light always coming on...
Things are getting better however, I did manage to end the Antenna Immobilizer issue/fault and got some knobbies installed for my trip round the ORBDR.
I'll also talk about the mods I have made thus far.

Things on the 890:
DualVenture front tire
Rallz rear tire
MSC Moto steering stabilizer
Upshift Online No Bull graphics
Barkbuster VPS Handguards
AXP Skid Plate
Vanacshe GPS mount
Vanasche side stand delete
Rottweiler Performance air box
Rottweiler Performance brake master cylinder guard
Rottweiler Performance evap canister delete
Rottweiler Performance fuel hose and pump guard
Cheap Chinese control levers
Doubletake ADV Mirrors
Anti Gravity Lithium Ion Battery
Camel Clutch lever extender
