They will just extend your current warranty by the amount of time you didn't have access to your bike.
Mine was down for about a month for the dealer to replace the battery, son they added a month to my original warranty.
In your profile in Stark's site, in the vehicles section or in the Varg app in that section that shows information like suspension setting and rear rim size.
Re: Warranty. I need to look into this further... but it seems that for bikes sold in Spain, the warranty starts from first registration and legally has to be for 3 years (as of road vehicles sold since 2022).
