if you want warranty then get it from martin asap.
if you dont mind voiding the warranty then get it from Germany and save a few quid.
the point is its not fair on ktm and 99.9% of all other uk dealers that wont sell dongles let alone fit them as it voids the bosch warranty.
tho can they prove it ? no answer from any 1 on that 1 tho if you take out the batt so the system has no power at all there will be nothing there like a pc bios.
and tbh u will not need a dongle on that bike going down hill, u need a fkn force field
