In general, we would advise against it. Let me just reproduce this answer from our website FAQ:
We have a vertical integration approach towards your ownership experience. Which means we don’t just sell a scooter to you but ensure that every aspect of your ownership journey, from purchase to after-sales is hassle-free. We do this with the help of a dedicated customer service team which is currently present only in Bengaluru. That’s why we strongly discourage purchasing the 450 and taking it to any other city, as we will not be able to take care of your purchase, servicing and the other aspects of after sales experience in that case.
Kerala is definitely on the cards, just not in the next 6-7 months. We would definitely advice your friend to wait
