I’ve bought… ahem, a few new bikes over the last 10 years or so, all BMW, all from the same dealer, and since Datatag has been factory fit as part of the Master scheme I’ve always had an email from Datatag a day or two before picking up the bike. The only time it hasn’t happened is with used bikes, but then it’s down to you to contact them to do the transfer (or arrange it with the seller if it’s a private sale). I think it’s about £20 in this case.
