Old thread, but might be useful to update this with how it went for future reading.
I managed to get it all sorted. I insured for the remaining 2 months with MCE. They gave me the best offer for a full year, which I paid upfront. Then I called them to cancel on the day I had it exported and all it took was 5 minutes on the phone. I had the balance returned to my debit card in a week or so. Everything went as expected.
I got the headlight unit changed and that was necessary, because during the vehicle approval check by the Dutch DVLA they did check the light pattern! Otherwise it might not have been allowed. Besides that, the check mainly consists of checking it's not stolen, because the model type is already approved in Europe. Interestingly enough, Netherlands doesn't have MOT for motorcycles
I guess most sane people don't ride wrecks..
After the check and filing paperwork, I received my vehicle registration certificate in 8 days in the post and had my plate made. I didn't realise that only a few shops in the country are able to do this on the spot, so managed to have this done 5 minutes before closing time! I wanted to do a trip the next day to Berlin and otherwise I had to wait until after Easter. Luckily insurance here is super easy compared to UK. No hassle online cover and no insane quotes. They even accepted my UK NCB years.
So if anyone needs to go through this, it's quite easy to go through, just reserve enough time for it. My schedule was a bit tight.
So the Dutch Wee is ready for Eurotripping!
