You can stay as long as you like on your EU nationality, rather than passports. However, I think you may complicate matters for yourselves with the actual physical lack of an exit stamp on your Canadian passports.

I also have dual nationality, but I have always entered (and been stamped in) as a certain nationality and been stamped out in the same passport so as to avoid some officious border pr1k having a reason to hassle me to over why I was stamped into a country,but not out.

Very easy to solve though, exit the EU i on your Canadian passport and then enter Montenegro/Serbia/BiH on your UK/Cro passports. Just turn around and reenter Croatia then using your EU passport and all potential future problems are averted. You basically swap nationalities in no mans land.

Be wary of EU border crossings (entry from non-EU countries) they like everything to be 'just so' and can in my experience be utterly painful to deal with.

Registering Canadian bikes onto EU plates may be easier or harder depending on the year, make and model and the country you are in. If you want to go that road, you will need an address and be prepared potentially for some eye watering import duties (varies by country) and hassle as regards getting the vehicles 'inspected'. The EU is legendary as a dual buerocracy, each country has its own ludicrous hoops to jump through as well as a second set created by the diktat of Brussels! You will soon discover why it is very hard to do anything of a business nature in the glorious fatherland........

Sorry EU. :st ormy:

Not an issue in the UK as you do not get stamped out of the UK, regardless of passport.

Just a 'head's up' for you on a slightly different but very closely related matter:

As long as your bikes have Canadian plates on them, DO NOT allow anyone else to ride them while they are in the EC. Doing so puts you at risk of having import taxes imposed on the bike immediately, along with a corresponding penalty.

I learned this the hard way a few years ago. I had my Canadian-plated bike in Germany, and loaned it to a good friend (Austrian citizen, EC resident) for two days. He was stopped by German police in a routine traffic check, and the police determined that by the very fact that he (not I, the tourist) was operating a vehicle that had not been properly imported into the EC, full import duty and taxes were due on the bike, as well as a penalty amounting to 100% of the duty and taxes. The whole bill added up to well over €2,000.

Hence my advice to not let anyone else ride your motorcycles until you get the Canadian plates off and the local (European) plates on.

I also suggest you be very careful about doing anything that implies establishing your residency in the EC without simultaneously getting the bikes plated in the EC. In other words, if it appears you are resident in the EC, rather than a bona fide tourist in the EC, you could get nailed for not properly importing the bikes, as they would no longer be considered as 'tourist vehicles temporarily imported for pleasure purposes'.

In the context of the above paragraph, there could be certain advantages to you having entered the EC on your Canadian passports (rather than EC passports). As you pointed out, citizenship does not equal residency, but the whole matter is a lot 'cleaner' if you are 'all-Canadian' on the transaction.
