"Citizenship?"
"What's the purpose of your visit?"
"Where ya going?"
"How long you staying?"
"Are you visiting anyone while you are here?"
"Have a nice day.'

The border guys couldn't care less about how your bike is financed.
Don't say or do anything stupid.
If they ask if you've ever smoked pot, lie and say 'no'.

The above is pretty much all I've ever been asked, but I've only crossed that border 4 or 5 times in last 20 years.

One time the guy did ask if I had any guns ... NO is the answer, then he came out to look closer at my bike. He rode a BMW sport touring bike, IIRC.

AFAIK, ALL US insurance companies cover you while riding in Canada, NO special permissions required. Watch out for the very LOW speed limits in Canada ... and due to having almost NO crime of any kind, the RCMP (coppers)
are hiding everywhere with Radar guns.

When I was last there, Foreigners PAY ON THE SPOT for tickets (unless this has changed?) I paid twice crossing Canada years ago. Ridiculous low limits ... In the USA cops typically give tourists and foreigners a break ... NOT SO in Canada. (can't blame them!)

You may face far more scrutiny re-entering the USA. Our Homeland guys often about 20 IQ points below the Canadians in terms of basic instincts and common sense. Military absurdity all the way.

Riding a dirty bike that's been on the road a couple months, I was treated like a criminal ... just trying to cross back into USA.

This was at height of 9-11 hysteria ... but no excuse, IMO.
Horrendous behavior. I can only hope things are more sensible now.
