Motorcycle to transport trailers?!

Hello dear community me once again a question is burning under the hood. And I am just changing and would like to transport my bike on a trailer. My neighbour can possibly borrow one, but the one has no track where you can push the bike in. So it is a “naked” trailer and I would have to secure my bike alone with clamping straps. How do you do that?? With such a track I can imagine that, since the front wheel has a quite fixed position, but if there is nothing at all, I wonder how this should go. Would be happy if you could give me some tips. Short to the road: 250km, 90% highway Thank you very much!!
