buy a bike
 

I greet you, friends. I am writing to you because I am asking for your help and advice.
I am planning a trip around the world on a motorcycle, I will go through Europe and Asia on my bike, but then I will fly to the USA specifically to Seattle at the end of May and I want to buy a motorcycle here and travel around the USA and then sell it again, and I do not know the local customs, so please advise where buy a bike? best k1200lt website? is registration a big problem and how is it done? is it safe to buy a bike remotely now? thank you for the information and have a nice day.
