Un Capuchino por favor!!!!
As a local here, maybe I can help you. Also I love the Cafe Racers, I’m making one with my old Gilera 200c.c. and use to take it to travel a lot (many years a go). But….
From BA to TdF most of the way is tarmac, only few dozens of miles are “Ripio”.
“Ripio” it’s a kind of gravel but in a shape than you never saw. From TdF to the North ( the famous R40) is most ripio and mix with wind but also very strong winds….
I will pay to see you riding on 17” wheels and clip-on handle bars on the Ripio…
Also you can find a lot of common gravel, mud and potholes if you leave the principals roads.
Stopping off at plenty of cafes …. Yes, but if you find where after many hundreds kilometres.
Any way, is your decision many travellers do it on a bikes than you will never imagine. Some do it on CT200 Farm bikes, R1, C-50, Monkey bikes, Harleys, Jawas, CG125, and a lot more. My wife ride a SR250 Special fitted whit trail tires and take a lot of gravels and ripio roads. Also Jeffrey from Cusco- Peru (Norton Rats Tavern) made TdF on a Norton Commando contact him by his website to ask http://www.nortonrats.com/
In your shoes I will go for a trail even a Serow, but anyway you and your Goose are welcome here.
Hope to meet you.
