Can I hire a bike from Sao Paolo to Rio?
 

Hi guys, anyone know if I can get from Sao Paolo to Rio on 2 wheels? Just 1 way! I just prefer going by bike, don't care if it's a 125 or a 1400...

It looks easy enough if you've got a bike license. Let me Google that for you:

A day or so on a Harley sounds good to me if a tad expensive.

Yeap...quite easy. Is you want biggger bikes you have the BMWs, Kawasaki's and Harley's. I do that route every week-end on my KTM 990R (live in Rio but family is in Sao Paulo). Try:

www.trailtrip.com.br(Kawasaki)
www.roadexperience.com.br(Harley)
I recommend a 120km/h plus bike due to traffic. You do not want to be much slower that it. If you're travelling on a week-end I can guide you and show some sites.
Cheers, George
