Having just seen Iguassu you may be over dosed by waterfalls. I haven't been there, but have read about a crazy long water fall south of Iguassu, called Salto do Yucumã. The edge of the waterfall runs almost parallel to the river, making for a very long waterfall. Not as dramatic as Iguassu, but very unique.

Here is what it looks like:

Few people mention it and its hard to find a website in English that describes it. I suspect it is not a greatly developed tourist site. Here is the Wikipedia page in Spanish that you'll have to run through a translation, ex Google Translate or just use Google Chrome and it will translate on the fly, when it works...

Salto do Yucumã – Wikipédia, a enciclopédia livre

Its ~214 km south of Iguassu, a solid days ride as I am guessing the roads are not highway grade.

General thoughts:

I loved Argentina, but would recommend not going to Patagonia in March. It will be getting into the cold season, in a place where it can snow in summer (December/January.) Its ~1500 miles from BA to TdF, and ~1500 miles back. That is like riding from NYC to LA, on mostly long boring roads, a little excitement, then more long boring roads. I'm going to get in trouble with those that loved the trip, so I'll stop here.

Are you planning to visit Brasília? It is not a pedestrian friendly town as the buildings are spread out, making walking from one place to another difficult. You, on the other hand, have a motorcycle. I wanted to go there to check out the architecture, but my schedule wouldd not allow it...

If you make it to Bahia, there is a cool little beach town just south of Pôrto Seguro, called Arraial D'Ajuda. I recommend it. Pôrto Seguro is more commercial, not as hip.

Wish I could recommend some rippin roads, but sadly I was covering lots of ground running the length of the country. I stopped for several days in Recife, then south of Salvador in a little town called Itacaré, then a few days in Rio while the BMW dealer wasted my time for a few days...

The roads are out there. Sometimes Brazilians jump in and start making suggestions...

Another tip, sign up for Couchsurfing.com if you haven't already. Brazil was the most welcoming country for me. I was invited to stay with people right and left. Mention your adventure and post an itinerary a few days out to cities where you are headed. It a great way to meet local and get an insiders tour.
