Which bike to buy?! Lima, Peru and beyond

[fluidmovement02]

I have a decision to make here in Lima on what out of two bikes will be the best for touring around s america. Limited on money so my options here are a couple chinese bikes, wanxin and RTM both 200cc. Small i know but heh better than nothing. The Wanxin WX200gy-a is very basic, its considered an enduro but is kinda a classic road bike that could be taken off road just not rallyed too hard. Its got a semi wide flat seat, sits pretty low, 12hp, gets about 88mpg and i think it has a 2 gallon tank. Its also got a rack on the back. Brand new for $1100 (can probably get for less). The other option is the bit more flashy RTM 200 gy which is a really nice looking full on enduro with racks on front and back and a very molded angled seat. Its got 15hp, 2 gallon tank, and gets 74 mpg. Cost pretty much about the same. I keep going back and forth on which one would be better, I really like the KTM but wondering if the other would be more comfortable and more inconspicuous. Anybody got any tips? oh and i want to be driving through the mountains but will be forced i think at times to drive on highways. Both could handle i think. Thanks ciao
