Hola,
here in south America the Bajaj does not come with FI.
You have a fuel range of 500/550km on 1 tank.
Just make a strong rack for luggage.
The motor is good and has 22hp.Japanese bikes have better suspension,
but they always cost a lot more.
A second hand Honda Tornado cost about 2800dollar or more (in Ecuador)
(new 6400dollar)
A new xr125l about 3200dollar,but has a lot less power.
But i have seen people (not to big) 2up traveling on them,slow, but good suspension.
So if you are on a budget the Bajaj is really not a bad choice.
Always if you want better, just pay more $$$.
When you are traveling to South America ,just go to a shop
and see how you 2 are fitting on different bikes before making your choice.
Good luck!!
