You should read Rocinates Travels report on a Tiger through North and South America. They did have a few troubles...
There is a link to their site on the Links page, and in many newsletters.
Generally conssidered to be a pretty good bike, but heavy, especially top-heavy, mostly reliable and solid.
If the "off-road" is merely an occasional gravel road, there shouldn't be any trouble. Pay special attention to keep the weight well down, don't use a big tank bag etc.
Should be fine otherwise.
