I owned about 80 bikes. This bike will be riden solo only. I'll test ride both bikes shortly, but only on pavement. I lean to the Sertao for cost, styling (Tiger looks fairly ugly to me in images only), and perceived better off-road manners. Please don't comment about styling unless the Tiger looks better in person than in images. Off-road I presume there is no way the Tiger can overcome its extra 50 lbs. Comments welcome, especially if you rode both exact models specified, and even more so if you rode them both off-road. What, if any, earlier BMW model year has similar mechanical specs vs. the Sertao? What, if any, mods exist to coax a little more power out of the Sertao? Thanks!
