I looked at the 800XC as a possible replacement for my 09 F8GS, but left the dealer wondering where he went wrong!!
I loved the 800XCs engine, for a road bike its brilliant, but the rest of the Triumph lost out.
In my opinion, the Triumph is cheap in build, has a lot of 'wrong' materials on it that will not stand up to constant off-road use, and here in Oz, it has to be optioned up to the same standard spec as the 800GS, which makes it virtually the same price, within $100, and the serviceing costs are higher with the 800XC, which according to the salesperson is because its got 3 cylinders??
Triumph started with a clean sheet of paper, had 3 years to develop their bike, and barely matched the BMW let alone bettered it!!
I think the 800GS is a more robust bike and proven its still the best 800cc Advbike on the market.
