I have the 658 BMW which of course would be compared to the 19/17" Tiger 800.
With the claimed weight of 377 for the 658 and the under seat fuel tank, I think the 658 is pretty nimble for its size/weight.
With the standard location tank, up on top like most all bikes, it seems to me the Tiger 800/XC will feel more top heavy.
Not that the Tiger is top heavy really, but as compared to a bike whos fuel weight is not carried up top.
Merely pulling the bike off the kickstand could feel heavier with a full tank located on top.
Just my observation from those here who feel the Triumph is top heavy...
It will be good to see a comparo between the 658 and the more street biased Tiger 800 ...in time I suppose.
