XL / DR / NX / XT Comfort and MPG: what's your experience?

[Warthog]

So I posted in "which bike" to get some views from folks.

My criteria were comfort (kindness to my back: it's a mess), reliability, off-road ability etc.



My shortlist is basically the usual suspects (in no particular order). They are all reliable, all can carry pillions and luggage, can handle some dirt and can be bought from about €1750:

1. Transalp
2. Dominator
3. DR 650
4. XT 600

Have you owned, or better still, travelled with one of these?

If so:

1. Did you have any comfort issues?
(back, hips, @rse, wrists....anything you feel is note worthy)

2. What was you best typical MPG and under what conditions
(e.g. my XR can do 75 mpg, but only about about 70-80 kmph and with Super Moto gearing)

Input gratefully received.
