Hi I just wonder if there are any unpaved road in the uk like the picīc attach in link http://www.myra.nu/grusvagar.html http://www.spjutaretorp.net/slingrig.jpg and where are thy any close to London or do i have to move to Wales

The reason I ask is that I am trying to make up my mine about my next bike a 990 adv S or a 950 Superenduro.
I had a 950n SMR before and loved it and after a short time on a sport bike i want to go back to a KTM but one that's able to go off the sealed roads and do a bit off green leaning but still be a good day to day bike for comuting in London.
I will also tour with it and I know that the SE only have 14l but so did my SMR and i whet to spain and back without any problem.
