Mattus, the problem with "Adventure riding" in the UK is that Englands greenlanes are are hit and miss as to whether they are good for large adv bikes.
a lot of fun can be had with taking big bikes offroad but you really can find yourself in deep shit quite quickly.
If your going to go offroad then you need to be sure that you can legally ride that lane and a TRO hasn't been slapped on it....don't expect a sign though one should be there.
Many walkers despise motorcycles and are quite happy to let you know it whether their vitriol is legally correct or not.
Its really not a good idea to greenlane a big adv bike on your own because of the weight, though many do.
Some have found the F800 to be quite top heavy for offroad use, but I suppose it depends a lot on the rider.
However, much fun can be riding a good distance to go and ride some lanes then ride back. From castleford the north yorks moors are a good playground.
Wales offers a great playground for greenlanes, for this purpose the big adv bikes are ideal as you can ride a good few hours to an area ride around all day then ride home in comfort. No messing about with vans and trailers.
There is not a lot of off road related activity on here...most of waffle is along the lines of whether this or that widget is better in pink or pink and yellow stripes and I'd wager the vast majority of GS owners on here have road tyres fitted and the closest their bikes get to mud is from the nearest puddle which they didn't manage to avoid.
The F800 is very capable more so than its bigger brother, but I'd rather have the cylinder poking out, it makes it easier to pick up on your own. Downside is deep ruts are a problem.
Just ignore anyone telling you your insane and its too big and heavy for offroad use...yatter yatter yatter..
"Adventure riding" is not something you can really do in the UK as there is no free space, it used to be called touring or Long Distance Trials....but over on the continent those places do still exist.
This whole adventure riding thing is all bollocks to be honest. Its just a big money making scam for all the manufacturers and magazines and shit. Buy bike, go ride bike, choose gear that works properly for you forget all the paraphernalia which goes with the tag. There is some good quality gear which makes things a bit easier.
In my experience, offroading big bikes comes with the expectation that you'll hit some obstacles that you have to lug the bike over/through, that's why its better done in a group to share the load. The fun comes from mucking in together to get past what ever it is helping each other out.
