Hi Ubba,
4 starters... Whe use the term Enduro specificly in case of a offroad race.. if its not a race, whe call it offroad riding. Just so you know, and people don't get confused.

Offroadriding is legal in The Netherlands as long as you don't ride closed of track/roads.
The clue is in the sign at the start of the track/road:
http://www.maniacsmedia.nl/chevreto/image/u36TThis green sign is telling us it is private property, opened to the public. entry only on foot, don't go off the track, put a leasch on dogs etc.. no vehicles allowed.
http://www.maniacsmedia.nl/chevreto/image/uhiuno explanation necessary..
http://www.maniacsmedia.nl/chevreto/image/u9mWclosed for all motorised vehicles on two wheels or more, except mopeds/small scooters (50cc engine)
http://www.maniacsmedia.nl/chevreto/image/uCvNYou are entering state forrest area. Only enter on foot or bicycle. No motorized entry!
http://www.maniacsmedia.nl/chevreto/image/uVCqThis sign may give some confusion to other road users. The official explanation for this sign is: closes to all motorized vehicles on three wheels ore more. So.. motorbikes are welkome! Not all Dutch people know this, and will sometimes lead to discussion. Especially because this sign is mostly used to keep traffic away from rural area's. mostly after complaints from people ho live in that area and don't like traffic. You probably will irritate the hardliners there.. but! its legal on your bike..

For an not dutch speaking person all the different signs are hard to read. Sometimes the green and orange signs say that motorized traffic IS allowed, but only on the wide tracks.
Tip to you. send a PM to the organizer of brabo600. His team organizes offroad riding in Brabant and is allways willing to give some ride tips and training.
