supposed to be pothole riddled
I'm not sure where you heard that, but I have never seen a single pothole on the 'Ring.
I've done a fair few laps in my life, been 3 times (2 times in a car and went last year on a bike) and i'm going again in 2 weeks on the 675.
I'm not going lie, it's **** scary to start with. Last year was my first year there on a bike and it's a whole different animal. Corners obviously come at you quicker and the lines are different, not to mention the common as muck 911's and M3's that are forever trying to squeeze past.
The thing I have always said about the Nurburgring is the faster you go, the safer you are. If you can keep pace with most of the traffic (there will ALWAYS be someone faster than you) then you will usually have a good lap. If you're pootling around that is fine but be prepared to spend more time looking in your mirrors than straight ahead.
I've done a lot of the UK tracks and the ring is like none of them, you have to have the up-most respect for it, or it will bite you. One of our group threw his 2 week old Panigale S at the armco last year....
The best advice I can give anyone going for the first time is go on a day / week when the track is open in the evenings, on weekend it is like the M25 most days... in the evenings (usually opens around 17:00) it's very quiet and great for learning the track.
Hope this helps, as I say I'm off there again in 2 weeks and will have my GoPro 3 (filming not allowed.. btw, but if you're cheeky you can pull over after you go through the barrier and set the camera up) and I will also get some more pics
Enjoy it mate.
