just came back from this trip a few weeks ago so know it very well. all good advice from above. now it depends on what month you go and I went a couple months back in july but add the following
1. extra water bottles - all these places will be 30 plus daily and its a hot dry windy run
2. don't ride early dawn or late at night as in qld I saw 1000's of dead roos along the edge and in the centre of the road - you only have to hit one and it could be over.
3. once in nt roos are not the problem and nearer to alice springs/ayres rock
it's either stock/cattle or wild horses which come out from no-where and can cross in front of you. these can range from 20 to 50 plus and scare the shits out of you.
the road to ayres rock is classed as the most dangerous road to drive in the northern territory and more people get killed on it than any other road. main reason tourists/night driving/right hand drive cars/camel/stock/roos -better stay off this road at night.
be prepared to be ripped off heavily on the way too - plus your arrival at ayres rock. they are there only to take as much money as they can get out of you. just one gas station $2.20 litre. the cheapest room was a glorified toilet @ $189 night. next room up $450 night and after that ..sky is the limit now I couldn't even get into the caravan park for even a tent site. it is geared around one thing only money!
back to your trip. coming from qld the road is pretty good to the nt border but as you enter nt the first place is a hole called ranken. unless they improve the road either side of the entry point to the dump be very careful here.
there were huge pothole in the road. not one or two....bloody lots of them. I'd hate to hit one in a car -on a bike a new wheel for sure and maybe on your ass. without doubt the worst bit of road you will encounter on the whole trip. best of all it will only go for a couple of 100 metres either side of the town. with luck they may have them repaired by them. either way keep it in mind.
you will be handicapped though. once the boys see the 130 zone that will excite them and 300 klm out and as they near the alice and hit the open speed limit well ..............bye! I know I flogged the shit out of my car, you have about 70klm first to have a hit. this part is not quite as good but alright and after that a 20 or 30 klm break at legal zoned speed and then a 190 odd klm open run.
best tell them too in between that open speed limit is the restricted speed zones and the radar cops and if you come out of the zone and over the posted speed limit by just a couple of kph -these coppers will book you.
I was told this several times by locals in alice. they wait for you with the radar gun once you exit the unlimited section as its hard to drop from say 200 to 80 or 100. its like you stopped! well maybe not on an enfield...lol
but the trip is worthwhile....especially one section even i think I might do it again. if I do this time I plan to have my car road transported to and from alice and fly over and just get in it - stuff the 7 day drive as it wears you out...lol
