Really great trip with lots of good photography.
I need to put my opinion in here regarding the bikes.
I have done van Zyl's on an XT500, XT600E, 690 and 701.
The 500 and 600 both suffer from inadequate ground clearance, especially when loaded for a non-supported trip.
Other factors play a huge role on the bikes, and on the video Noneking posted of PK going up "heartbreak"?, it is very clear that his bike was hopelessly overgeared for this terrain.
This is so important, where guys gear the bike for good open-road cruising, then suffer in the technical areas, and cause major stress on mechanical parts.
Peter Boardman was on a 650DR with us over van Zyl's a few years back, and if your gearing is right, you keep a fair pace with the motor not wanting to stall.
Very true - It makes a huge difference on the XR's if you sprocket up from 45 to 48 and even 49.
The other big mistake that I noticed is the fact that most people opt to try and ride around the rocks on the way up.
This culminates into all sorts of mistakes (target fixation downwards, too much throttle play, too little speed or momentum).
Picking and sticking to your line, allowing the suspension to do it's work, while keeping good constant momentum usually gets the job done.
Very good observation 2SD
