What a pleasure reading this RR
We did that D707 about a month after you guys, hit that sand at around 90km/h and just kept that speed, saved us from falling.
I could never have done that sand sitting on the bike, standing up just make it so much less difficult.
Thanks for the video of that sand stretch, my Gopro was switched off when I hit the sand.
I have tried my best explaining to people about that sand, now I can show them thanks to your video.
Thanks again.
