Do not go where the path may lead, go instead where there is no path and leave a trail.

Wow, talk about stacking the odds against you.  That location is 12,000 feet above sea level.  Forced induction is your friend.  I can't believe that salt flat is 100 times larger than Bonneville.

Very interesting video.   I somehow didn't realize the FIM allowed record attempts in the thin air at high altitude.   Bolivia is very enthusiastic about motorsports so I am sure there will be other record days on the Salar.   

And yes, the Salar de Uyuni is huge.   The Dakar Rally has crossed or skirted it for the past several years in Bolivia.    In 2015 they crossed the Salar with water on most of it; plus they did mass starts (for the television coverage).    The pictures of that day's stage are pretty spectacular, but the salt ruined the electrical systems on quite a few of the bikes, especially the factory Hondas.   

If you are there as a tourist, there is a business at the edge of the Salar which will coat the bottom of your bike or car with diesel fuel (oil) to help minimize the corrosion.

If you're interested in learning more, Mark Gardiner wrote a couple of stories about these attempts, covering just about everyone who went:

The thin air at that altitude poses no problem for the turbocharged motors used in virtually all streamliners and it causes less drag.


I would not have expected turbo's to overcome "packing in the air molecules to the motor" with the lower density. If they do - with lower density air for the vehicle to pass throug - I can see land speed numbers higher than at Bonneville.


Yes, nice reads - thanks!

Turbo tuners will up the boost at elevation.  If they were to take the same tune (boost level) to the SoCal dry lakes, they'd probably blow the motor into many small oily pieces.
Call me Mel. Some years ago- never mind how long precisely- having little or no money in my purse, and nothing particular to interest me at home, I thought I would ride about a little and see the other parts of the world. It is a way I have of driving off the spleen and regulating the circulation.

I just got around to watching this. I really enjoyed watching this and it's good to see folks chasing dreams, especially on 2 wheels. Thanks for posting.
