The speed is breathtaking (for me at least

1. Don't have your speakers too lound to start with or do depending on your desire to hear a bike running around 10k rpms
2. If you are prone to motion sickness you may not want to watch it in full screen, or take some dramamine first.

3. When the direction of the camera seems to point upwards the bike is either doing a wheelie, or completly off the ground and comming to a landing. Which in its self isn't amazing, untill you see the speed he is traveling.
4. Note the TOTAL lack of any protective barriers. Amazing in this age of safty this race is still going strong.
