The first change is the addition of a new chicane between turns 3-4. This should slow bikes down in the surprisingly high-speed esses which lead to a tricky, slippery and dangerous uphill turn 5.

The second, and most controvertial, change is an entirely new pit-in, turn 12 complex which completely bypasses the ultra high-speed downhill old turn 12. It also bypasses the big concrete wall at the exit to old turn 12 which nearly took the life of Miguel Duhamel in a testing crash last fall.
Only time will tell how these changes will affect bike racing at RA. Safety is always a good thing and these changes will surely slow the bikes but may introduce more dangers of their own. At least they will be slower speed dangers.
