Well don't know for sure what broke the camel's back on each of the two Team Honda Honda Talons. Here is what I could see from live tracking.
T903 - Elliot Watson made it to MM33 and stopped, after about 3.5 hours was trailered down I-15 back to main pits. Never continued. Don't know what happened yet.
T940 - Christopher Polvoorde made it to MM 40, had snapped right front shock, got repairs and in about 2 hours continued to MM105 at the main pits where an axle was replaced according to a live interview in pits during axle swap. Completed lap 1 at 5 hours 11 minutes. Stopped progress in lap 2 within minutes, returned to main pits. Don't know what happened to him after that.
With 2 hours left in the race, by 7:54PM PST both machines were sitting in parking lot away from event and main pits.
Top machines were completing the 107 mile laps in just over 2 hours each. Difference between 1st and 5th place was about 35 minutes for 4 laps 428 miles. Here is the list of laps completed and times, NOT listed in order of finishing. Brandon Sims T913 finished 1st in 8:27.
