EDIT: So far this appears to be a one time occurrence.
I have read about other RX3 stalling problems, and hoped it would be fixed by now.
It is not.
On my first 50 mile ride, I had to make a quick stop for a traffic light.
Let off the throttle and applied the brakes hard.
I stopped in time for the light, but the engine stalled.
The engine restarted after 3 or 4 cranks.
When the light changed, I started off, but the bike stalled again...in the middle of the intersection.
It would not quickly restart, and I had to push the bike through the intersection (with cars zooming around me) and to the side of the road.
The engine finally started after another 3-4 cranks.
There were no further incidents the rest of the trip.
This would not be a problem out on a trail....
...but in traffic, this could have gotten me killed.
None of my other, or previous bikes, have done this.
Hope there is not another occurrence.
