Sometimes, with all the weight, the Rocket doesn't stop too gracefully. It has great brakes, but there is a learning curve on how to handle the thing and bring it down nicely, isn't there.
Every once in awhile I'll get in a situation like you describe and will be a little awkward bringing it to a stop. I've learned to always make full stops, no drifting through stop signs with this bike, it doesn't like panic stops...
