This is of course good advice, but they're called survival reactions for a reason - anyone who gets surprised and/or shocked by the bike suddenly doing things you're not expecting will be doing things before there is really time to start analyzing what's going on, ie reacting. Which is why I said the only way to have the right reactions to control a slide is to create those reactions through endless repetition. Which may not be practical and certainly not entirely safe to acquire on a normal bike. There are sliding rigs designed to keep the bike from tipping over out there for some bikes but you'd probably have to custom make them for the Rocket, and it's all increasingly unlikely to make sense/happen.
One of the problems of humans driving anything is the fact that humans are incredibly slow and inept. Including me, not saying I'm exempt - it takes us literally at least a second, more likely two, to process what is going on and start making intelligent decisions. Two seconds in a situation where the bike's rear suddenly steps out on you is an age. Pre-trained reactions is the only thing that may keep you in the saddle - well that or pure luck. Check out how fast things happen in this video for instance, it's a bunch of high-sides where the rider made it. From start to finish of the incident is easily under a second; the rider didn't have any time to think about what was going on, what the riders did was pure reaction possibly aided by training. Not all highside situations end badly, but there literally isn't time to be either calm or scared - the situation begins and ends before any really reasoned thought of any kind can take place.
