Yes, I have ridden heavy bikes. I have also ridden medium bikes and light bikes. Thumpers, twins, 4-bangers, sports bikes, standards and cruisers, on and off road. Trust me, I know the difference.
I also know that if you brake hard, and do it correctly, the back end will not come around. That is unless you brake using the rear brake only, in which case you should not be allowed on a bike ever again until you learn proper braking technique. And of course you should only ever brake hard in a completely straight line. That's pretty basic stuff.
In ideal hard braking on a motorcycle, the rear wheel should just barely be on the ground. That means you're putting the maximum amount of braking through the front wheel. Of course, some bikes are so damn pig-heavy, long-wheelbased and underbraked that they can't do this, so adjust accordingly. The point is that you have to put as much braking force through the front wheel as possible. Again, basic physics that everyone who rides should know.
Yes, of course you shouldn't be off the gas when swerving, but you shouldn't be accelerating, either. Neutral throttle, learn it, live it.
Your overconfidence is still showing.
