Really practice braking...as if it really matters.
A story from the ride home last night...
I'm cruising along at about 55MPH on a fairly smooth-flowing but tighly packed freeway when it has one of those "everybody hit the brakes" moments which are the most dangerous times to be on a freeway (I've been in cars that got crunched in those moments...not fun). So I start to brake and am thinking of slipping into the space between lanes to my left and filtering along when I get startled by this front fender in front of me... some asshat to the right has decided to do a plunge-merge into my lane, not knowing (or caring) that I'm using it. Then I do a really dumb thing... I lock my rear wheel. It slides out to the right, nearly hitting the asshat's door, but I countersteer (the real countersteering, not this namby-pamby "push steering") to keep tracking and then start feathering the brake and adding power... I almost get it back together and like a dumbazz I swing the tail out to the left, still swiveling the front around to keep going more or less a sane direction... at this point I'm skidding along between the lanes to the left of where I started... btw: highway dots make nasty thumping sounds when you hit them with the sides of your tires ... I finally get it almost settled, fishtailing to the right a bit but not bad, but I'm overbalanced a bit and I'm in danger of tipping the bike over to the right (a technical highside) so I do a final dumb thing and use my right foot to stabilize the situation...kick the ground to set it (or perhaps me) more upright. At 25-30 MPH the ground kicks back BTW... and then I'm I'm coasting along between lanes with the engine lugging because I never downshifted, my right toe hurting a bit but nothing too bad... so clutch clunk clunk and add some gas and roll along. I didn't bother to stop since nothing was really harmed and, had the asshat also stopped, I would've been hard pressed to maintain a civil demeanor.
There are several lessons: don't be a dumbfuk with your rear brake; start filtering early so you won't be trapped in traffic and forced to combine braking and maneuvering; wear your $&#*ing boots (I really like my Alpinestars...bet I'll like them more if I pull another dumb stunt like this

); don't give up the bike (I identified and avoided three ways of dumping the bike over the course of that 4.7 second event); and practice your braking some more so when you have your moment of surprise you don't lock up and go down.
Finally, practice in different ways. I've done parking lot hard braking practice many times, and in the last two months or so (I've been riding about three) I haven't locked the rear up once while practicing on dry pavement... but obviously I wasn't practicing correctly becaue I managed to do it yesterday. OTOH, I've also practiced riding my ninja on dirt roads and the like, which is IMO why I didn't dump the bike.
Oh, and Bombay Saphire makes a better martini than Tanqueray 10 no matter what anyone says.

Ride it like you think owning it matters.
