This is a serious post correct? 1st, why are you overly concerned with dragging knee? Just to say you did it? No one really cares if you do or don't, well I would guess you, but that's about it. 2nd, doing it on the street in leathers, seriously? If you are in Cbus, there are only a few roads that have even a decent setting to do this safely, and even then, I would doubt they are "safe" by normal standards. 3rd, you state you need new tires and brakes as it is... The last thing I would do needing tires is be anywhere concerned with hitting the knee slider, that is just a high side or low side waiting to happen, I've done both, on the track, ain't fun or cheap. I am not trying to be a dick here, but trying to be realistic. I've seen plenty of people drag through hocking, and comparing something like that to the track as far as if you do lose the rear, or start a tank slap with oncoming traffic, just isn't even partially smart. I tried in my hayday too so I am guilty, but once I realized after seeing 4 wrecks in 1 hocking ride, some from people grinding the puck, it just isn't smart. Save up, get your tires and brakes, then hit a few track days. If you hit knee great, if not, again, who cares? I know some fast riders personally, that have never hit the ground either, and still have some great riding abilities. And as stated, it will come naturally, the first time I ground tow I was scared in the Esses at Mid O like wtf, the first time I ground knee I about crapped, but it was just randomly, different sessions, different days. Then I ground both knees and my bike as well from a wipeout and it blew. It doesn't always help improve turning either, but it can in the right enviroment (track) since you aren't setting any lap times on 270 dragging knee.
