First of been riding since i was 17 TZR125. Now 44 and still love riding.
Knee down - When i first got my R6 back in 99 and had my first set of leathers with knee sliders. Wanted to be able to get my knee down real bad. So didn't stop til i had it.. From there, it was at every opportunity ! dont do it anymore, simply cos i no longer own any leathers with sliders.
Wheelie - Powered wheelie all over the place in, but TBH, never did one of those long controlled stay up for ages wheelies. I wish i could, but don't really bother trying. My FZ09 lifts the front everytime i pull away from the lights hard, but again, i'm not doing anything fancy clutched. Besides i now live in Florida, and well lets just say we never wear the appropriate gear. So in a way that keeps me from hooning around as much.. Not to mention i'm 44 and a little more privy to hurting myself.
Stoppie.. Never done a decent one.. Just too costly too me for it to go wrong. Prolly done a couple on hard braking, not nothing intentional.
Powerslide.. Loads, actually when i'm on my dirt bike, i just love to powerslide.
Tank Slapper - Had some really bad ones on my R6 V1. til i got an ohlins damper. Cant believe Yamaha let the bike out the factory like it.. must have been responsible for many accidents. You'd open that bad boy up, and next thing you know you're in a vicious tank slapper... Actually nearly got thrown off under the dunlop bridge at Donnington, hitting at least 120mph, with the slight bump there.
