I don't even know what gymkhana is and after reading this thread, I already don't like it. What works best for me, fat boy on a 1000 lb GoldWing, is to slow down to get to the turn, doing the outside inside outside, and using controlled roll-on of the throttle during the turn. Not too much throttle and not too little. Slow is fast (and controlled). Watching where you want to go really changed my entire method of riding. Before that, all those years of riding was just more and more practice of bad technique. I LIKE riding the twisties and just the above simple little methods have greatly improved my traction, control of the bike, and overall fun. Now, if stuff jumps out of the woods in your line while you're in the curve, then yeah, you have to call on those (superhuman?) skills or crash into a moose and make him angry. Or into an 18-wheeler and make yourself dead. Neither one of which would be much fun. I stopped doing the dragon because so many cars AND bikes coming toward me are in MY lane. If you can get it on a quiet day, it's about the most fun you can have when not in bed.
I also subscribe to the "rule of 100" regarding traction. I've experimented with it in parking lots and yeah, there is something to that.
