QuestionI'm 40 now, but I never performed a knee-down (i only ride fast bikes). I ride a hayabusa, which i think should do the job. How do I do a knee-down???
AnswerBuy a good set of racing leathers (one piece) with knee pucks. Buy the best pair of boots you can afford. Buy the best pair of gloves you can afford. Buy a new helmet, back protector, and about 24 bottles of water. Buy the stickiest street tires you can find that will fit your bike. Read the book "Track Day Handbook" by Kent Larson. Then sign up for a track day--get down on your knee and play!
Getting your knee down is a by-product, and not a goal, of riding fast. And it's only worth bragging about if you do it the right way. By that I mean you're cornering your bike at it's absolute limit, using your knee as a gauge for your cornering clearance.
Riding a sport-touring bike on a track--if you're a talented rider--will take you to the limits of your cornering clearance fairly quickly. You'll then be required to use body English (aka hanging off) to keep the bike from scraping pegs or hard parts. Once you get the "hang" of it, your knee will tell you how fast you can go. Once you get it down, you're at your limit.
The street is NOT the place to ride your bike at it's limit. There are too many variables like traffic, gravel, animals, law enforcement, trees, ditches, brick walls, and sheer cliffs. Get thee too the track! You won't regret it.
I hope that helps answer your question.
