I am wrong? Wanna bet? Google gyroscope and motorcycles together and then post facts instead of your opinion. Here’s a sample of what you will get.

"Basic Explanation: As the gyroscope spins, the force of the spinning causes the gyroscope to want to stay upright and be stable.
As with the motorcycle tire: As the front motorcycle tire spins, the force of the spinning causes the motorcycle body to want to stay upright and be stable.

What happens when you push steer (counter-steer) is you only temporarily (as long as you are pushing on the bar) leaning the motorcycle to the left or right while looking where you want to go. It requires MORE force to lean the motorcycle to the left or right than it does to bring it straight back up because of the gyroscopic effect. Thus the motorcycle always wants to be stable and will bring itself back up right and therefore the motorcycle won't fall down. "

This explanation is readable but if you want a more scientific (physics) explanation, just google it.

 

Chance are your stock Sporty can handle tighter turns than you'll be able to muster for some time. I would look to improve your cornering technique before spending any $ on mods. Learning to take the proper line through a turn, transferring weight to footpegs, shifting your rear to the inside of turn will all make you turn much tighter without leaning any further (or making any mods). There are numerous excellent books on the subject. Check out Amazon or look for recommendations in previous posts.

 

I find leaning fwd over the tank makes my nightster handle more better...

 

Yeah its not a well-balanced bike.

Add 2-3 inches to the rear suspension and you'll blow other sportsters out of the corners. The rake and trail is changed for the better.
