cornering and g-forces..

I was out on a late night high speed adventure the other night and I had the bike up on the limiter in sixth.. (my zx-10 will hit the limiter because I can feel it surging) anyhow I had a right hand sweeper ahead so I stayed in the throttle and proceeded to make my turn. I have a speedohealer and it was right at 183-4 indicated when the limiter was stepping in...as I went through the corner I could hear the r's being pulled down and as I looked down I seen that my speedo was at 169..so the corner had rubbed about 14-15 mph off of my speed. I've had that same thing happen to me before but at slower speeds.. it's amazing the cornering forces that must be present at high speeds/lean angles...another section I hit at about 135-140 and after the corner it scrubs about 5 mph off..
No real point here I just found it interesting..

I know thats how I slow down alot at the track...goin into a decreasing radius turn or whatever...just lean the bike over and let the bike slow itself down!

When you turn you are actually accelerating. Acceleration=change in speed or direction.

turns = more mph actually unless you are truely letting of the throttle

At that speed,Maybe the tires were scrubbing off speed because of wheelspin or just as you stated g-forces! I wish I could corner on the limiter!!

Is it Fast?

Better Idea yet, Maybe the clutch was slipping and that was the surging you felt!

I completly dissagree.

Acceleration - change in velocity, also the rate of that change

A 1000 kg car is going around a curve with radius 30 meters. If the coefficient of friction between the car's tires and the road is 0.5, what is the maximum speed at which the car can make the turn?
Solution:
  • mass of car, m = 1000 kg
  • radius of curve, r = 30 m
  • coefficient of friction, = 0.5
  • free-fall acceleration, g = 9.8 m/s2
  • maximum speed in the turn, v = ?




In the vertical direction, N = mg. In the horizontal direction:
Fnet = Fcentripetal = f

Obviously, if the radius of the turn was infinate, you would never stop gaining mph, in theory. We all know with gravity and wind resistance, this doesn't happen.

When going straight, the only thing you have is the amount of gravity (weight) acting on you bike for friction. When youre in a turn, you have the weight and a vectoring force (centripital) added to you, thus making you need more friction to maintain the arch.

More friction = less speed

I'll say... and right on the money....

Those of you that think you accellerate through the turn at high cornering forces need to twist that wrist a little and put some REAL cornering forces on yourself and your bike..then you'll see what I'm talking about...
