How does the linked brakes change things. If I just hit the handbrake, is that going to give me good results?You mean you applied both front and rear brakes to scrub off a little speed.....linked braking system, remember?

Simply means that no matter which lever you use, your applying both front and rear brakes.How does the linked brakes change things. If I just hit the handbrake, is that going to give me good results?
I taught both middle and high school physics and it caused a huge amount of confusion that had to be overcome. I investigated traffic collisions for 26 years and most officers haven't taken even high school physics, and that imaginary force lead to erroneous conclusions which had to be corrected. I'm now teaching motorcycle lessons to beginning students and the confusion shows up there as well on occasion. Momentum (or inertia if your prefer) is 90 degrees from the erroneously perceived centrifugal force. As you mentioned, most of the time it doesn't make a practical difference but when trying to explain what is happening, it does make a difference.I took high school physics as well and while it may not be a force when applying the laws of motion it seems to be when on a carnival ride, and if in reality it is just your body wanting to continue in a straight line what difference does it make?
Keeping to the KISS method....how many of you folks having trouble with counter steering grip the tank with your knees while riding?
I see folks all the time, complaining about steering issues, or tire issues, riding with their knees flying out in the breeze! This means they are simply sitting on top of the bike with very little control.
Those of you who have raced dirt bikes, know what I am talking about. I used to wear the paint right off the side of my dirt bike tanks from gripping them.
Gives you ALOT more control and feel, as well as taking unwanted weight and pressure off the bars.
Try it, you may be surprised.
Ok no teacher here and a fuzzy memory, but basics that you need to know is that you want to continue in a straight line, so when going around a curve it feels like you are being pushed out of the circle but the reality is that you want to continue straight. The end result is that you have to force yourself to travel around the circle, the faster your speed the greater the force you have to overcome. I really believe in day to day life it makes no difference if you believe that the real force is acting on you or that the imaginary force of the black arrow is.I admit I am not sure what Jonz is going on about. I never took physics.
That was an excellent description of why centrifugal isn't "real", but you REALLY feel it.Ok no teacher here and a fuzzy memory, but basics that you need to know is that you want to continue in a straight line, so when going around a curve it feels like you are being pushed out of the circle but the reality is that you want to continue straight.

Yes of course the red arrow is the direction you fly when you let go of the playground turntable. I concur..for what that's worth.Ok no teacher here and a fuzzy memory, but basics that you need to know is that you want to continue in a straight line, so when going around a curve it feels like you are being pushed out of the circle but the reality is that you want to continue straight.

Yes, my question was answered some time ago. I have actually been out twice practicing. So I am good. But you all are welcome to keep the discussion going. This is all over my head.The OP was merely relating how his lack of attention on the road was causing him some grief when he got into a curve.
According to Wikipedia gyroscopic precession only plays a small part in countersteering compared to the force resulting from the out-tracking of the front wheel as we countersteer. Gyroscopic precession is more important in racing as the resulting force causing the bike to lean is immediate, however much smaller than countersteering.Here's something no one has brought up about steering around a curve though, the actual term for how we do it. It's called gyroscopic precession. Understand that and you will understand why we push left - go left and push right - go right.
Be careful , remember Wikipedia can be wrote by anyone. I read once that 80% of what you read there is not true, according to a study by Benjamin Franklin.According to Wikipedia gyroscopic precession...
Did you ever have one of those little string powered gyroscopes as a kid? Just as Roger is alluding to in his post about the spinning bicycle wheel, you might have found how it was difficult to change the attitude of that gyroscope in space, as it resisted going in the direction you were trying to turn it. The front wheel (and back also) are very effective as gyroscopes at speed and the action we call counter steering is the method we employ to initiate the precession force we need to overcome the gyroscopic effect of the wheel. That much is not rocket science. You absolutely will never get a heavy motorcycle to turn right or left, at speed, without first using counter steering. Hanging off, or otherwise redistributing your weight will add to the lean angles possible, but you won't be leaning at all without having used gyroscopic precession to start the process.According to Wikipedia gyroscopic precession only plays a small part in countersteering compared to the force resulting from the out-tracking of the front wheel as we countersteer.

Would be effective and a good reason to have the engine turning the more traditional direction than the Honda ST's do. But the in line rotation only stops us from turning while moving forward, will not be not stopping us from falling over.Anyone who wants to challenge themselves to see how slow they can go without losing balance, only needs to keep the revs up a bit while slipping the clutch. The gyro that is your crankshaft will help to keep the bike from falling over at very slow speed.
I guess you have never tried it to actually feel the effect. I'm not saying you won't fall over at some point, for the ST isn't like that new Honda that simply WON'T fall over, but that heavy crankshaft rotating at about 1500 rpm will help keep balance at very slow speed.But the in line rotation only stops us from turning while moving forward, will not be not stopping us from falling over.
