How Common Is Decidual Bleeding?

The importance of low-speed maneuvering



our driving lessons in the subject of low-speed maneuvering is a subject on which we so much emphasis, while a student suddenly less patient and less disciplined have thought that our secret goal is to extend the classes to end up charging more money. Nothing could be farther from reality.

Keep in mind that some practice is more or less easy to learn to take the bike in a straight line without being off all the time. It's not that complicated to begin to give little walk around the block while we feel the breeze on your face walking around the neighborhood or housing estate where we live. In fact, if you have good balance bike and knows how to handle car the process is still easier. For this is not surprising that students often come to us (almost always men) who say they know how to handle bike and want nothing more prepared to take the license (not unusual once want the A4 in front of 501 cc and without limit).

The real issue has to do with the approach that "no bike handles if you do not know how to control at low speed." Returning to the point handle almost exclusively on line, anyone can hop on the bike, get on track and accelerate to 100, 150, 200km / h if the bike and the road permit. Little merit is turn the throttle back and let the bike grip work momentum as the carburetor or fuel injection.

But then, what happens when this hypothetical rider street has just opened and has to start to slow down because a) there is a traffic jam ahead, b) he or she went through a dog suddenly stopped another driver, c ) enters a prolonged series of curves and counter radio unknown and the estimated right? is in these cases comes into play precision handling at low speed, braking and compression, a set of skills that are not necessarily able to just ride a bike (and I say this because I touched the brakes and work to correct turning right left on some applicants seeking experienced our service in preparation for A4). Now imagine these management deficiencies in a student less trained but already believes fledged biker ...


Not to be nothing more critically, we bring some of the key elements driving and low speed domain we work in our classrooms Motorcycle From Scratch:


1) Control of Clutch, Throttle and Brake Basic

Riding bike, if you learn well, is very far from the famous "metals first and give gas", which is how many people are taught to manage one other friend. First there that "play" with the clutch or clutch to see how much has the lever travel before they want to turn off the bike. Then you have to grab the touch the throttle, so we made sure not to give it more gas to the account to the bike and go out runaway. This fear is very common in freshmen, but after about 15-20 minutes to do exercises that will accurately indicate speed while watching the tachometer, they themselves are realizing that it is not so easy to leave the bike flying just give some acceleration. The third point is the basic braking, which is made up of 20 km / he involves both brakes so that stop the bike as a feather, or clavonazos smooth front suspension.


2) full turns to the left and right:

This is a fundamental exercise to handle the bike, especially if we consider that in the displacement of the bike paths and semi curves curves predominate . always at low speed and balancing the use of clutch and accelerator, we will give full turns around a fixed point (a cone, a bottle, a mark on the street, etc). The turns should be as symmetrical as possible circular (not elliptical) and at first it put your feet. Later, the goal will be to make the money without having to set foot at all. Returns must be so, so slow that the act of sinking the clutch lever from the bike power to miss most of the forward speed (transmission off). At this stage it is crucial not to apply the front brake, but the clutch to disconnect the transmission to the rear wheel and avoid the unwanted advances of the bike. By using the front brake while turning only thing we're going to get is that the inertia that carries the bike suddenly see transmitted to the front suspension, the front of the bike suddenly collapses and we end up falling on camera slow motion the inside of the turn ("duck drop"). Significantly, there is always a side to which costs us more to turn around (I call him "the weak side or difficult) and that is what we have to work twice. As a curiosity, the weak side to the right is the shift in the direction of clockwise, but lefties have had students who have difficulty with that side.


3) Check-in costs:

Tod @ s know or remember their own stories when we were learning to drive a car or motorcycle and we had to practice a cuestota of all demons. For my students @ s @ s I have always press forward a couple sleeve and almost always the sudan and I hate a few minutes, but eventually I always end up thanking the hard training for real life. The slope of the hill must go dosing according to the skill of the student and the ultimate goal will always be that it can dominate the gap with a passenger riding behind. To achieve this it is necessary to coordinate the use of brakes (either rear or front) and other controls (clutch and throttle) to the output. Keep in mind that if the bike is already showing willingness to go out but do not release the brake, let's finish off the bike. To exit costs and that my students have completely free hand throttle taught them to brake pedal. And with a little more practice is also good exercise in the same output but hold the bike with the front brake, which allows both feet on the ground and more stable (as in having to leave hill with a passenger back) .


4) Brake with additional passenger or cargo @:

If the distribution of ideal weight, at least for many modern bikes, has been close to 50% below and 50% rear, driving with passenger largely affects this relationship. Will never be the same going on the bike at 60 km / h stopping distance in X have to do what same with a passenger @ 50, 70 or 100 kilos. The quality, intensity and braking distance will change so drastically that we train constantly to acquire the control of braking without getting variables affect the weight of the passenger or cargo. The opposite is the sin of naivete and ignorance in the handling of the bike.


5) Exercise of cones "slalom"

There are many exercises with cones or obstacles that can be done to increase our domain expertise in the bike. One of the most common is the last of cones in sequence and reverse curves without putting your feet, playing, bouncing or skipping any of the cones. The obstacles may be in a straight line or slightly wavy (more difficult), but the trick is to calibrate the half turns between cones so that the front tire might happen in the pure through the two cones at an angle approximately 45 degrees. This is going to ensure a curved path that also keeps us away from the cone A and B cone, so we were careful not to go near any of it safe and even bounce or touch the obstacles. It should be mentioned that the cones can move rather quickly or slowly, but faster passing, more control to tilt, "bed" or "dance" we will need the bike. Although many believe this is a cumbersome exercise to pass test drive and win the license, the real-life application of this is to move at low speed between rows of parked semi trucks, and when we went to a dam or traffic congestion.



While there are many more exercises, along with variations and combinations of all of the above, we can say that these are at least as a major precision handling at low speed. Often I have to "land" to new students coming to class and believe that to know to start the engine and give a couple of times already "know" ride motorcycles. This is not a matter of ego, but of humility to learn and above all, learn well, because to the extent not control our bike, she is going to control us and that is very dangerous. remember that "no one manages bike if not controlled at low speed."
