The Chapter 19. Taxiing - reference taxiing

In places you concern a motorcycle? On what you rested at taxiing? Whether more difficultly to taxi, if you do not have firm bearing? Whether there are places for a bearing at taxiing? What designs of a motorcycle from them correspond?

Error at shifting

The reference taxiing means efficiency. I have paid attention to this method, when has noted, that 90 % of my students can not fast shift bike on the right - on the left - to the right, as it is done by the racers, attempting to warm up trunks. Not, that bike did not turn. Simplly racer dragged it from the party in the party under itself, as in cross-country race instead of shifting it, moving together with it.

For a motorcycle going on mineral pitch, such style does not approach, he causes to use large, than it is necessary, angle of leans, that does taxiing by extremely unefficient. You see if you can pass turn by smaller angle of lean at a preset speed, it goes only on advantage and you and bike. Contrast of moving in a rig - hooking. It just gives that is necessary in turn - smaller corner at a preset speed. Let's consider hooking more dital.

My discovering

Piloting 250-cc Grand Prix, I have made interesting discovering. On Road America there is a lengthy and fast turn, which one needs to be driven on a footstep or sixth transfer. So, the taxiing on a men lasts approximately 3 1 seconds, or even longer. It in two - four times is more, than usually. And more I have noted, that, despite of a rough surface of a route and the incessant acceleration, bike does not yaw, as it usually happens in that case. And on a following circle I have noted a striking thing there is I has used an external step as fulcrum

The riddle was settled. My weight was lower on 12 in.s, than if I rested on a saddle or tank. Therefore motorcycle also did not yaw.

Reallocating of weight

Usages of an external step as fulcrums, besides that the working point is on a control surface (you it thrust or both thrust and pull), reduces your weight applied on a saddle, and transfers a part it in more low point. And unless bike will not be straightened if to be rested against an external step? At all no, do not overlook about a gyroscopic effect created by sprockets.

Actually, as your weight becomes closer to a center of mass, to taxi begins is more lighter. The motorcycle is turned around of a center of mass, so that the weights there more is massed, the is more lighter to turn. Besides the stability is enriched. Your body any more does not work, as a satellite located far from center. Bike "thinks", that you become closer to his center of mass.

Force of a body

One more advantage - you become is stronger. Than more lever the better. The racer will use for a bearing most distant from a control surface a point. All other fulcrums do not give such strong effect.

Besides you can better use muscles of a torse for taxiing. Any other fulcrum hinders completely to involve these muscles. Certainly, it is possible to do without and them, but with them is more lighter to taxi. You see at taxiing the counterforce tries to turn your torse, and than better muscles resist to her, the more stable design.

Moving in a rig

At moving in a rig the racer has no fulcrum and is compelled to use for stabilization all weight of a body. It how to attempt to thrust something, floating in water - you too rejects. Besides such style demands pressure almost of all muscles of a body, that results in a unjustifiable fatigue.

Advantage

Even if you will be rested by an elbow against a tank, will push legs to a lining, lie on a tank by a chest, densely sid in a saddle, will rest legs against steps and from all forces will shrink a control surface, all of you equally do not receive such advantage, as though you simplly have used reference taxiing with fulcrum only on an external step. The reference taxiing completely corresponds to a machine design and provides such stability of taxiing, which one cannot be reached by other ways. But in all the skill is necessary, spend the time for development of this method.

Remark, on and also other kinds of motorcycles with borne forward by steps, this method does not work. The rule of a step eliminates its usage as fulcrum.

Where and when

You should be retrained to run in power taxiing. It has taken me approximately 2,5 hours, then I applied this method automatically. On the other hand, once I learned the "street" driver, the speed of taxiing which one was somewhere in region of three balls on a ten-mark scale. We worked basically above contr-taxiing and reference taxiing. And only in 1,5 hours for it began a little to receive in one turn from 20.

I long could not understand, why for it so slowly studies, has not thought yet, that actually tests double difficulties. You see he simultaneously masters and contr-taxiing and reference taxiing. He simplly is afraid to choke bike too fast. So that you at improvement of this method should overcome the pavor and to be massed on exact fulfilment of exercises.

Fulcrums

Actually any fulcrum is useful. See at equipment of the foremans. An internal surface of their hoses dirty, because they rest by it on a tank during taxiing. The aluminium parts of motorcycles up to lusters there, where them concern raning boots. An internal surface trousers and seat of a motorcycle are worn there, where they are abuted. And so on. To put it briefly, at reference taxiing you can use any fulcrums and their speed keys, if only it was beneficial for efficiency and accuracy of taxiing.

Exercise

For the beginning define, what fulcrums you usually will use. Then try to apply reference taxiing and compare outcomes. You will remark, that the left-hand turns differ from dextral, it because of control of gas. At turn to the right you can both thrust and pull, can only thrust. At turn on the left - to the contrary. Actually, it practically does not influence efficiency, the method works equally well in both cases.

Interestingly, as though you have called this method? Taxiing diagonally? You see you will use inverse points as fulcrum and working point. Center taxiing? You you see as though taxi from a center of mass. New taxiing? You see it is new technology. I name it by reference taxiing, as you taxi with the help of definite and stable fulcrum. Call as want, main, what is it works high performancely.


For the beginning try to use as fulcrum a seat, then elbow, and so step-by-step come nearer to usage of a step. This method will supply stability in fast-track turns. DG
