MotoGP technology: Video - why a back wheel wears out quicker than forward?


In video it is very visually shown why the back wheel of a prototype of MotoGP wears out quicker than forward: because rotates quicker! And why it occurs? The answer - here.

of Prichin is simple: it is put in the nature of tires like Slick which are used in races - they provide excellent with zayets, at the same time, constantly being scrolled. The actual rotation of a back wheel is 8-12% more, than at forward as the back tire is affected by huge torque from the engine, as pushes the motorcycle forward. The tire transfers to asphalt not 100% of the initial moment and energy! To deliver to asphalt it is as much as possible moment - in it and work of army of factory engineers and also engineers of racing teams consists.

A affects a forward wheel only swing friction force. Therefore the speed of rotation of a forward wheel - the true speed of the motorcycle.

back a wheel significantly influence such factors as a motorcycle inclination in turn (the contact spot decreases - resistance of a tire decreases) coefficient of scrolling and a manner of driving of the pilot: many prefer to start up a back wheel in long stalling "to cut off" a part of the turn. The forward wheel at the same time constantly is in contact with asphalt and provides to the motorcycle stability.

At a torque surplus on a wheel and too good hook begins effect of Wheelie - a reverse side of stalling.
