A mers cineva?Cat de repede fuge?e mult mai ne-permisiva ca masina pe ud mai ales?in curba daca ai dat gaz 1 sec mai repede esti pe jos direct?sunt mituri sau e mult mai periculos?

Cu siguranta e mult mai periculos decat la masina, pentru ca au un singur punct de contact cu asfaltul la "puntea" spate, iar daca roata prinde o pietricica nu mai are cine sa te tina pe traiectorie.

Yamaha YZM 426 WR are tractiune pe ambele roti.

http://www.yamaha-motor-europe.com/designc...cm71-245322.jpg

Yamaha TT 600 a fost prima motocicleta cu tractiune pe ambele roti.

http://www.yamaha-motor-europe.com/designc...cm71-245298.jpg

The hydraulic pressure lines simply go from the engine mounted drive motor to a regulator under the seat and then to the front wheel. The hydraulic pressure flows in a circle.

HOW THE WR450F 2-TRAC WORKS
The patented 2-Trac system uses a hydraulic pump situated on top of the gearbox, and a chain running in an oil bath drives the mechanism. The system pumps hydraulic fluid via high-pressure hoses to the front wheel hub which is fitted with a hydraulic motor equipped with a single gear. When the fluid has passed through the motor it passes through a filter and returns to the pump.

Sincer am mers in acest week-end cam 650 km cu un Yamaha YZF R6 si pot spune ca nu a existat moment in care sa simt ca ar fugi spatele, acele idei cu pietricele si alte nebunii sant spuse de oameni care nu au mers cu motocicleta si care ppur si simplu la gandesc din cap (ca asa ar fii normal), in toti acesti 650km am prins si ploaie si soare, singurul moment de nesiguranta a fost pe A1 la 240 km/h moment in care pur si simplu am turbat de frica cha (40).gif . In rest.... sper ca pe viitor sa pot merge mai mult pe motocicleta astfel incat sa imi dau seama mai bine ce inseamna.
