2013 Correlation Between Machine and Motor Speed ​​Teeth At Every Position

Correlation Between Machine and Motor Speed ​​Teeth At Every Position
This correlation can be qualified by knowing reduction ratio each tooth and rear wheel diameter (effective diameter of the tire / tire effective diameter)

If the engine turns the motor around 400 rpm , the motor speed will ranges from 10 km / h in 1st gear , the 2nd gear around 17 km / h , the teeth 3 about 25 km / h in 4th gear and about 30 km / h . If the engine rev added another 1000 rpm to 5000 rpm , power and torque of the engine also increased , which rnemungkinkan motors can climb / hike and generate the necessary power . Maximum speed is the speed of the engine practically generated in each gear position . YB motor 50 rounds maximum engine 7000 rpm . Motor speed will decrease slowly after past the 7000 rpm rotation that indicates rotation maximum . However , when the engine rotation was increased to 8000 up to 9000 rpm , the motor speed has also increased, but dorohg power the rear wheels is reduced gradually and the actual
speed was not increased in these circumstances . Therefore , the performance testing engine acceleration , engine rpm is raised at maximum value of 7000 rpm in 4th gear . Raise the engine rev
thrust to the rear wheels is reduced gradually so-called " over-revolution " and can shorten the life of the machine . At tachometer there is a warning for overreving this area .
