Calculators and ComparatorsBike: Moto: Auto: Universal: GEAR RATIO  it is the ratio between the driver shaft angular speed and the driven shaft angular speed from the gearbox. In other words the ratio between the number of teeth of the driven sprocket that is on the driven shaft in the gearbox and the number of teeth of the driver sprocket that is on the in shaft coupled to the engine with the clutch. Example: 3.17:1 which means 3.17 rotations of the motor shaft at 1 rotation of the driven shaft. In this case we input 3.17 in the calculator. You can find these ratios here. FINAL DRIVE RATIO  has the same definition with the gear ratio with the specification that the drive it refers to is between the driven shaft and the shaft that transmits the movement to the wheel. Pmax/RPM  indicates the maximum power developed by the engine and the rotation speed at which it occurs. It's measured in KW. See the difference between HP & HF (Horse Force). Tmax/RPM  indicates the maximum torque developed by the engine and the rotation speed at which it occurs. It's measured in Nm. Wighted average power  is the division of total energy converted to force by the total time needed to accelerate on all the RPM range. It's measured in J/s. Wighted average torque  indicates the average torque developed by the engine on all its RPM range. It's measured in Nm and is the second clearest (after Equivalent constant engine torque) characteristic of an engine (if it is mentioned alone without other information/characteristics). Details... Equivalent constant engine torque  is the torque with which a car's engine with one gear ratio can accelerate over the same distance in the same time, providing a single value as a characteristic for that engine on all its rpm range. It's measured in Nm and is the clearest characteristic of an engine (if it is mentioned alone without other information/characteristics). Details...

Tyre (tyres) Info Height (mm): Diameter (mm): Circumference (mm): Speed (km/h):
OBSERVATIONS:
a. Changing the tyre/wheel dimensions influences only the real speed (Attention, not the one indicated by the gauge!) and the force applied at the circumference of the traction wheel:  by lowering the diameter, the force applied at the circumference of the traction wheel will rise and the real speed will drop,  by rising the diameter, the force applied at the circumference of the traction wheel will drop and the real speed will rise.  this force applied at the circumference of the traction wheel is influenced also by it's mass => it's inertia. b. The torque at the traction wheel changes only by changing gear, not by changing the diameter or mass of the wheel. c. The power at the traction wheel is equal with the power at the flywheel minus the losses through friction in the transmission. So, the power at the traction wheel does not vary by it's diameter (it varies by it's mass/inertia). Therefore results that for the same power at the traction wheel there are multiple values for the force (that is influenced by the wheel's mass so we are discussing about equal masses and equal distribution of the mass for different diameters) applied at it's circumference and so, a different behaviour of the motorcycle.

OBS. 1.The torque at the traction wheel doesn't change if the tyre is changed. By changing
Torque [Nm], rotational speed [RPM] and work rate [J/s] The air drag IS taken into consideration in the actual calculation.
Graph 1The green area below the torque graph represents ROUGHLY the average power of the engine (63790.2800 J/s between 2799.83 and 11896 RPM). Because the speed of the RPM increase is variable, a more accurate measure is the ENGINE'S TIME WEIGHTED AVERAGE TORQUE (54.8161 Nm between 2799.83 and 11896 RPM).
Force [N], acceleration [m/s2] and speed [km/h] The air drag IS taken into consideration in the actual calculation.
Graph 2^^ The above graph is useful only if rotational speed values and respectively torque values of the engine from the torque chart were inputted and it refers, especially, to 190 / 50 R 17 wheel, / R wheel having displayed only the graph of total force at their circumference depending on the rotational speed of the engine, in 1st gear (for keeping the graph readable).
For maximum performance, the gold colored lines "Shift __" from the above graph must be ~HORIZONTAL ! Graph 3^^ The above graph is useful only if rotational speed values and respectively torque values of the engine from the torque chart were inputted and it refers only to 190 / 50 R 17 wheel.
For maximum performance, the gold colored lines "Shift __" from the above graph must NOT be visible ! Graph 3^^^ (air resistance included) This graph appears only if values for air resistance calculation (drag coefficient, reference area and air's density) were inputted.
For example, the first two can be found here.
Acceleration time [s`] [s`] The shifting time is NOT included.
Graph 4^^The colored areas below each graph line represent the acceleration time. The time needed for shifting gears is considered to be 0. This graph displays the inverse of acceleration that is generated by the engine+transmission depending on the speed, without taking into consideration the transmission losses. Graph 4^^^ (air resistance included) This graph appears only if values for air resistance calculation (drag coefficient, reference area and air's density) were inputted.

Energy [J] transformed into force [N] depending on distance [m] The air drag IS taken into consideration in the actual calculation.
Graph 7^^This graph displays the energy transformed in force depending on the distance covered, without taking into consideration the transmission losses. The energy transformed in force is calculated as the surface under the force's graph depending on distance covered. Because the torque graph contains only 15 points, errors occur when calculating the time, distance and energy. The total energy transformed in force between 30.77 and 286.28 km/h is equal with the difference between the kinetic energies for these two speeds: 793.820 KJ. Graph 7^^^ (air resistance included) This graph appears only if values for air resistance calculation (drag coefficient, reference area and air's density) were inputted.
For example, the first two can be found here.
