GEARING TABLE

8/29/2019

 
The MotoSPEC GEARING TABLE will calculate the swingarm length and final ratio, as determined by the countershaft location and swingarm geometry.

The user can specify the swingarm length and sprocket ranges, and only gearing options within those ranges will be presented in the GEARING TABLE.

The GEARING TABLE can be  sorted to present the gearing options for the most efficient decision making.


The Gearing Table calculates the swingarm length based on the tightest chain condition, where the front sprocket, pivot and rear sprocket are all aligned.

The Gearing Table can remain visible while making setup or chassis specification changes.

A quick guide is shown below.

Further explanation of the features of the Gearing Table is below the image.

COLUMN SELECTION:

The column buttons are visible only if the CHASSIS specification applies to more than one column (i.e. if there is only one CHASSIS button visible). 

For example, with a MotoSPEC STANDARD license or after importing an MS1 file into all three columns.

If the column buttons are not visible, it means that the CHASSIS specification opened applies only to a single column - for example, a MotoSPEC PRO license with a different file imported into each column.

Selecting the applicable column is only required if there is a difference in pivot adjustment in the columns, as the pivot adjustment will affect the swingarm length calculated.

The table will update if the column selection is changed, if each column has a different pivot adjustment.

FILTERS:

Below the column selection are the filters that are used to limit the gearing solutions presented in the Gearing Table.

There are filters for swingarm length, front sprocket and rear sprocket.
The solutions presented in the Gearing Table are only those that fall within the range of these filters. 

For example, as shown above, the Gearing Table will only display solutions with 595-615 mm swingarm length, front sprockets of 16 and 17 teeth, and 42-50 rear sprockets.

The table will update as the filters are modified.

STRETCH/TOLERANCE:

The Stretch/Tolerance value is added to the calculated swingarm length, to account for chassis variations and also for chain stretch.

If a common difference is found between the calculated and measured swingarm length regardless of chain condition, the difference can be entered in the Stretch/Tolerance cell, to make the calculated and measured equal.  This will account for manufacturing variations particular to your motorcycle - for example, engine mounting tolerances.

As the chain stretches, the Stretch/Tolerance value can be modified so that the measured values and the calculated values shown in the table are equal.

The table will update as the Stretch/Tolerance value is changed.

TABLE WITH LABELS:

The table has column labels, and the solutions are displayed in the rows.

If the table is taller than the displayed portion in the window, the slider on the right side can be used to change the displayed portion.

The table can be sorted by clicking on the labels.   The arrow beside each label shows if it is sorted in increasing or decreasing order, and the sorting direction can be reversed by clicking on the label until the desired sorting direction is achieved.
