Dunlop has provided the inflated profiles for their flat-track tires - the new tubeless DT4's and also the pre-2020 tubed DT3's.
For PRO licenses, the tire specifications now include radial stiffness.
Using the profile and radial stiffness, MotoSPEC v5.7 can calculate the 'loaded radius' of the tire with lean angle, improving the accuracy of the geometry calculations.
MotoSPEC can map a Ride Height Gauge into the chassis specifications.
MotoSPEC will then calculate and display the ride height measurement corresponding to the chassis settings.
This allows rear ride height to be accurately maintained or modified while exploring setup options, and the shock length or ride height adjustment can be specified when generating build sheets for mechanics.
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 SETUP SHEET function can be used to write out chassis setting or geometry values directly from MotoSPEC into an Excel spreadsheet.
This eliminates the duplicate entry of values in MotoSPEC and the user's Excel setup sheet, saving time copying these values for record-keeping or when creating build sheets for mechanics.
The cell address for each value is specified once, and then all the desired values can be written out with just a couple of mouse clicks. The file, column and row specifications are retained after MotoSPEC is closed, so that they are available the next time that the SETUP SHEET is used.
Dunlop has recently provided the profiles for tires used in road-racing and flat-track.
These dimensions are generated from laser scans of the inflated profiles, and are different from the rolling radius profiles that are intended for traction control.
The PageUp and PageDown keys can be used to increment the value of each setting in the three columns.
The 'Import HED file' function will fill the settings in one or all MotoSPEC columns from a 2D HED file.
This reduces the duplication of entering setup information in both 2D and MotoSPEC.
This feature can be found under 'DATA AQ'>'Import HED file'.
Inserts in the steering head or headstock of the frame can be used to adjust the rake and the weight distribution of the motorcycle.
MotoSPEC can specify these inserts in several ways, to accommodate all the different methods in use.
MotoSPEC v5.6.1 added a setting that will indicate the forward reference for the swingarm length.
Swingarm length is typically measured from the swingarm pivot axis to the rear axle. On most motorcycles, the swingarm pivot is visible and accessible.
For Ducati Panigale V2 and V4 models with adjustable swingarm pivots, the eccentric adjustment occurs inboard of the swingarm bracket - so the swingarm pivot axis is not directly accessible for measurement.
The calculations for swingarm and chassis geometry now consider the offset between the frame center and the actual swingarm pivot.
