These are totally free with no adverts nor invasive popups.

Description

These are 32+ bit PC programmes and are compatible with Windows 9x and later, and should work with a Windows emulator on Macs and Linux.

All of these programmes are in a single zip file which can be downloaded to a folder of your choosing.  Open the zip file and use whichever software is of interest.  Most will just run without additional installation but there are some which require installation, but that will be obvious when you open the file/s.


Steering Geometry calculator.

This programme calculates steering geometry parameters. Rake, trail and offset.

CoG and weight distribution calculator.

This programme calculates the mass centre, moments of inertia and weight distribution of a motorcycle when the masses and CoG locations of various components are input. In addition there is information to help with calculating CoG positions for riders. 

CoG and weight distribution calculator 2.

Different to the programme above. This software calculates the CoG position based on data from weight measurements of the assembled motorcycle. 

Structural sections calculator.

This programme calculates and saves the structural properties of round and rectangular sections such as used in chassis construction.

Tube profile cutting guide.

This programme called “TubeMiter” was written by Giles Puckett and is here with his permission. You can input sizes of two round tubes that you wish to join together by notching one of them, the programme will then allow you to print a paper template which can be wrapped around the tube as a guide to cut the right shape. It will handle tube sizes of up to about 80 mm. diam. This limit is set by the size of the paper in your printer. This programme has no use unless you are actually constructing a tubular structure.
