Front suspension – FFE software

Description

Tony Foale says “I frequently needed to do such calculations and developed this FFE software to fill the gap purely for my own work. However, as word got around of its existence I received a number of requests from interested people wanting to buy copies of the software. I have developed it over time to make this software comprehensive and easy to use.”

We knew of no other software suitable for analysing various parameters of interest, such as anti-dive, rake, trail variation etc. for that class of motorcycle front suspension controlled by some form of swing-arm and/or pivoted links. The oft used term “Hub-centre steering” doesn’t cover the whole range of these alternative designs and we use the all inclusive term of FFE or “Funny Front Ends”. 

What it will do?
The software will analyze most forms of FFE suspension. It will put numbers to many characteristics. Viz: anti-dive percentage, rake angle variation, trail variation, wheel trajectory and many suspension parameters
It will graph these parameters against suspension movement.
Designs which fit into this category include, hub centre steered designs such as Difazio, Bimota etc. and other FFE designs such as Hossack, BMW duolever, many of the Elf designs, Foale/Parker/Yamaha GTS and many many more. It will also handle head stock mounted forks like girders and leading/trailing link.

The latest version can now import rear suspension data generated by our “Motorcycle Setup” software.  This feature refines the calculations of dive and variations in the geometric parameters such as rake and trail variation.  Check out our special bundle offers for both software packages.

What it will not do.
It will not handle any system with sliding elements such as the Saxon/BMW telelever type.
