TRIeagle
Tech Links
Good web page on "Rake and Trail".   
Trail determines how well your trike will
handle at slow and highway speeds.
A great link to some great tech
info/fabrication.  This is a link to the KS-1
website (why reinvent the wheel?)  I  can
vouch for "Sonny's tow thingy" (works
great!) and the shocker front end (it's
mine!)
