Some of these links lead to people I correspond with, some to people whose work I respect, but what is common to all these places is that they will show you some quality work dedicated to vehicle science or good design.

Some people call this "cool links"...
   

www.tiltingvehicle.net Phillip James of Oz, an inventor who made more successfull tilting three wheeler prototypes than the entire european automotive industry, and thed did try ; )
www.maxmatic.com A web site dedicated to tilting three wheelers, and obviously represents years of collecting data about my currently favorite subject.
www.tonyfoale.com Homepage of Tony Foale, writer of the book about motorcycle chassis design and a lot more. What is even more interesting, you can practically follow his life path on this site and see what you have to do to be one of the world's leading men in the job of motorcycle design and building. Also a gallery of carefully selected photos.
www.glynn.de Motorcycles to pretty to be true, hand drawn on paper, without any technical impossibilities that I noticed ( which are usual for futuristic design), here presented ideas stand a couple of years ahead of what you can see on the street. Most probably because it is the homepage of Glynn Kerr, one of the world's leading motorcycle stylists/designers.
tilting This is a Yahoo newsgroup that I am a member of, and here you can see thoughts and ideas about tilting three wheelers shared among the worldwide spread group of people, enthusiasts, (midnight) engineers. inventors, college professors...
www.drysdalev8.com Site of Drysdale Motorcycle Co. of Oz, V8 powered motorcycles, 2WD-2WS motorcycle and a load of interesting motorcycle and engineering related subjects done by Ian Drysdale.
www.britten.co.nz Site dedicated to John Britten and his project. John Britten was an inventor/engineer from New Zealand and evidence that "The little guy" with his workshop and hands can beat the multibillion global industrial enterprises, on the racetrack, where quality of the job done makes all the difference. Too bad Tul-Aris doesn't have a web page as well, so search for it yourself.
MDRG/Padua Motorcycle Dynamics Research Group is a group of engineers at the Technical University in Padua, Italy, and among the people that present their work from the area of motorcycle dynamics on the Internet, these are the very best. On this site you can also see a TTW project designed.
Animation Master This site is about Animation Master, the cheapest software available for computer design and animation, in this case it is digital arts and not motorcycle design. Here you can see great galleries of images generated using AM.
www.eurospares.com Lots of great images and stories exibiting motorcycling handicraft of people worldwide, created through the years by Michael Moore of San Francisco.
www.uspto.gov Official site of US Patent and Trademark Office, the place where all the knowledge of the world is stored. There is no singular site on the Internet that is a greater databank for technical inovation and machine design solutions.
www.ducati.com Real and true, web site of the company that makes the best twowheelers.
www.carver.nl Van den Brink, site about the only serial produced tilting three wheeler, the Carver, where you can see a good presentation of a TTW that went further than all.
