I sent them a number of ideas, but the one which intrigues me the most is an idea I had about filling a tire with a type of metal alloy which melts at a temperature slightly lower than that of boiling water. I may have posted something about that a couple months ago, don’t recall. A eutectic alloy of tin, lead and bismuth makes a high density, low melting point metal (about 97C) which you could use to fill a motorcycle tire. It would look perfectly normal but would weight over 200 kg for the front and nearly 300 for the back. <o:p></o:p></span></pre><pre><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></pre><pre><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>If you had one on the front and everything else normal, the CG of the bike/rider combination would be moved down and forward, which would allow a prole to ride up ramps of impossible-looking angles, assuming of course one had some kind of traction enhancement, such as vertical nail points poking up about half a cm.<o:p></o:p></span></pre><pre><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></pre><pre><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>What I don’t know is how it would handle, with the gyroscopic effect increased by a factor of about 30.
