My first degree was from Univ. of Kansas, and I worked in a motorcycle shop and raced short track and scrambles. One of the really good riders from the shop became obsessed with weight on the short track and started drilling holes in just about everything, and then started removing spokes from the wheels...yes, for weight! Here's a surprise, Frank (now long gone) lost a front wheel in turn three and did a high side flip. He lived but was busted up. The guys who did nothing for weight focused on h.p. and technique. Some of your guys seem to be engineer types. Where does the goofy line cross the sensibility/physics line on the graph?
