The AIS Superbike is similar in design to the Lotus 108 and is shown along with a screen shot of the Finite Element Analysis for the frame. The points of highest stress are shown midway on the bottom edge of the main member and midway between the bottom bracket and the rear drop outs which is what an engineer would expect to see. It shows that the stresses are relatively even, with no significantly high concentrations of stress. The Yamaguchi would most probably show high concentrations of stresses, indicated by shades from red to purple which would concern an engineer. As much as I am a fan of steel frames(I have one carbon frame, one aluminium and a dozen steel frames), the beauty of carbon fibre over steel is the ability to add another couple of sheets of carbon fibre to reinforce areas of high stress, thereby evening the stress loadings.

id suggest to continue this conversation after seeing mentioned koichi frame stress visualisations.
and both bikes are lust, although the lotus seems a little too extravagant for me.
