Are you retarded or what that you do not understand the difference between an engineer and a rider who develops the bike?
Max Biaggi, when was at the yam, apparently once came back to the box, just got off the bike and when asked what was wrong with the bike he said angry "I don't know, it just doesn't work". And left.
The Yam Engineers said this of VR: "he comes back and describes very accurately what he's seen in each turn, the sensations, the bike behaviour etc, we look at the data on the screen and see exactly what he is describing to us there".
When VR says "I'm not an engineer", it means this: I can tell you where the bike is working, what's good, what's bad, what I need whether I think we should use a brutal powerful engine or one which is softer but gives less speed etc. I CAN'T HOWEVER DO THE MECHANICAL DESIGN WHICH WILL PUT INTO PRACTICE THOSE REQUIREMENTS, I CAN't GO INTO THE DETAILS OF MATERIALS TO USE, BIKE DYNAMICS, RIGIDITIES ETC ETC ETC.
You say you ride a bike and can't understand the differnece between a rider who develops well a bike and another who hasn't got a clue? Have you ever heard the praise engineers had for drivers like Senna and Schumacher? I am doubting your brain abilities.
