Center, LA CA Lines: 16 <> The comments about special drag-reducing paint on aircraft [...] towards the end of one of these exercises that a clean bike goes faster, and I'm afraid he said it to me often enough that I began to believe it, rationalizing about drag coefficients. I'd like to hear what others think. Well yes, a very clean and waxed bike will have a lower coefficient of drag that a dirty bike. Unfortunatly the primary component of aerodynamic drag on a motorcycle is parasitic drag (rider, handle bars, engine,&tc.). I suspect that washing and waxing a bike makes no detectable difference. -- Stephen C.
