Ive got a big pot of dimple finish GOLF BALL PAINT,GOLF BALLS,GOLF BALLS,GOLF BALLS,
I got told off last time I mentioned them,
I do think that the only real way of testing aerodynamics is wind tunnel testing.
some early faired bikes actually had more drag than there un faired counter parts,narrow/small/pointy frontal area isnt always the way to go either.
love it or hate it the Hayabusa is by and large the most slippy through the air stock motorcycle personaly I think they look awful and if you had asked me 15or so years ago what an aerodynamic bike would look like it certainly wouldnt have been a Busa but the Japanese invested a load of time and god knows how much money making it that way
Sometimes adding random lumps and bumps in the most unusuall places can have a huge effect on aerodynamics but without a tunnel its very hit and miss.
ps.Ignore the Golf Ball bit but apparently someone mentions it every year, and its about a year since I mentioned it last time!!
Ignore me I am bored and I want to go to Bonneville NOW!!!!
