Wings and Aero Stuff on GP bikes?

    Well over 30 years ago, Phil Read's MV had small "canard" fins fitted
    to the fairing sides. That has been the only obvious bit of car-style
    aero work I've seen on bikes. What else have people tried? I suspect
    that a 45-deg leaning bike does NOT want any more downforce applied at
    45 degs. Do the factory GP bikes use anything that's no obvious and
    out in the airstream?

    Another related question: in the 1960's it was common on UK and
    European drag bikes to see full "dustbin" fairings that enclosed the
    front wheel and forks, down to inches from the road (I think even some
    Manx racers like Geoff Duke used them). Why have they disappeared?

    Cheers

    Sheer power available now compared to then ?

    In "those Days" wasn't better aerodynamics the easiest way to go
    faster rather than work on increasing enginepower ?

    Just a wild guess.

  4. If airfoils on the upper part of the factory Yamahas could be classed as
    not obvious - then two seasons ago Yamaha tried airfoils on the upper
    sides of their fairings

    Dustbin fairings were banned by the FIM in 1957.

  6. Sir hasn't looked at an old BMW R100RS, then, let alone anything since.
    Instability in x-winds, IIRC.

    Kawasaki ZX12R, although apparently they don't make much
    difference: http://myweb.cableone.net/toddshelton/aero.html

    Airflow/scoops - over radiators (power from cooler engine)
    and/or air induction (power from more air into fuel).

    my mandarin 1150GS has a canard beak - I've always wondered why it was
    fitted, downforce you reckon?
