The RD07 even has a fake slot just above the headlights, but it's

I imagine that opening this slot might create a similar effect.

I have a 99 RD07 I have noticed this slot but can see no use for it
other than for appearance. If you remove the blockage water will be
pushed up into the area behind the clocks and the tripmaster, can't see
this as a good idea. Perhaps some stylist thought of the idea, and then
an engineer veto'd the idea. I used to own a VFR750FP this has a slot in
the screen which does alleviate turbulence.

Subject: (XRV) Holes in the windscreen?
Date: 30 April 1999 20:17

Hi everybody,

Some time ago I read an article in a German bike magazine (don't
remember which one) about a way to minimise turbulences behind the
windscreen by drilling a few holes into the windscreen near the bottom
end.

Normally - and particularly at higher speeds - there's an obvious
difference in air pressure between both sides of the windscreen, making
the air "fall" down immediately after streaming over the top edge, i.e.
towards the area of lower pressure. This problem gets worse on bikes
with a large distance between the windscreen and the rider's head, like
the @.
The a.m. holes egalise the pressure difference, so that the air is not
sucked downwards in front of the rider's head or chest area.

Of course one must install some kind of barrier behind the holes to
prevent water from entering the cockpit when riding in the rain.

Actually, quite a few newer bikes have this kind of additional air
intake in the lower part of the windscreen (a narrow slot rather than
holes).

The RD07 even has a fake slot just above the headlights, but it's
covered from the inside by the lower edge of the windscreen.
I imagine that opening this slot might create a similar effect.

Oh, and here's my question: Has anybody ever tried the above on an @?

Regards,
Axel.
