Tmax any Good?

[Bluebottle]

It doesn't matter, Irev is sending you off on a tangent

A. You can place edges/surfaces downstream of separation that induce a more laminar flow and delay separation

B. It isn't what is happening anyway
The laminar lip etc don't claim to reattach flow or make it laminar
It is using a localised laminar effect to displace eddies
It also tries to align the flow to reduce the effect of sidewinds keep the quiet spot close to your helmet where it is needed

The physics is fine

Still, interesting to learn that Noah and the Wright brothers all road T-max

What a load of gobbuledegupe I'm trying one anyway if it work's great if it doesn't I'll
of become even more wiser than I am now and all that with only one big word.

As I said, it was great on my mk3 Tmax - though the original screen was so appalling anything was an improvement.

Only snag with the Lip is the Dual Lock sticky fixer things they give you to stick it to your existing screen. For one thing, you need a temperature of 70F for the adhesive to work, which isn't likely at this time of year, so you have to take the screen off and stick it on indoors.
But even then, on mine they failed without warning after around 6 months or so - I ended up screwing the lip to the screen using number plate bolts.

A complete misrepresentation of what laminar flow, and how it is achieved is the product infamously described as a Laminar Lip - You CANNOT achieve laminar flow by altering flow that has already detached from the surface.

The air flow up a windscreen has not detached until AFTER the lip.

Not possible: The AoA (angle of attack) of the screen exceeds the stall angle AND the airflow is never directly at the screen - you have an inherent sidewind effect caused by wind direction which will never be head-on for any length of time, apparent angle of deflection (as you roll the scooter from left to right you materially change the effect of the impact of air on the screen introducing spanwise flow where none exists or exaggerating or mitigating the effect where it already exists), and the impact of the air on the sides of the screen allows - in fact promotes a tumbling effect as the air pressure seeks to move from high to low, creating eddies and vortices.

Physically impossible for a screen or laminar lip to do what you state. Tuft yours, and prepare to learn something...

I have a Laminar lip on the maj. For what it's worth it has made a significant difference to the buffeting I used to suffer. It is significantly less than sans lip and I can trundle around town with the visor up. Thanks for listening and good afternoon to you all.
PS It is Rocket Science by the look of it.

I've ceased to care what it is or how it does it or how it doesn't do it - as long as it works!

[Funkycowie]

I like the buffeting, it adds extra thrill, but then I am weird like that

[smeghead]

I agree with Mr grumpy. I really don't care how or why it works, if it does then it does, simple really.

[Bluebottle]

I like the buffeting......

I like knowing how it works, lets you fix it, improve it, make it - thought it might help somebody else do the same
Plus I'd look dumb standing in the wind tunnel and get no more contracts.
I'll keep my gob shut next time

Sorry Irev, you're wrong about AoA > stall angle (cant be, its in negative alpha and it ain't a wing)
Someone less polite than me might say:

Tuft yours, and prepare to learn something...

I put on the GIVI AirFlo and the difference was ASTOUNDING! Buffeting gone, and both top speed and mileage increased due to the more aerodynamic frontal area...
