Hey Paul, it’s Mario met you when I was fundraising in Ballarat. Just thought to update you, I recently passed my permit last weekend and just picked up my R7 today, had the best night riding along the beachside of Brighton. Thank you for all the inspiration and knowledge. Keep up the amazing content 💪
What a great idea, it looks good too, reminds me of a gladiator helmet. There'll be lots of design suggestions and comments saying you should be doing this and that. But at the end of the day the difference is, you are doing it and they aren't. Keep it up I'm interested to see the design evolution, definitely makes a change from bolting on mass produced farkles.
I Love the exhaust sound on your Indian. Fairings on bikes are so hit and miss. I have a Victory Cross Country which are renowned for wind buffeting. After a lot of experimenting I found the Madstad bracket used with the factory fairing improved the buffeting by about 80%. I believe the after market fairing with the flared top will improve it even more. Unfortunately they are all come from the US and with the AUD = USD $ exchange coupled with the shipping cost makes it a very expensive purchase for something not guaranteed to work.
The best little fairing i had was on a 1981 XS 1100 Yamaha Sport RH. ( all black model ) . It had a small kick up at the top of screen that pushed air up and over. I could feel only slight turbulence on top of helmet . Over the years and on various bikes I intended to copy it but never did. Was not a big size but i believe modification of the principle should give results. Just a thought. Hope it all works out well for you.
A great idea, and a wonderful creation. If you could tape some pieces of wool on the front of the fairing and film the airflow? That is how the old time aerodynamicists did it....
On your original sketch, you assumed that air was rising up the front of a typical blade screen becoming turbulent at the top. However, your second sketch ignores rising air and assumes that the lip will push all of the air in the opposite direction. Why make this assumption? I believe that most turbulence above and around any screen is due to the difference between positive air pressure in front of the screen and negative pressure immediately behind the screen. The larger the area of the screen, the greater this effect becomes. Honda tried to reduce this difference on GL1200 screens by introducing a through screen vent in an effort to minimise the pressure diffential.
Yeah that's a good point. I was thinking the air being directed downward would overcome the upward force of air but my assumption may be incorrect. Over the years on the bikes I've owned I've found negative air pressure and turbulence to be two separate factors. I've ordered screens with vents that have worked to relieved negative air pressure and that feeling of being sucked forward, but not necessarily the turbulence.
@BikesILike I'm an aircraft engineer. I'm just thinking that turbulence will be generated in the negative pressure area, also, the bolts and clamp possibly mess up any aero on the forward side of the screen anyway. It's an inexact science for anyone without a wind tunnel. Motorcycles are unaerodynamic already without a full streamliner body.
@markbright7845 No, I appreciate your feedback Mark, I really do. Based on your astute questioning, I went back and redesigned a new version to angle forward like a boat hull. Retaining the lip to direct the air down and away. But if the pressure differential is the root cause, it probably won't make much difference. I still want to do it just to see what happens. :) I'm now thinking a scoop at the bottom of the shield to direct a stream of forced air up the back of the screen might work to? 🤔 In which case, I could go back to my original screen and design a lower air scoop design for that. Hmmm... more thinking to do, as you can see I like experimenting.
Nice piece of inventive design. Reminds me of the snowplow on the front of a locomotive. Some of the faired Harleys use a similarly curved screen. Looking forward to bilfairing.2.
Smart idea, Klock Werks does this, kinda… on their flare windshields.
Great video dude!!
Thank you!

Awesome! Thank you and so good to hear Mario, it was a pleasure to meet you mate. R7... nice! Enjoy that new ride and always remember to ride safe! 👍
Thank you, keep going.
Please add a little grid of smoke streamers ahead of the fairing so we can see how the deflection and redirection is working.
Bloody good onya mate. Would love a small, neat and simple to fit fairing for the Forty-Eight .... and on a budget.
Cheers Locutius!

Very creative, maybe a slighty larger piece.
Cheers Jerry, I'm gathering together all your suggestions. ;)

Cheers Peter, I'll check out the Madstad Bracket.
Hats off to you, Paul. Curiosity, creativity and perseverance, combined with impressive 3D printing skills! Love it👍
Cheers RM! It's also a bit of fun. :)

Cheers Daryl. I too owned an XS 1100... or XS 1.1 as it was known around here. 😁
When I do photogrammetry of shiny elements, I use toothpaste or anything to make it matt, and clean after the scanning.
Good tip, cheers!
Add a few spikes and call it Triceratops :)
:)
Looks abit like a sheet metal spike for pedestrians m8
It's plastic
