A thought to people who like riding with their visors up. The standard for a motorcycle helmet visor (VESC-8) calls for it to withstand a direct hit from a 1 oz steel ball bearing fired at 120mph without breaking or detaching from the helmet. I may, on occasion, crack mine open for a little airflow, but any time I'm moving more than 20mph, I want it between me and the world... and I've taken to carrying / wearing ballistic safety glasses in clear and tinted. They're cheap enough I don't get upset when I forget them somewhere.

All that said- yesterday I had my visor cracked about an inch and took a bumble bee to the face at about 50mph. FOOKING OW. (Riding the FJR- with windshield about halfway up. How the hell do bugs a) know they have a shot, and b) make that gap?)
Interesting, I didn't know that about helmet visor standards!
I have hit enough things right in the visor that I personally don't ride with it up either (unless stopped). It's incredible how much energy a little speed will give a small object. I hit a pretty good size bird (might have been a duck?) right in the middle of a cockpit windshield going at least 400 knots (~460 mph). (Its fairly common to hit birds near airports, but going a LOT slower, this was at higher altitude and very unusual) Inside the cockpit you could feel the concussion through to your bones, like the shockwave of an explosion. Thing just popped like a brown water balloon on there, not even a crack. Must be the toughest part of the airplane.

I dunno... ...but they are pretty damned good at it.

Maybe it's just persistence?

I had a buddy from Iceland, big bastard named Magnus Bjarneson, out on a city tour.

While doddling through a school zone, he suddenly jumped off the back of the bike!!

I stop, and there he is, cursing loudly and wrestling a hornet in front of the horrified children.

It had flown into his helmet; stung him 3 times.

Luckily the cursing was in Icelandic, but still really funny for all observers.

Works a treat. Not cheap I know but worth it IMHO.

Not quite so funny for the participant...

I had a bee and a wasp come over the windshield of the Aprilia, bounce off the tankbag into my Arai, and ricochet off my sunglasses. The wasp was trapped between my left eye & sunglasses, the bee was back by my right ear.

At that point I broke two world records: Shortest stopping distance from 70mph, and fastest removal of a motorcycle helmet.

Depending on the order you performed these actions, you might have set an additional record.....

I may have tied that record yesterday, except I was on a track doing a fair clip over 70mph when the bee came in. (Again, how do they do that?)

I got the helmet off and he (She, technically) was busy stinging the crap out of my helmet liner by my right cheek.

Get a dark yellow shield, you will never go back. They work great in bright light, rain, and are suitable for night riding. They bring out the contract so if t=you ride tree lined roads, they work like magic when riding in and out of shadows.

Shooters and Pilots learned the lesson years ago, Moto riders seem to be behind.

Um, you may want to revisit you claim on the impact test for VESC-8.

Arai dark tinted shield with Maui Jim sunglasses sun up to down. If it rains I pull the glasses. At night I put a clear on or flip the tinted shield up and use clear safety glasses.

UV light from the sun is one of the worst things for your eyes...other than a rock at 65mph.

Do the inner drop down visors meet the VESC-8 standards ?

I recently bought a Scorpion 900 Transform helmet. The pop down visor is dark and is pretty darn good optically, I wear prescription glasses (transitions) and wanted a helmet that went on over them easy. This one does pretty well.

Its seems fairly quiet, the drop down mechanism works, its a flip up front style so I can put it on without taking off my glasses. Ventilation is good as well. It also has the pocket for the Bluetooth radio module on the side.

It must be true, I read it on the interwebz. OK, I was wrong- 1.56 oz (~40g) @ 20mph ("free fall from 14 feet")... 1.77 Joules

OTOH, Snell's is tougher- 1g @ 500kph... 9.45 Joules.

I wear prescription glasses (never learned how to wear contacts). On a regular commute, I use my Nolan N44 with an integral tinted inner visor; it's really convenient to flip it up if it suddenly gets dark (like going through tunnels).

There's a regulation to how dark these integral visors are allowed to be though, which is annoying (since, IIRC, regular tinted visors don't have the same limit). For really bright days (and when I know we won't passing through tunnels), I prefer sunglasses.

I like the AFX-39 DS helmet which has an external sun visor (dark) which goes over the clear visor and can be used with the shade peak in place as well. Goggles also can go under the clear shield and external sun shade. I have had this helmet for over a year now and it's a favorite and not too much $. There is a new version out now AFX-41 which has an inner sun shade. I prefer the FX-39 external as I can wear my clear goggles and flip down the visor/shade combo for a short time if needed.

I run an icon Airmada, if I'm going on a trip I carry the stock clear and the "normal" dark tint one (see avatar)... the dark tint one, no idea how it works, but I can ride direct into the sun with it...
