Aerodynamic Conflict. Helmet/bike.

Helmet buzzes exactly on the ton. The helmet is a good fit but vibrates my head at the said speed. I need a screen. Some screens look cool, some look like sht. Can anyone recommend a cool one that would alter the aerodynamic?

Also, while you're here, can you recommend a helmet for a fat head? I had the X Spirit mk1 not out of choice-it was the only one fitted me-everything else was too small. Same with the X Spirit mk2. The largest sizes in other brands don't even slip on my head. Much appreciated.

Can't help with the buzzing because there are so many buzzes and rattles on my old piece of shit that I'd never notice another one! I'm also a deef old c*nt who wears earplugs to somewhat fruitlessly retain what little remains of his hearing!

I can advise on the Huge Melon issue. Try an HJC. They are made for deformed freaks like me who look like the fucking Mekon, (You're far too young to know who the Mekon was but Google up Dan Dare and you'll soon find out.). I've currently got a Shark modular helmet that I love but it crushes my specs into my head when I have the chin piece down and is only *Just* big enough for my scone. I think my next one will be another HJC.

The way I test helmets is to go to the shop and try them on with a good book, or my iPad, and sit with each one on for half an hour while having a good read. If they are going to hurt they'll hurt while you are reading, usually. The shop assistants think you're bonkers and you find yourself being pointed at and discussed quietly by people but one of the only good things about getting old is you really, really, don't give a fuck! Very Happy

MRA Vario screen and Shoei RF1200 Helmet, quietest helmet I've ever had.

Option: sensible.
Option 2: do what you want.

I acted with a guy in London who would recite his lines from Shakespeare on a packed tube train in the morning. He had a thunderous voice. You would have noticed. A lot.

HJC, MFA Vario, Shoei RF1200. Got it. The problem is really vibration rather than sound. The helmet resonates in a strange way and comes on at 100mph. It's high frequency and instant. Back off the throttle it goes. Got to be worth the vario screen - it doesn't look sht. I'm sending a Virtual Beer to you both.

Go faster than 100, sorted or not?

750

can't remember. It's been raining for so long. I think it may ease slightly but at those speeds there's buffeting anyway.

This will keep you busy reading about windscreens for a while...

Put a piece of thick tape on a corner of the face shield. It's probably the shield vibrating. Idea

My fairly new AGV (Skyline) is starting to be noisy and I know it's the visor...
I might try some felt material around the opening and see what happens.
That helmet was quiet when new and I'd like to get it back that way as I like the built in visor and love the quick release.

This is brilliant.

If you could find the sweet buzzy spots for other mph markers, e.g., 35, 55, and 70 or so, for the US market, at least, you'd make a mint. Sort of a poor man's aural version of a heads-up display. jocolor

an "ear up" display?

Montanarolo Posts : 21 Join date : 2014-11-19

Thanks for your input Bill.

Carver: The problem is not the visor, however. I flip the visor up and down-turn my head side to side. The vibration is high resonance and powerful. It vibrates the visor and probably my eyeballs. This reminds me, I have to visit my friend who is suffering from a detached retina he got from what appears to be a bizarre sunbathing accident.

I will get an MFA Vario screen or similar - this will alter the aerodynamic feature. My friend though, well lounging in a pool in Crete is not without risk.
