Gave it a wash. Not really. Too lazy. Gave it to a local West Oz mob, cleanride.com.au. Nice job. Shiny.

I picked up a neotech II recently and rode across OZ and back with it in Sept. It's a good flip face. It is designed to integrate a Sena bluetooth kit.
Nice quality speakers fit into recesses in the earpieces. The controller fits in a recess in the helmet. Under a waterproof rubberised panel on the LHS are the buttons to run the thing.
Nothing hanging off the helmet and you don't even know it has a Sena kit.
I'm not into noise when I'm riding but the phone was useful. If listening to music it's a nice quality sound but I doubt much good over 100-120 k's.

My Neotech has way more wind noise than the Multitech I had before it. I tried wearing earplugs but hate hearing nothing more than the wind noise.

I reckon the white noise of 100s of 1000s of km from wind in the ears moto riding has damaged my hearing more than anything else I've subjected my poor ears to, including decades of playing drums in loud rock bands! Once you wear earplugs, then try riding at speed without them, like forgetting to put them back in after a fuel stop, you realise just how loud tiring it is. Takes some getting used to. I found my speed perception coming into corners was somehow different.

For me most hearing damage was caused by being involved in drag racing for many years, most specifically listening to the Top Fuel engines being warmed up in the pits
Never heard a better sounding engine ever including our own 180 degree triple race engines
The first time I heard, or more correctly felt that was in 1976. I was on my first big ride and was staying on The Gold Coast and a couple of times the promoters of the Surfs Paradise Drag way started up a couple of funny cars in a petrol station right on The Strip.That created some crowd.So I went to a meet.You could feel the throb of the engines in your chest at full noise,the only couple of things comparable were the low fast passes of Fighter Jets at The Bicentennial Air show and front row at a Deep Purple concert.I like LOUD.

It's incredible that they can get that sort of power out of a V8 engine. I noticed in the video that sweetas posted of the 11,000HP engine being built (in the "Cool videos" thread) that it didn't appear to have any cooling system. So I don't reckon those top fuel engines can run for more than a few seconds at a time.
that is correct Cam, fuel engines as do a lot of the big horsepower drag engines are solid alloy so no water jackets
but the Nitro load itself helps to cool the engine as they use around 98% of the combustion chamber for fuel volume, only 2% is left for oxygen
though the Nitro carries its own oxygen molecules so it does not need much extra air
did you know that the flames being emitted from the exhaust pipes is actually the hydrogen in the atmosphere igniting due to the extreme heat being generated

I've never been to a drag race meeting. Maybe I should put it on the bucket list.

There ain?t nothing beats the sound or horsepower of a Triple engined Breganze 750 Drag Bike on Nitro. 99% fuel combustion as well. Talk about leaving the latest Jap bikes for dead down the quarter... and the wheelstands..

I've always wanted to go to at least one big-time drag meeting with top0fuellers. Have checked out a few vids on Youie and they used to show US drag racing on one of the TV channels late at night (Ch ONE?). The guys dialling in the fuel mixture on the start line used to blow me out. And the slowmo's of the first 100m when the blower would eat itself (kaboom!), belts and tyres twisting totally out of shape. Pretty incredible stuff. And when they go off course and crash, it's not at all pretty. The drivers are exposed to considerable risk.
The supercharger on that ARMY build looks like it would crank about 20 bar!! Who needs 4-valve heads?! Pretty handy conrods and pistones to withstand that sort of horsepower. They probably have a max possible time at full noise without self-destructing about 1.2 sec longer than their expected time for the quarter!!

Arrrhhh that's nuthin. The Chinese have just built an engine that develops 100 million degrees C. Only runs for about 10 seconds but.
My ears are stuffed from using my 30-40 and 25-06 without ear protection.
