I've not seen any mention of this yet, but don't know if any other Scrambler riders have experienced excessive, resonant helmet noise. Both my wife and I noticed it instantly on her bike, and on anything other than table top smooth roads gives a real drumming noise through the helmet, similar to what you might get if you just crack open the front windows on your car at speed.

My personal opinion is that it is a combination of the block pattern tyrs and harsh suspension, but I'm surprised that I haven't seen it mentioned anywhere yet. We both use ear plugs and wear Arai helmets. Has anyone else experienced this?

Do you wear earplugs? I noticed on one helmet that the helmet was being jarred over the bumps and rubbing my earplugs making a drumming noise.
Yes, we always wear earplugs, I can't even ride to the shops without them. That said, I have worn the same type of disposibles for years and my wife has custom moulded ones. The Arai's are also cut away at the ears to give more space, so I don't believe this is the issue.

Sounds like a helmet issue regardless of the bike...
It is possible that it is the helmet, but it is unusual in that I have owned over seventy bikes and never experienced this level of noise on another bike. We currently have six other bikes (most naked or with a small flyscreen) between myself, wife and daughter, and the Scrambler is the only one producing the noise.

Change your helmet ;)
Easy said, but I've used Arai for over 25 years now, and always been very happy. I know they are not necessarily the quietest or lightest helmet, but they are all day comfortable, well made and fit well. I've tried others, but have always come back to Arai.

Just picked up my Urban Enduro today and rode 60 miles home. I noticed that same thrumming once I hit some speed on a country road that wasn't that smooth. I have a Schuberth C3 and I was wearing standard soft moldable earplugs. Different road surfaces made a difference to some extent but by the time I got about 40-50 miles on the bike it seemed less noticeable. Same sort of thing happened once when I got a new 80/20 Kenda front tire on my Triumph Tiger 955. I think it will get better as the sharp edges on the tire wear a bit AND I reduce the tire pressure just a few pounds.

Hi Joe I have a classic only covered 500 miles, prior to that I had an MV Augusta using my Arai RX7 on both bikes I have not noticed any increase in noise level.

Updated observation - When wearing basic 'Macks' moldable earplugs, I get the resonant thrum, like the open window of a modern car. If I don't have earplugs in, not noticeable and the road and wind noise is actually less than on my Tiger 955 or my Ural Tourist. The resonant frequency gives me a headache after about 20 minutes. No plugs, no bad noise, no problem. I now have 200 miles after a week with my UE. Love the bike BTW.

Thanks for the input, good to know that it's not a consistent problem. It's still there on my wife's bike for both of us. I wear disposable ear plugs always, and my wife has custom moulded plugs. The bike has got better, and it's now mostly noticeable at lower speeds over less than perfect roads. personally, I'm convinced the problem will go when we finally get round to sorting the front forks.

I have 2 bikes, 1 scrambler and one older road bike and notice that I get a real high frequency vibe in my helmet sometimes about 130km/h on the scrambler only. I've ridden with this Helmet (Nolan) for a couple of years and it's only happened since I got the scrambler. It's a real fast shimmy that resonates at a certain speed and affects my vision a bit. Strange.

I have a few helmets...Arai Corsair V seems to be the best for aerodynamics on naked bikes. Have been well into the 200Km/h range on multiple bikes (Scrambler included) and there is no "unusual" noise. I have been paying attention to see if I can hear the tires on the Scrambler and its faint at best (until the wind noise takes over).

Ive had bikes running Conti TKC80's and there was a noticeable amount of road noise and vibration from those at speed...especially when they were closer to new.
