(Too) Loud sound systems

When I had my Honda ST 1300 I tried the earbuds / iPod thing .
When I did manage to keep the ear buds in place after putting the helmet on I soon found it too distracting. I’m with grandpaul on
this - I’m out to ride and enjoying all the sensations that the bike has to offer .

Crecendo Foam Earplugs​

The only things I put in my ears when riding are earplugs - I found out at quite a late age that noisy helmets and high-ish speeds do really bad things to ones hearing.
Now adays, if Im going to be riding on a motorway, I always use earplugs. It's so much nicer!

I used to work in the audio industry, and my last real job involved production of custom earplugs with acoustic filters, the idea being that you hear the full spectrum of sound, just at a lower level. Works really well, and is a vast improvement over the cheap universal 3M foam plugs that I started using. They remove most of that head-in-a-bucket feeling you get from the 3M types.

Dynamic Ear Company in the Netherlands do a very good set of universal acoustic foam plugs with filters and vents for a very reasonable cost (especially compared to a set of custom fits!) under the brand name Crescendo Foam Earplugs.
And no, I don't work for them nor do I get paid, I just don't like people damaging their hearing!

These seem to be the ones I was thinking of, but they don’t seem to offer different attenuation levels. Might be worth while asking them though.

In the 1960s, the way to get a four-stroke really going was to use a race cam with a megaphone exhaust. In later years , many motorcycles have Exup which is supposed to increase torque. I suggest what it does is to quieten the exhaust sound without losing too much power. The exhaust system on my bike works very well, but the noise is horrendous. My local race circuit has given motorcycles the flick. There is another circuit about 400 Km up the road, however there is a declared noise limit. I still want to make an onboard video just to document what the bike does. For me road racing has only ever been about the dog-fight and developing the bike. My Seeley 850 is a lot different than any other race bike I have ridden. I never believed it could be so effective. The steering geometry is extremely important. I found this video which is relevant but about 40 MPH slower. The bike appears to be neutral handling - on a bike like that, if you brake hard enough to depress the forks - the bike usually tends to run wide faster. With my bike, there is no counter-steering requirement.
