nonomo is an international movement against motor noise — starting with the loudest, most avoidable offender: motorcycles and mopeds modified to be as loud as possible.
Environmental noise is one of the most under-addressed pollutants in cities today — and modified motorcycle and moped exhausts are among the loudest, most deliberate sources of it.

There is a sound that follows you indoors. It rattles windows at 11pm and wakes children who did nothing to deserve it.
It is not traffic. It is not the city. It is one motorcycle, or one moped, with a pipe modified to be as loud as possible, ridden by someone who has decided that everyone within four hundred metres will listen to their engine whether they want to or not.
We are not anti-motorcycle. We are not anti-rider. We are against the small, deliberate choice — an aftermarket exhaust, a removed baffle, a twist of the throttle outside a bedroom window at midnight — that turns a private vehicle into a public disturbance. That choice is not freedom. It is one person's convenience purchased with everyone else's peace.
Motorcycles and mopeds are a disproportionate part of the noise problem — not because there are more of them, but because a single loud motorcycle can be louder than dozens of ordinary cars combined, and because so many riders modify their exhausts specifically to be louder than the law allows. Legal limits already exist in most countries, generally somewhere between 80 and 95 decibels depending on jurisdiction. Modified pipes routinely blow past them. Enforcement, until recently, has mostly meant nothing at all.
That is starting to change, and it proves the fight is winnable. Cities are now measuring and fining noise automatically — proof that the tools already exist. What's been missing is the will to use them everywhere, consistently.
nonomo exists to build that will. We are starting small and specific, not broad and vague: loud motorcycle and moped exhausts, in named streets and named cities, backed by the ordinances that mostly already exist and mostly go unenforced. We are not asking anyone to invent new laws first. We are asking cities to enforce the ones they have, and asking riders to accept a simple standard: modify your bike for performance, for comfort, for style — not to make yourself impossible to ignore.
What we're asking of you: Sign the pledge. Tell us where the noise is worst — the street, the hour, the pattern — so we can point at something specific instead of complaining in general. If you're a rider who agrees loud pipes aren't a personality, say so publicly; you are the most credible messenger we have.
We are not trying to silence the road. We are trying to make it possible to sleep with your window open, hear a conversation on a terrace, and walk down a street without being ambushed by an engine that was made loud on purpose. No noisy motors. That's the whole idea. Join us.
No new technology or science is required. Cities that decide to act already have what they need.
