Decibels, dB tests, and staying street-legal

Loudness is measured in decibels, but a single number rarely tells the whole story — readings depend on RPM, distance, and test method.

Why ranges, not single numbers

Owner-measured figures vary with baffles, elevation, and microphone placement. Honest guidance gives a range with a confidence level, not fake precision.

Legality is local

Noise limits and inspection rules differ by country, state, and city, and they change. Treat any 'street-legal' claim as a starting point and verify your local limits before riding on public roads.

Dezybel's approach

Reports classify legality risk as likely street-safe, verify locally, risky, or track/off-road only — and always tell you to confirm locally. We never make legal guarantees.
