CONCORD, N.H. – A bill to fix motorcycle noise problems is roaring into the House for a vote next week.

A new compromise would change the testing standard for motorcycle exhaust rather than lower the permitted decibel level as the original bill did. Amendment supporters say the current noise test was designed for off-road motorcycles and is inaccurate and impractical for quick, roadside tests. Because police aren’t able to accurately test for noise violations, some motorcyclists have continued to ride the loud bikes that residents complain about.

The new test from the Society of Automotive Engineers International allows a police officer to test a bike propped on a kickstand.

The bill allows for 92 decibels while idling and either 96 or 100 decibels while revving the engine at a certain speed, depending on the engine type.

The current law allows for 106 decibels at 2,800 revolutions per minute. The higher level reflected the inaccuracy of the testing method at the time it was instituted, said Candy Alexander, vice president of the New Hampshire Motorcycle Rights Organization.

The new test with lower noise levels reflects the increased equipment accuracy and current industry averages, Alexander said.
