This SAE Recommended Practice applies to two- and three-wheel motorcycles intended for highway use. Vehicles commonly known as mopeds and mini-bikes are included in this vehicle category if they are intended for highway use.
This SAE Recommended Practice applies to two- and three-wheel motorcycles intended for highway use. Vehicles commonly known as mopeds and mini-bikes are included in this vehicle category if they are intended for highway use.
The motorcycle terminology presented herein addresses two-wheel single track vehicles, as well as motorized three wheel cycles. Although two-wheeled, single track scooters and mopeds are similar to traditional motorcycles, they have many characteristics which differentiate them from motorcycles, and while some terms will apply, this Terminology addresses motorcycles specifically, unless otherwise noted. Likewise, some three wheel cycles may have some similar design features and share components with motorcycle, the dynamics and handling of three wheel vehicles differs from two wheel, single track motorcycles.
This SAE Recommended Practice provides uniform definitions for various types of motorcycles, their components, and basic characteristics. The various classes of vehicles defined in this report include only those which are intended at least partially for public road use and excludes vehicles which do not meet common legal requirements for public road use.
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the sound levels of motorcycles under stationary conditions. This test will measure primarily exhaust noise and does not represent the optimum procedure for evaluating total vehicle noise. For this purpose, SAE J331 or SAE J47 is recommended.

This document establishes the test procedure, environment, and instrumentation for determining the sound levels of motorcycles under stationary conditions. This test will measure primarily exhaust noise, but does not represent the best procedure for evaluating total vehicle noise. For this purpose, SAE Recommended Practice J331a, Sound Levels for Motorcycles, or SAE Recommended Practice J47, Maximum Sound Level Potential for Motorcycles, are recommended.
