On-Road Motorcycle Regulation
This page last reviewed May 3, 2012
Background
ARB adminsters a program for reducing emissions from highway
motorcycles. Authority for controlling emissions from highway
motorcycles is established in sections
1958 (exhaust) and 1976 (evaporative), title 13, California Code
of Regulations (CCR). The California exhaust emission test procedures
are adopted from the U. S. Environmental Protection Agency's (U.S.
EPA's)
exhaust test procedures in title 40, Code of Federal Regulations, Part
86, subparts E and F.
Requirements for highway motorcycle certification include provisions from demonstrating compliance with
the applicable emission standards using specific test procedures, as well as emission labeling and warranty obiligations.
What's New...
A public workshop to discuss a draft proposal to regulate evaporative emissions from Off-Highway Recreational Vehicles (OHRVs) and On-road Motorcycles will be held on April 20, 2010 in El Monte. The workshop documents can be found here: Workshop Notice, Agenda, Proposed Regulation Summary, Proposed Test Procedures Summary ARB PresentationA public workshop discussing future evaporative control measures for on-road motorcycles was held on January 15, 2009 in El Monte. The presentation can be viewed here: On-road Test Plan Presentation.
In January 2009, ARB proposed regulatory amendments involving highway motorcycle aftermarket critical emission control parts.

1998 Amendments
ARB identified highway motorcycles as a potential
source of air pollution which could be reduced cost-effectively in order to satisfy requirements of the 1994
California State Implementation Plan (SIP). The SIP required reductions in air pollution from a wide variety of
mobile, stationary, and area-wide sources.
