Highway Motorcycle Certification Requirements

This page last reviewed October 10, 2013

This page provides a list of emission-related regulations, test procedures, Manufacturers Advisory Correspondences (MACs), and related documents applicable to highway motorcycles (HMC), also known as on-road or "street" motorcycles, and is primarily for the interest and needs of manufacturers and others that are required to obtain certification from ARB. For more public-oriented materials, please visit our On-Road Motorcycle Regulation page.

Please sign up to the new Mobile Source Mailouts and MAC list server. By doing this, you will be notified when a new Mobile Source Mailout (e.g. proposing a new rule or amending an existing rule) or MAC (e.g. providing ARB's policy decisions and interpretations of the regulations and test procedures) has been posted to the Mobile Source Mailouts or MAC webpages. These email notices can replace any of the mobile source hard copy mailing lists you may already be on.

EPA Verify Not Forwarding Motorcycle (ONMC) and Off-Highway Recreational Vehicle (OHRV) Data To ARB E-Cert.

California’s application for certification of ONMC and OHRV consists of two parts: (a) emission data and descriptions of the vehicle, engine and emission control systems (data/descriptions), and (b) supporting information such as emissions label format, warranty, adjustable parameters and anti-tampering methods, etc.  The manufacturer uploads the data/descriptions to the U.S. Environmental Protection Agency’s (EPA’s) Verify system, which automatically forwards such data/descriptions to the Air Resources Board’s (ARB’s) E-Cert system.  The manufacturer uploads the supporting information to the ARB’s Document Management System (DMS) separately.  Upon staff’s review and determination that the data/specifications and supporting information meet all certification requirements, ARB will issue an Executive Order.  New ONMC and OHRV must be covered by an Executive Order to be legal for sale into California.

For the past two weeks, ARB has not been receiving E-Cert data from EPA.  There was a maintenance issue that prevented EPA from forwarding Verify data/descriptions to E-Cert from about September 25, 2013; ARB staff was about to resolve this issue with EPA when the federal government shutdown happened.  Since the federal government shutdown began, the Verify system has not been forwarding ONMC and OHRV data/description to ARB’s E-Cert system.

This notice is to advise manufacturers of an interim certification process for applications that were/are submitted on and after September 25, 2013 and for which the manufacturer needs to have an Executive Order in the next thirty days in order to support its marketing schedule.  To receive an Executive Order under these circumstances, the manufacturer may use the DMS to provide the data/descriptions that it normally submits into Verify.  Such data/descriptions may be submitted as a .pdf, MS Word or Excel file in the same workflow as the engine family specific workflow. When complete and valid data is received, ARB staff will be able to process the application. If you have any questions please contact your ARB certification representative. We apologize for this inconvenience.
