Proposed Amendments to On -Road Motorcycle (ONMC) Emissions Standards and Test 
Procedures and adoption of new provisions relating to ONMCs under Division 3, Chapter 
1, Article 2 (Approval of Motor Vehicle Pollution Control Devices) under Title 13, California 
Code of Regulations  (collectively "Proposal") will significantly increase the prevalence of 
zero-emission motorcycles (ZEMs) in California while also reducing emissions from 
remaining motorcycles that are powered by internal combustion engines (ICE) by greatly 
harmonizing with more stringent European Union 5 (Euro 5) exhaust emissions standards, 
proposing more stringent evaporative emissions standards, and adopting additional on -
board diagnostic (OBD) requirements beyond Euro 5. The Proposal will drive the sales of 
ZEMs to 50% in California by the 2035 model year, thereby reducing greenhouse gas 
(GHG) and smog forming emissions, while also reducing smog -forming emissions from 
newer ICE motorcycles.  
CARB will conduct a public hearing on 25 January 2024 at 9 am Pacific Time  to consider 
approving for adoption the proposed amendments to the On -Road Motorcycle (ONMC) 
emission standards and test procedures and adoption of new provisions relating to ON MCs 
under Division 3, Chapter 1, Article 2 (Approval of Motor Vehicle Pollution Control Devices) 
under Title 13, California Code of Regulations (collectively "Proposed Regulatory Action").
