On-Road Motorcycle Surveillance Program
CARB has a need to collect more emissions data from the California on-road motorcycle fleet. Prior to 2019 CARB’s emissions factor model (EMFAC) had not been updated for motorcycle exhaust and evaporative emissions for inventory since 2000 prompting the need to test more current models to reflect new technologies and emission rates. A recent 2019 CARB motorcycle project provided emissions data from 13 on-road motorcycles ranging from model year 2008 to 2019 used to update the current EMFAC model.
A new surveillance program is being developed to start by spring of 2024 to continue testing to provide more current emissions data to represent the newer models and technologies of the in-use fleet. The objective of this program is to solicit and procure privately owned motorcycles from the in-use CA fleet and test them for exhaust and evaporative emissions in CARB’s Riverside laboratory. The makes and models of the motorcycles selected to be procured and tested would represent the highest DMV registration populations and technology groups. Data collected from this test program will be used to update base emission rates and evaporative emission rates in EMFAC.
