Emissions regulations are established by the California Air Resources Board (ARB) and current motorcycle standards, which have been applicable since 2008, are harmonised with the Federal regulations.  The standards provide limit values for HC and CO, for engines of 50 to 279 cc, and HC + NOx and CO, for engines of greater than 280cc.  The HC + NOx limits for the latter group are applied on a corporate average basis.
