Harley has been putting a catalytic converter on their bikes since 2010.
(2009 in California). They also had them in some models a few years
before that as well. No smog inspection on bikes in MA but I think in
some states like CA, there is.
Actually, MA did away with the tailpipe emission test for all vehicles
since 2008 as long as the vehicle has the OBD readout capability. The
computer just checks for recorded faults.
