Only 2 places in the US I've heard of that requires smog testing for motorcycles are parts of Pima and Maricopa counties in Arizona. Since the first year for Bonneville Americas was 2002, and few Arizonans post here, you won't see a smog test happen until probably 2008(June). I'll let you know then.

That's IF I even have to go through it. A law has been passed expempting motorcycles, and some other vvehicles in Pima County, but it still has to get by the EPA.
