There is a schematic layout of the emissions system on my bike, a 2011 Moto Guzzi, as a sticker under the seat, so there is at least on manufacturer providing this information for roadside law enforcement. It is possible that the OP's charge may be related to the EVAP system and not the catalytic system.Cars have a big label under the hood describing the major components of the emission control system - I can't recall ever seeing such a thing on any motorcycle.

The cop said in reply "When someone has a muffler that is too loud, we just write em the three tickets now, $110 noise, $110 muffler, $365 emissions. If you have a cat, or it didn't come with one, they will dismiss that part in court, but I'm not an expert, I'm just saying most aftermarket systems dispose of the cat."
(P.S. The cop said as soon as he walked up to him, that their conversation was being recorded! First I've ever heard of this. Do you think I could request the audio tape with disclosure??)
