Scooters and air pollution

Hello,

I read that the Yamaha Majesty had a catalyctic converter as part of the muffler hence the fairly large size.
One could think that the same would be true for the Burgman 400 and 650.
Has anyone ever seen test results of exhaust gasses analysis? Do we do our share for a better environment or do we pollute just as bad a a lawn mower or snow blower?

Please help
Thanks


I didn't find the right solution from the Internet
