Back when I had my Honda CB 350F in the 1980's, I asked my "Yoda Mechanic" if I could get a catalytic converter for my early 1970's vintage motorcycle. He looked at me funny, as if to say "Crazy, you are".

This thread made me look for emissions friendly motorcycles and I found this (protptype only) :

Compressed Natural Gas engine
- 230 cc one-cylinder natural gas engine, CVT gearbox and differential.
- Pmax 12.5 kW at 8600 rpm, max. torque 15.5 Nm at 6300 rpm
- CO2 emissions 59.5 g/km (test bed values, corresponding to 2.4 l petrol equivalent).
