Catalytic Converter - Honda NM4 2018 Owner's Manual

Catalytic Converter

Catalytic Converter
This motorcycle is equipped with a three-way
catalytic converter. The catalytic converter
contains precious metals that serve as catalysts
in high temperature chemical reactions that
convert hydrocarbons (HC), carbon monoxide
(CO), and oxides of nitrogen (NOx) in the
exhaust gasses into safe compounds.
A defective catalytic converter contributes to air
pollution and can impair your engine's
performance. A replacement unit must be an
original Honda part or equivalent.

●
A poorly running engine can cause the
catalytic converter to overheat causing
damage to the converter or the motorcycle.
If your engine is misfiring, backfiring, stalling,

or otherwise not running properly, stop
riding and turn off the engine. Have your
motorcycle serviced as soon as possible.
