Catalytic Converter - Honda CRF1100A 2021 Owner's Manual

Catalytic Converter

This vehicle is equipped with two three-way
catalytic converters. Each 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 gases 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.
Follow these guidelines to protect your vehicle's
catalytic converters.
Always use unleaded petrol. Leaded petrol will
●
damage the catalytic converters.
Keep the engine in good running condition.
●
Have your vehicle serviced if your engine is
●
misfiring, backfiring, stalling, or otherwise not
running properly, stop riding and turn off the
engine.
