Catalytic Converter
186 Technical Information
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.
Follow these guidelines to protect your
motorcycle's catalytic converter.
• Always use unleaded gasoline. Leaded
gasoline will damage the catalytic converter.
• Keep the engine in good running condition. 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.
