CATALYTIC CONVERTER
This motorcycle is equipped with a catalytic converter.
The catalytic converter contains precious metals that serve as catalysts, promoting chemical
reactions to convert the exhaust gases without affecting the metals.
The catalytic converter acts on HC, CO, and NOx. A replacement unit must be an original
Honda part or its equivalent.
The catalytic converter must operate at a high temperature for the chemical reactions to take
place. It can set on fire any combustible materials that come near it. Park your motorcycle
away from high grasses, dry leaves,or other flammables.
A defective catalytic converter contributes to air pollution, and can impair your engine’s
performance. Follow these guidelines to protect your motorcycle’s catalytic converter.
• Always use unleaded petrol. Even a small amount of leaded petrol can contaminate the
catalyst metals, making the catalytic converter ineffective.
• Keep the engine tuned-up.
• Have your motorcycle diagnosed and replaced if it is misfiring, backfiring, stalling or
otherwise not running properly.
