octane rating requirement.

motorcycle:
Ethanol (ethyl alcohol) up to 10% by volume.
Petrol containing ethanol may be marketed
under the name Gasohol.
The use of petrol containing more than 10% ethanol
may:

Cause corrosion of the fuel tank.
Cause poor drivability.

OTICE
Use of blended fuels containing higher than
approved percentages can damage metal, rubber,
plastic parts of your fuel system.
If you notice any undesirable operating symptoms or
performance problems, try a different brand of petrol.

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 petrol. Leaded petrol will
damage the catalytic converter.
Keep the engine in good running condition.
Have your motorcycle serviced if your engine is
misfiring, backfiring, stalling, or otherwise not
running properly, stop riding and turn off the
engine.
