Fuel Requirement/Refueling

cbny
Fuel Grade
This Triumph motorcycle is designed to
run on unleaded gasoline with a CLC or
AKI octane rating (R+M)/2 of 87 or
higher. Federal regulations require that
pumps delivering unleaded gasoline are
marked 'UNLEADED' and that the Cost
of Living Council (CLC) or Anti-Knock
Index (AKI) octane
displayed. These ratings are an average
of the Research Octane Number (RON)
and the Motor Octane Number (MON).
In certain circumstances
calibration may be required. Always
refer to your authorized Triumph dealer.
Caution
The use of leaded gasoline is illegal in
some countries, states or territories.
Check local regulations before using
leaded gasoline.
Note:
• If 'knocking' or 'pinging' occurs at a
steady engine speed under normal
load, use a different brand of
gasoline or gasoline which has a
higher octane rating.

General Information
Oxygenated Gasoline
To help in meeting clean air standards,
some areas of the U.S. use oxygenated
gasoline to help
emissions. These gasolines are a blend
of conventional gasoline and another
compound such as alcohol. This Triumph
motorcycle will give its best performance
when using unleaded gasoline. However,
the following should be used as a guide
if you use any oxygenated fuels.
Ethanol
Ethanol fuel is a mixture of 10% Ethanol
and 90% gasoline and is often described
under the names 'gasohol', 'Ethanol
enhanced', or 'contains Ethanol'. This fuel
may be used in your Triumph motorcycle.
MTBE (Methyl Tertiary Butyl Ether)
The use of gasolines containing up to
15% MTBE (Methyl Tertiary Butyl Ether)
is permitted in this Triumph motorcycle.
Methanol
Caution
Fuels containing methanol should not
be used as damage to components in
the fuel system can be caused by
contact with methanol.
Caution
Because of the
volatility of oxygenated fuels, starting,
engine response and fuel consumption
may be adversely affected by their use.
Should any of these difficulties be
experienced, run the motorcycle on
normal unleaded gasoline.
