Fuel Requirement/Refuelling

Fuel Grade

P b
This Triumph motorcycle is designed to run
on unleaded gasoline with a CLC or AKI
octane rating (R+M)/2 of 89 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 rating is also displayed. These ratings
are an average of the Research Octane
Number (RON) and the Motor Octane
Number (MON).
Caution
In all countries except Australia and New
Zealand the exhaust system is fitted with a
catalytic converter to help reduce exhaust
emission levels. The catalytic converter can
be permanently damaged if the motorcycle
is allowed to run out of fuel or if the fuel
level is allowed to get very low. Always
ensure you have adequate fuel for your
journey.
Caution
The use of leaded fuel is illegal in most
countries, states or territories. Use of
leaded fuel will damage the catalytic
converter (if fitted).
General Information
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.

Oxygenated Gasoline

To help in meeting clean air standards, some
areas of the U.S. use oxygenated gasoline to
help reduce harmful emissions.
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.
