Fuel Requirement/Refuelling; Fuel Grade - Triumph Trophy Handbook

General Information

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 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 rating is also displayed. These ratings
are an average of the Research Octane
Number (RON) and the Motor Octane
Number (MON).
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.

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.
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 generally higher volatility of
oxygenated fuels, starting,
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.
