Engine Oil Specification and Grade
(10W/40 & 10W/50)
Triumph's high
injected engines are designed to use
10W/40 or 10W/50
synthetic motorcycle engine oil that
meets specification API SH (or higher)
and JASO MA, such as Castrol Power 1
Racing 4T 10W-40
engine oil, sold as Castrol Power RS
Racing 4T 10W-40 (fully synthetic) in
some countries.
Refer to the chart below for the correct
oil viscosity (10W/40 or 10W/50) to be
used in your riding area.
Oil Viscosity Temperature Range
Do not add any chemical additives to
the engine oil. The engine oil also
lubricates the clutch and any additives
could cause the clutch to slip.
Do not use mineral, vegetable, non-
detergent oil, castor based oils or any oil
not conforming
specification. The use of these oils may
cause instant, severe engine damage.
Make sure that no foreign matter enters
the crankcase during an engine oil
change or top off.

Cooling System

To ensure efficient engine cooling, check
the coolant level each day before riding
the motorcycle, and top off the coolant
if the level is low.
Note
A year round, Hybrid Organic Acid
Technology (known as Hybrid OAT or
HOAT) coolant is installed in the cooling
system when the motorcycle leaves the
factory. It is colored green, contains a
50% solution of ethylene glycol based
antifreeze, and has a freezing point of
-31°F (-35°C).
Corrosion Inhibitors
Warning
HD4X Hybrid OAT coolant contains
corrosion inhibitors and antifreeze
suitable for aluminum engines and
radiators. Always use the coolant in
accordance with the instructions of
the manufacturer.
Coolant that contains anti-freeze and
corrosion inhibitors
chemicals that are harmful to the
human body. Never swallow antifreeze
or any of the motorcycle coolant.
