Oil Specification And Grade; Cooling System; Corrosion Inhibitors - Triumph Trophy Handbook

Oil Specification and Grade

Triumph high performance fuel injected
engines are designed to use 10W/40 or
15W/50 semi or fully synthetic motorcycle
engine oil that meets specification API SH (or
higher) and JASO MA, such as Castrol
Power 1 Racing 4T 10W-40 (fully synthetic)
engine oil, sold as Castrol Power RS
Racing 4T 10W-40 (fully synthetic) in some
countries.
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 to the required specification. The
use of these oils may cause instant, severe
engine damage.
Maintenance and Adjustment

Cooling System

cbob
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 anti-freeze,
and has a freezing point of -31°F
(-35°C).

Corrosion Inhibitors

To protect the cooling system from corrosion,
the use of corrosion inhibitor chemicals in the
coolant is essential.
If coolant containing a corrosion inhibitor is
not used, the cooling system will accumulate
rust and scale in the water jacket and radiator.
This will block the coolant passages, and
considerably reduce the efficiency of the
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.
