Wear Protection for Motorcycles.
2 MOTORCYCLE PRODUCTS
Motorcycle Oils are formulated with premium synthetic base stocks and high
performance additive technology that provide superior multi-functional benefits
for the special requirements of motorcycle applications. These independent and
exclusive AMSOIL formulations provide second-to-none viscosity protection for
hot-running American and foreign motorcycle engines, transmissions and primary
Synthetic Motorcycle Oil (MCV) is recommended for Harley-Davidson, Buell, KTM,
Ducati, BMW, Aprilia and Triumph motorcycles calling for a 15W-50 or 20W-50
viscosity, providing superior protection in engines, transmissions and primary
Synthetic Motorcycle Oil (MCF) is recommended for Honda, Kawasaki, Yamaha,
Suzuki, BMW, Husqvarna and KTM motorcycles calling for a 10W-40 or 20W-40
viscosity, providing superior protection in engines and transmissions. AMSOIL
10W-40 Synthetic Motorcycle Oil (MCF) is also an exceptional product for any
transmissions requiring a 10W-40 lubricant.
MAXIMUM TRANSMISSION PROTECTION
Synthetic Motorcycle Oils not only provide superior protection for motorcycle
engines, they also provide superior gear protection, meeting API GL-1 and SAE
80W/90 (MCF) and SAE 90 (MCV) gear lube requirements.
Viscosity is the
most important characteristic of a lubricant. Motorcycle gears create a shearing
effect that causes permanent oil viscosity loss. This thinning effect reduces
the oil’s ability to prevent metal-to-metal contact and wear. AMSOIL Synthetic
Motorcycle Oils exhibit absolute shear stability as measured by the industry
recognized Kurt Orbahn shear stability test (ASTM D-6278). They provide superior
protection compared to competitive oils and eliminate the need for separate
gearbox or chaincase oils.
high temperatures and tight tolerances common to motorcycle applications also
High Temperature/High Shear (HTHS) Test (ASTM D-4683) measures a lubricant’s
viscosity under severe high temperature and shear conditions. The more
resistant an oil is to high-temperature viscosity loss, the better it protects,
and even a HTHS difference of 0.1 cP makes a significant difference.
Synthetic Motorcycle Oils exhibit the highest HTHS viscosities of competing
synthetic and conventional motorcycle oils. They provide the best high
temperature viscosity protection, giving motorcycle owners peace-of-mind during
extensive idle times or when riding in hot weather conditions.
WET CLUTCH PERFORMANCE
motorcycles utilize a clutch that is immersed in the motor oil. The friction
modifiers present in many automotive motor oils and the extreme pressure
additives present in EP gear lubricants produce a low coefficient of friction
between the clutch discs and plates, resulting in clutch slippage and glazing.
Slippage leads to increased operating temperatures and reduced clutch life.
AMSOIL Synthetic Motorcycle Oils are formulated without friction modifiers,
providing positive clutch engagement, longer equipment life and reduced
temperatures. AMSOIL Synthetic Motorcycle Oils meet the clutch compatibility
requirements mandated by the JASO MA/MA2 standard.
motorcycles spend the majority of their lives either parked or in storage, but
most motorcycle oils fail
address corrosion problems. Corrosion protection during storage and in humid
conditions is essential to extending equipment life. AMSOIL Synthetic
Motorcycle Oils are formulated with specialized additive technology that not
only protects against corrosion and acids during operation, but also provides
exceptional protection during storage. The ASTM D-1748 Rust Test measures a
lubricant’s ability to protect against rust and corrosion. A standard metal
reference coupon is immersed in the test oil before being placed in a humidity
cabinet for 24 hours at 120 degrees F. The coupon treated with AMSOIL 20W-50
Synthetic Motorcycle Oil showed no signs of rust and corrosion, while the
competitor failed the test.
Motorcycles operate in demanding, high heat conditions that require robust
high-temperature deposit control additives. While many conventional oils break
down and oxidize when faced with high temperatures, causing formation of carbon
and sludge deposits, AMSOIL Synthetic Motorcycle Oils effectively withstand oil
breakdown and oxidation, keeping equipment running cooler and minimizing oil
consumption, thickening and emissions. Air-cooled engines get especially hot
while idling in traffic, commonly reaching temperatures of 270 degrees
Fahrenheit or higher. The extra margin of protection provided by AMSOIL
Synthetic Motorcycle Oils is especially important for hot-running air-cooled
