Mini 4-Stroke Engines
GENuINE
T
here are many reasons to insist on genuine Honda Engines. As the world’s largest
engine manufacturer, Honda offers more engine experience than anyone.
Experience born on racetracks and roadways around the globe. Experience that
keeps us on the cutting edge of engine performance technology and crosses our entire
product line. From automobiles, race cars, motorcycles and all-terrain vehicles to marine
engines, power equipment products and general-purpose engines, Honda is committed to
designing products that meet or exceed the demands of our customers across the board.
Based on the wide variety of products offered with our Honda Engines, we’re experts
at matching the right engine for the right job and producing engines that will
“get the job done.”
Throughout our history, Honda has been
dedicated to technological and environmental
innovation, and today is no different.
After all, we have a legendary reputation
to live up to. A reputation for unsurpassed

A reputation worth considering the next
time you’re in the market for an engine.
Net Power
The SAE J1349 standard measures net horsepower with the manufacturer’s production muffler and air cleaner in place.
Net horsepower more closely correlates with the power the operator will experience when using a Honda Engine powered
product. The power rating of the engines indicated in this document is the net power output tested on a production engine
for the model noted and measured at the rpm specified. Mass production engines may vary from this value. Actual power
output for the engine installed in the final machine will vary depending on numerous factors, including the operation speed
of the engine in application, environmental conditions, maintenance and other variables.

lubrication system keeps oil in a completely misted
state and circulates it using pressure fluctuations
generated by the movement of the piston. Built-in
passages effectively return the circulated oil to the
oil reservoir from every part of the engine, and an
oil return port positioned in the center of the reservoir
prevents oil from accidentally flowing into the
combustion chamber.

Low Noise & Vibration
In addition to the milder operating noise of 4-Stroke
engines in general, the Super Mini 4-Stroke’s belt-driven
OHC design further reduces unpleasant mechanical
noise, while its lighter piston and other moving parts
help keep vibration to a comfortable minimum.
Clean burning Performance
Honda’s environmentally conscious technology
results in significantly lower HC and NOx emissions
compared to 2-stroke engines.
Reduced Fuel & Oil Consumption
Efficient 4-Stroke technology not only offers superior
fuel economy, it also requires no mixing of oil in the
engine’s fuel supply, thus substantially reducing both
oil consumption and the emission of unburned oil in
the exhaust. The results include better all-around
environmental performance and operating costs that
actually decrease the more the engine is used!
