Full 360° "any-side-up"

Mini 4-Stroke Series

The innovative design of Honda’s Mini 4-Stroke engines allows them to be used and stored in any position for full 360° usability.

Upright, sideways, even upside down – the Mini 4-Strokes will still run great.

An exclusive Honda rotary-slinger 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. An oil return port positioned in the centre of the reservoir prevents oil from accidentally flowing into the combustion chamber.

Approximately 20% the operating cost of comparable 2-stroke engines

Mini 4-Stroke Series

Efficient 4-Stroke technology not only offers superior fuel economy, it also requires no mixing of oil in the engine’s fuel supply. This substantially reduces both oil consumption and the emission of unburned oil in the exhaust (up to 90% better than comparable similar horsepower class gasoline 2-stroke engine).

The results include better all-around environmental performance and operating costs that actually decrease the more the engine is used!

Belt-driven OHC design

Mini 4-Stroke Series

In addition to the milder operating noise of 4-Stroke engines in general, the Mini 4-Stroke’s belt-driven OHC design further reduces unpleasant mechanical noise. Its lighter piston and other moving parts help keep vibration to a comfortable level.
