The world's lightest OHC engine, the Honda Mini 4-stroke engine requires no fuel/oil mixing, and runs at approximately half the operating cost of comparable 2-stroke engines. A full 360° "any-side-up" operation means you can use and store the UMC425 in any position, and take advantage of the exclusive rotary-slinger lubrication system. The carburetor is equipped with an accelerator pump for fast, easy acceleration, and an efficient port configuration and large diameter valves maximise power output. Fuel Efficient, High Output Operation. Lighter, more rigid valve train.
