Honda eGX Technical Specifications

The Honda eGX is an advanced, electrified power unit that accommodates the needs of the construction machinery market, operating with zero-emissions and enabling equipment to be more compatible for indoor work environments and for outdoor work sites near residential areas where low noise is an important factor.

The high-performance, battery-powered motor, designed to closely match the performance output of conventional Honda GX100 and GXR120 industrial engines, provides efficient, convenient and eco-conscious operation for existing or new applications in the 100 to 120 cc displacement category such as concrete trowels, vibratory plate compactors and rammers. The Honda eGX is powered by high-quality, rechargeable, lithium-ion batteries that are assembled in series and in parallel, delivering optimal performance and long life.

*The power rating of the Honda eGX measures the net power and net torque at 3600 rpm, as tested on a preproduction motor. Mass production motors may vary from this value. Actual power output for the motor installed in the final machine will vary depending on numerous factors, including the operating speed of the motor in the application, battery conditions, environmental conditions, maintenance, and other variables. Specifications subject to change without notice.
