01AUTOMOTIVE PARTS
Quiet precision for hand-held power tools
The King Tech GX25 is a compact 4-stroke petrol engine engineered for the rigours of hand-held garden equipment. Its red casing houses a sophisticated internal layout that prioritises smoothness and control over brute force.
Designed for tillers, brushcutters and pumps, this unit delivers consistent torque with minimal vibration. It suits operators who value fatigue-free handling and reliable performance across varied working angles.


02DESIGN
Compact architecture for maximum mobility
The engine employs a compact oil-immersed timing belt OHC configuration, integrating the valve train into the oil reservoir to save weight and volume. This structural choice supports the 360° inclinable capability, allowing the unit to be stored or operated in any orientation without compromising lubrication flow.

04DETAILS
Precise specifications and robust construction
With a bore and stroke of 35 x 26 mm and a compression ratio of 8.0:1, the single-cylinder unit produces 1.0 Nm of max net torque at 5000 rpm. A full-cover construction reduces snagging on branches, and the recoil starter provides reliable ignition via a transistorised system within the 26 x 26 x 23 cm carton.
05AT A GLANCE
The key points
- 25.0 cm³ displacement with 0.7 kW net power at 7000 rpm
- Oil-immersed timing belt reduces mechanical noise significantly
- 360° inclinable design allows operation in any position
- Recoil starter and transistorised ignition system included

About this product
Lighter pistons and other parts create less vibration, resulting in less fatigue during hand-held operation
Full-cover construction reduces snagging on branches or other objects during operation
The new Kingtech GX25 25cc displacement, 360°- inclinable 4-stroke engine is an ideal power source for a variety of hand-held power equipment.
The GX25 was developed to meet three design objectives: less weight; to be 360°- inclinable; and to provide outstanding environmental performance.
The engine employs the most compact oil-immersed timing belt OHC configuration, making it possible to incorporate the valve train into the oil reservoir for substantial weight and volume savings. Its rotary slinger pumping lubrication system ensures full oil lubrication no matter what the engine angle, allowing it to be continuously operated or stored in any position.
It also delivers an outstanding balance of all-round performance, combined with low noise and low vibration, for efficient, carefree operation.
