Why choose this engine?

The Honda GXH50 QXB4 engine is an ideal replacement engine for the Belle Mini Mix 150 cement mixer.

With an OHV design, it has increased efficiency and optimal power transfer. Not only that, but it has a precision camshaft design and high compression ratio for better fuel efficiency.

The precision engineered components result in lower vibration resulting in a much smoother performance. The ball bearing supported crankshaft also provides a smoother performance by adding even greater stability.

The GXH50 QXB4 is exceptionally quiet thanks to the large capacity multi-chamber exhaust system, sophisticated air intake system, forged steel crankshaft and rigid crankcase, and the noise reducing materials used.

Engine damage is avoided thanks to the oil alert, which automatically shuts the unit down if the oil drops below a safe operating level. 

This engine has incredibly easy starting with an automatic decompression system and a heavy duty recoil starter, making each start simple and reliable.


Honda customers deserve complete peace of mind when purchasing the GXH50 QXB4, which is why it comes with a 12 months warranty.
