Honda's V-Twin range of engines are the cream of the crop, powering pressure washers, water pumps and commercial lawncare equipment.

The GX630 V-Twin can also be found in cultivators, agricultural equipment and generators as well as heavy-duty forestry and industrial industries.


The fuel economy of the GX630 V-Twin is similar to fuel injection, with the simplicity of carburetion ensuring that running this unit is easy on both your pocket and the environment.

It features a digital CDI ignition system with variable timing, as well as a forged steel crankshaft and insert style rod bearings for efficient operation. There's also a rev limiter to protect against damage from over-revving.

Add a two barrel inner-vent carburettor for more precise fuel metering and a 9.3:1 compression ratio, and you'll be generating high power output without the need for premium fuel.
