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

Commonly used to power pressure washers, generators, construction, industrial, horticultural equipment and small vehicles.


The fuel economy of the GX690 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. A hemispherical combustion chamber delivers rapid combustion.

Add a two barrel inner-vent carburetor 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.


The GX690's high capacity pump facilitates consistent oil delivery, and a handy oil alert so there is no risk of running dry and doing damage to the engine. There's a dual cylindrical air filter, and a large diameter air intake on board for superior cooling, perfect when operating over long periods of time.

The result is a long-lasting, high-performing and reliable engine.

FEATURES - Get the smoothest performance via an integrated cylinder and head as well as racing inspired forged steel connecting rods. The V-Twin range is exceptionally quiet thanks to a high capacity 36 blade cooling fan. Featuring aluminium push rods with steel clips, enjoy lighter weight, less vibration and quiet operation. The range is easy to use and maintain with conveniently located controls, with several configurations available, based on user preference. Better yet, it has an automotive-type spin-on oil filter. When there’s no time to waste, you’ll enjoy easy starting thanks
