Fuel Efficiency Operation

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.

Proven Reliability

The GX630's high capacity pump facilitates consistent oil delivery, and a handy oil alert will help protect your motor from running dry.

There's a dual cylindrical air filter, and a large diameter air intake on board for superior cooling.

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