Yamaha AG125 Farm Bike

The Yamaha AG125 is built for New Zealand farms, combining the legendary reliability of the original AG series with modern features that make every day’s work easier. Whether you’re checking stock, shifting fences or travelling across rugged terrain, the AG125 is designed to handle demanding farm conditions with confidence.

Powered by a dependable 124cc air-cooled four-stroke engine, the AG125 delivers smooth, controllable power with excellent traction, even in muddy paddocks and challenging terrain. Its electric start provides reliable starting in all conditions, while the monoshock rear suspension offers improved comfort and handling across rough tracks.

Built with the features farmers rely on, the AG125 includes sealed drum brakes, a fully enclosed chain case and extensive protection for the engine, chain and handlebars to minimise maintenance and maximise durability. Heavy-duty front and rear cargo racks make it easy to carry tools, fencing gear and everyday farm essentials.
