When it comes to farm motorcycles in New Zealand, no brand comes close to Yamaha. The AG series has been the backbone of Kiwi farming for decades, trusted by sheep and beef farmers, dairy operators, deer farmers, and lifestyle block owners from Northland to Southland. This guide breaks down the two models in the current Yamaha AG lineup and helps you choose the right bike for how you farm.
Why Yamaha Dominates the NZ Farm Bike Market
Yamaha's farm bikes aren't adapted road bikes or repurposed trail bikes, they're purpose-engineered from the ground up for agricultural work. That means long service intervals, bombproof reliability, low centre of gravity for hill country stability, and a riding position that's comfortable across a full working day. Parts are widely available, every Yamaha dealer can service them, and resale values are strong. It's why the AG series consistently outsells every other farm bike in New Zealand.
The Yamaha AG125 — New Zealand's Number One Farm Bike
The 2026 Yamaha AG125T is the best-selling farm motorcycle in New Zealand — full stop. It's the bike found on more Kiwi farms than any other, and it's been that way for years. Here's why.
What Makes It So Popular?
The AG125 hits the sweet spot of price, performance, and practicality that most NZ farming operations need. The 124cc air-cooled four-stroke engine is economical to run, straightforward to maintain, and delivers smooth, predictable power across the rev range. There's no complexity here — just a reliable, hardworking farm tool that starts every morning and keeps going all day.
Built for Farm Work
- Low seat height for easy mounting and dismounting across a long working day
- Upright riding position to maintain visibility over uneven terrain
- Robust steel frame engineered for the rigours of farm use, not just road riding
- Drum brakes front and rear — reliable performance in muddy conditions where disc brakes can pack with debris
- High ground clearance to handle rough paddock ground, ruts, and drain crossings
- Wide, grippy tyres for traction in wet grass and soft ground
Who Is the AG125 Best For?
The AG125 is the right choice for most NZ farming operations. If you're covering relatively flat to rolling country, doing typical daily stock work, and want the most cost-effective reliable farm bike on the market, this is your bike. It's also an excellent choice as a second farm bike, a bike for staff, or a first farm bike for younger riders graduating from a smaller machine.
The Yamaha AG200 — The Only Purpose-Built Farm Bike Still Made in Japan
The 2026 Yamaha AG200 occupies a unique position in the global motorcycle market: it is the only purpose-built farm motorcycle still manufactured in Japan. In an era where production has shifted offshore for most brands, Yamaha continues to build the AG200 in Japan to the same exacting standards that made it legendary. That alone tells you something about the importance Yamaha places on this machine.
More Displacement, More Capability
The AG200's 196cc air-cooled four-stroke engine delivers meaningfully more torque than the AG125, and on a farm, torque is everything. Climbing steep hill country, powering through heavy mud or carrying a full load of gear, the AG200 has the grunt to get it done without labouring. It pulls strongly from low revs and keeps pulling all the way through the range.
Built for Serious Country
The AG200 was designed with New Zealand and Australian hill country in mind. Its geometry, weight distribution, and suspension travel are optimised for steep, technical terrain where a lighter or less capable bike would struggle. Features include:
- Larger 196cc engine with more torque for hill work and heavy loads
- Stronger frame and suspension rated for demanding terrain
- Low gearing for maximum traction on steep slopes
- Drum brakes front and rear — proven, reliable, and mud-resistant
- High ground clearance and wide-section tyres for soft and rough ground
- Japanese manufacturing quality — tight tolerances, consistent build quality, long service life
Who Is the AG200 Best For?
If you're farming steep hill country, carrying heavy loads regularly, or working in challenging conditions where the extra torque and robustness make a genuine difference to your day, the AG200 is the better investment. Serious sheep and beef operations on rolling to steep terrain, deer farmers, and anyone who puts their farm bike through genuine hard work will appreciate what the bigger engine delivers. It costs more than the AG125, but it earns that difference in capability every day.

Maintenance Tips to Get the Most From Your Yamaha AG
- Service every 1500km or at least once a season, farm dust and mud accelerate contamination
- Check and adjust tyre pressures regularly, correct pressure dramatically improves economy, grip and tyre life
- Inspect and lubricate the drive chain after every wash-down or wet week
- Wash throughly and inspect at least once a week for any damage or wear, check the oil level
- Keep the air filter clean, dusty farm conditions clog filters faster than road riding
- Book an annual service with your Yamaha dealer before the busy farming season
