The Goes G725 iS ATV (2014-2016): A Workhorse Built for Adventure
Introduction
The Goes G725 iS ATV, produced between 2014 and 2016, is a machine that straddles the line between utilitarian work companion and off-road adventurer. Designed for riders who demand reliability in harsh conditions, this quad bike combines rugged engineering with surprisingly refined features for its class. Over a multi-day test ride through muddy trails, rocky inclines, and open fields, the G725 iS proved itself as a versatile partner – but not without a few quirks that potential owners should consider. Let’s dive into what makes this ATV stand out in a crowded market.
Design & Build Quality
The G725 iS cuts an imposing figure with its 2040 mm (80.3 inches) length and 1200 mm (47.2 inches) width. The angular bodywork – available in bold yellow, stealthy black, or crisp white – looks industrial rather than flashy, signaling its work-first mentality. Aluminum rims (25-inch tires front and rear) sit within flared fenders that do an admirable job containing mud spray, though you’ll still want fender extensions for serious mucking.
At 336 kg (740.8 lbs) dry weight, this isn’t a machine you’ll manhandle out of ditches alone. The heft becomes an asset, however, when plowing through deep ruts or hauling heavy loads. The 300 mm (11.8 inches) ground clearance lets you straddle fallen logs with confidence, while the 1260 mm (49.6-inch) wheelbase provides stability on side slopes.
The cockpit area shows thoughtful touches: handlebar switches are glove-friendly, the digital dash remains readable in direct sunlight, and the 21L (5.55 US gal) fuel tank is strategically placed for a lower center of gravity. The rear rack’s 75 kg (165 lbs) capacity outperforms many competitors, though we’d recommend reinforcing the mounting points if regularly maxing it out.
Engine & Performance
Beating at the heart of the G725 iS is a 686cc liquid-cooled single-cylinder engine. The 102mm x 84mm (4.0” x 3.3”) bore and stroke ratio prioritizes low-end torque over top-end scream – exactly what you want when crawling up a rocky incline with a trailer in tow. Fuel injection ensures crisp throttle response even at altitude, a notable advantage over carbureted rivals.
Power delivery through the automatic CVT transmission is smooth but deliberate. There’s none of the rubber-band effect found in cheaper belt-driven systems, thanks to the robust shaft drive (cardan) final drive. Engaging 4x4 mode via the handlebar switch transforms the riding experience – front wheels bite into loose terrain with authority, while the front differential lock (a rare feature in this class) makes escaping axle-deep mud pits almost routine.
Top speed is governed at about 100 km/h (62 mph), though the G725 iS feels most natural cruising at 50-70 km/h (31-43 mph). The engine note is a muted thrum rather than an irritating buzz, making long rides less fatiguing. We averaged 14.5 L/100km (16.2 mpg) during mixed use – respectable for a 4x4 automatic in this weight class.
Handling & Suspension
The double A-arm front suspension (adjustable preload) and independent rear setup soak up washboard trails better than any solid-axle competitor. Dialing up the preload transforms the ride from plush to sporty – a boon when switching between trail riding and heavy hauling.
Steering requires muscle at low speeds – the 4x4 system’s inherent resistance combines with the 25/8-12 front tires’ aggressive tread. Once moving above 15 km/h (9 mph), the power steering effect of the CVT eases effort significantly. Braking is confident with dual hydraulic discs, though the rear tends to lock first during panic stops on gravel.
Where the G725 iS truly shines is technical terrain. The combination of 25-inch tires (25/8-12 front, 25/10-12 rear), locked 4x4 mode, and precise throttle modulation lets you crawl over obstacles that would stop lesser quads. We navigated a 35-degree rock face (dry conditions) without wheel spin – a testament to both the drivetrain and weight distribution.
Competition
Polaris Sportsman 700
The Sportsman’s lighter weight (386 lbs vs 740 lbs) makes it nimbler in tight woods, but it lacks the G725’s shaft drive durability. Frequent belt changes vs zero driveshaft maintenance? For heavy users, the Goes wins.
Can-Am Outlander 650
Can-Am’s TTI rear suspension outclasses the G725’s setup in comfort, and the Rotax engine offers more top-end power. However, the Outlander’s higher price and complex electronics deter budget-conscious buyers.
Yamaha Grizzly 700
Yamaha’s Ultramatic transmission is smoother, and the Grizzly feels more “premium.” Yet the G725 counters with superior ground clearance (+50mm) and a sturdier rear rack system.
Verdict: The G725 iS carves its niche among riders prioritizing mechanical simplicity and brute capability over refinement. It’s the ATV equivalent of a diesel pickup – not glamorous, but built to outlast the payment plan.
Maintenance
The G725 iS rewards diligent owners. Key considerations:
-
Shaft Drive Care: Unlike belt-driven rivals, the cardan system needs only annual gear oil changes. Use JASO MA2-compliant 75W-90 oil (available at MOTOPARTS.store) to prevent premature wear.
-
Cooling System: Flush coolant every 2 years or 200 hours. The liquid-cooled design avoids air-cooled engines’ overheating issues but demands clean fluid.
-
Suspension Pivots: Grease zerks every 50 hours – critical given the independent rear’s complexity. Our store carries needle adapters for hard-to-reach fittings.
-
ECU Sensitivity: The fuel injection system dislikes stale gas. Add fuel stabilizer if storing >1 month. Keep the air filter clean – a clogged filter triggers limp mode faster than on carbureted models.
Upgrade Recommendations:
- High-output stator for winch/light add-ons
- Skid plates (factory protection is minimal)
- Our premium brake pads reduce dust and fade
Conclusion
The Goes G725 iS isn’t about thrills – it’s about capability you can trust. While newer ATVs offer flashier tech, this generation’s mechanical simplicity makes it a favorite among ranchers, hunters, and riders who value function over finesse. The lack of recurring belt costs alone justifies consideration for high-mileage users.
Would we choose it for weekend trail rides? Maybe not – the weight and steering effort penalize casual use. But for anyone needing a diesel-like ATV that’ll start in -20°C, ford creeks without complaint, and haul game out of the backcountry? The G725 iS remains a compelling choice, especially when paired with MOTOPARTS.store’s durability-focused upgrades.
