Hyosung GV 125 Aquila (2000-2017): A Timeless Entry-Level Cruiser Review

Introduction

The Hyosung GV 125 Aquila occupies a unique niche in the motorcycle world. As a South Korean cruiser produced for nearly two decades, it’s built a reputation as an accessible entry point for riders drawn to the laid-back cruiser lifestyle but constrained by licensing restrictions or budget. With its V-twin engine, classic styling, and approachable ergonomics, the Aquila promises the feel of a larger bike in a compact package. But does it deliver? Let’s dive into what makes this motorcycle tick – and where it stumbles.

Design & Ergonomics: Small Bike, Big Presence

At first glance, the GV 125 Aquila punches above its weight class visually. The teardrop fuel tank, swept-back handlebars, and low-slung profile mimic the DNA of American cruisers twice its size. Over its production run, Hyosung offered color schemes ranging from understated black to vibrant red/black combinations, with later models (post-2011) adopting more contemporary two-tone finishes. The 2016 update introduced sharper tank badges and a redesigned headlight casing, giving it a slightly more modern edge.

The riding position is where this bike truly shines. With a seat height ranging between 665-710mm (26.2-28 inches) depending on model year, even shorter riders can plant both feet firmly. The forward-set pegs and neutral handlebar position create a relaxed posture – you sit in this bike rather than on it. However, the bench-style seat, while wide enough for short commutes, lacks contouring for longer rides. After an hour in the saddle, you’ll be craving an aftermarket gel insert (which MOTOPARTS.store conveniently stocks).

Engine Performance: Character Over Speed

Let’s address the elephant in the room first: the 124-125cc V-twin. Producing between 14-14.8 HP (10.4-11 kW) and peaking at 9.2-12.5 Nm of torque, this isn’t a bike for highway dominance. However, dismissing it based on specs alone would be a mistake. The 60° V-twin configuration gives the Aquila something many small-displacement cruisers lack – personality.

From idle, the engine emits a throaty burble that’s surprisingly assertive for a 125cc. Credit goes to the DOHC 4-valve heads and 180° crankshaft, which provide a distinct exhaust pulse. Throttle response via the Mikuni carburetor (or fuel injection on 2016+ models) is crisp, though the power band lives high in the rev range. You’ll need to work the 5- or 6-speed gearbox (depending on model year) to keep momentum on hills, but the light clutch pull makes this less of a chore than expected.

Real-World Riding Experience
- City Commuting: An absolute joy. The narrow 800-875mm (31.5-34.4-inch) width slips through traffic, while the 14L (3.7 US gal) tank provides 250-300 km (155-186 mi) range.
- Highway Limitations: Top speed hovers around 100-110 km/h (62-68 mph), but sustained runs above 90 km/h (56 mph) feel strained. Vibration through the pegs becomes noticeable at 8,000 RPM.
- Two-Up Riding: Possible, but the 346-388 kg (763-855 lb) curb weight and modest torque mean you’ll want to stick to flat urban areas.

Handling & Suspension: Predictable, If Not Exciting

Hyosung prioritized stability over agility in the Aquila’s chassis design. The steel double-cradle frame and 1490-1515mm (58.7-59.6-inch) wheelbase give it planted manners at the expense of quick direction changes. Entry-level riders will appreciate this predictability, though seasoned motorcyclists might find it overly sedate.

Suspension Breakdown
- Front: Telescopic forks with 170mm (6.7 inches) of travel handle bumps adequately, albeit with occasional harshness over sharp imperfections.
- Rear: Twin shock absorbers (pre-2010) evolved to hydraulic units in later models. Preload adjustment is limited, so heavier riders should consider upgrades.

Braking performance reflects its era. The single 260mm front disc (2-piston caliper post-2016) provides decent stopping power, but the rear drum brake (130mm on earlier models) demands assertive lever pressure. Swapping to sintered pads and a braided stainless line (available at MOTOPARTS.store) dramatically improves feel.

Competition: How Does the Aquila Stack Up?

In the 125cc cruiser segment, the Aquila faces three main rivals:

1. Honda Shadow 125
2. Pros: Honda’s legendary reliability, smoother single-cylinder engine
3. Cons: Less charismatic engine note, higher price point

4. Verbal: The Shadow feels more refined but lacks the Aquila’s V-twin charm.

5. Yamaha Virago 125

6. Pros: Lighter weight (128 kg/282 lb), lower seat height
7. Cons: Air-cooled SOHC engine feels agricultural compared to Hyosung’s DOHC

8. Verbal: Better for pure beginners, but less satisfying for developing riders.

9. Suzuki Marauder 125

10. Pros: Liquid cooling allows sustained highway speeds
11. Cons: Bland styling, heavier than Hyosung
12. Verbal: A technical match, but the Aquila wins on curb appeal.

Hyosung’s Edge: The Aquila’s V-twin configuration and cruiser aesthetics give it an outsized presence. While Japanese competitors may edge it in reliability surveys, the Hyosung offers more emotional engagement – a crucial factor in the style-conscious cruiser market.

Maintenance: Keeping Your Aquila Rolling

The GV 125’s mechanical simplicity works in its favor for home maintenance. Key considerations:

1. Valve Adjustments
2. Intake: 0.10-0.20mm (0.004-0.008 in)
3. Exhaust: 0.20-0.30mm (0.008-0.012 in)

4. Service interval: Every 6,000 km (3,728 mi)

5. Oil Changes

6. 1.5L (1.6 qt) of SAE 10W-40

7. Use JASO MA2-certified oil for wet clutch compatibility

8. Carburetor Tuning

9. Factory setting: 2 turns out on air screw

10. Consider upgrading to a Stage 1 jet kit for improved midrange

11. Chain Care

12. 138-link 520 chain
13. Maintain slack at 25-35mm (1-1.4 in)

14. Clean/lube every 500 km (311 mi)

15. Winter Storage

16. Add fuel stabilizer to prevent carb varnishing
17. Disconnect battery or use tender

Conclusion: Who Should Buy a GV 125 Aquila?

The Hyosung GV 125 Aquila isn’t about raw performance – it’s about accessibility. For new riders seeking cruiser styling without the bulk of a 650cc+ machine, or urban commuters wanting an economical runabout with character, this bike delivers. While its components won’t wow gearheads, the robust aftermarket support (including our curated selection at MOTOPARTS.store) allows owners to personalize and upgrade as their skills progress.

Is it perfect? No. The mirrors vibrate at high RPMs, the stock exhaust note could be richer, and the switchgear feels dated. But these are forgivable sins in a bike that costs pennies to run and puts a smile on your face every time you twist the throttle. Seventeen years of continuous production don’t lie – the Aquila has earned its place as a gateway to the cruiser life.
