SYM Joymax GTS 125 (2011-2020) Review: The Underrated Maxi-Scooter for Practical Riders

Introduction

The SYM Joymax GTS 125 occupies a unique space in the maxi-scooter segment - a practical workhorse that prioritizes functionality over flashiness. Produced from 2011 through 2020, this Taiwanese-built machine quietly built a reputation as a dependable urban companion, particularly in European and Asian markets. While it never achieved the cult status of its Japanese rivals, the Joymax GTS 125 offers a compelling package that deserves closer inspection. After spending a week with a well-maintained 2017 model, here's why this scooter might surprise you.

Design & Ergonomics

At first glance, the Joymax GTS 125 presents a conservative but proportional design. The 2,160mm (85-inch) length and 760mm (29.9-inch) width create a substantial presence without feeling bulky. SYM's designers opted for clean lines over aggressive styling, resulting in a look that's aged better than many angular contemporaries. The twin-headlight front fascia gives it proper "maxi-scooter" credentials, while the color-matched body panels (available in blue, black, silver, and occasionally purple) maintain a cohesive appearance.

The stepped seat sits at a accessible 780mm height, accommodating riders from 160cm (5'3") to 185cm (6'1") comfortably. What impressed most was the floorboard design - SYM managed to create generous legroom while maintaining a narrow profile at the knees, making filtering through traffic surprisingly easy. The 1475mm (58.1-inch) wheelbase contributes to stable tracking without sacrificing agility.

Practical touches abound:
- 12V 55W halogen headlights (adequate but worth upgrading for night riders)
- Clear analog-digital instrument cluster with fuel gauge and clock
- Lockable under-seat storage (fits a full-face helmet plus small items)
- Integrated rear rack ready for top case installation

The 2016+ models received subtle upgrades including revised bodywork seams for better weather protection and a slightly taller windscreen. While build quality can't match premium European brands, panel gaps are consistent and switchgear operates with positive feedback.

Engine & Performance

At its heart lies a 124.5cc single-cylinder four-stroke engine that evolved during its production run. Early models (pre-2015) used a carbureted setup meeting Euro 2/3 standards, while later versions adopted electronic fuel injection (EFI) for improved cold starts and emissions compliance. Our test bike's EFI system delivered smooth throttle response with none of the low-RPM hesitation that plagues some small-displacement FI engines.

Key specs:
- Power: ~11 HP @ 7,500 RPM (estimated)
- Torque: ~10 Nm @ 6,000 RPM
- Top speed: 105 km/h (65 mph) indicated
- Fuel consumption: 35-40 km/l (82-94 mpg)

The liquid-cooled design (still rare in 125cc scooters) ensures consistent performance during extended rides. While acceleration won't thrill adrenaline seekers, the CVT transmission provides seamless progress up to 80 km/h (50 mph). Steep hills require planning, but the engine never feels strained - a testament to SYM's electroplated ceramic cylinder technology that reduces friction and wear.

Highway capability exists in moderation. At 90 km/h (56 mph), the engine spins at about 80% capacity, leaving minimal overtaking reserves. However, the chassis remains composed at these speeds, aided by the 168kg (370lb) wet weight that enhances stability without feeling cumbersome at low speeds.

Ride & Handling

SYM's chassis engineers struck a commendable balance between comfort and responsiveness. The telescopic front forks and rear swingarm suspension (with 5-way preload adjustment on later models) soak up urban imperfections better than many rivals. Only severe potholes upset the composure, transmitting sharp impacts through the steel frame.

The 14-inch front/13-inch rear wheel combination (on 2017+ models) enhances straight-line stability compared to smaller-wheeled scooters. Lean angles proved generous for a maxi-scooter, though the center stand occasionally ground earlier than expected during spirited cornering.

Braking performance from the 220mm single discs (both ends) inspires confidence. The rear lever requires a firm pull, but combined braking action prevents nose-diving during panic stops. Upgrading to sintered pads would benefit aggressive riders.

Comfort & Practicality

Long-distance comfort exceeds expectations for a 125cc machine. The wide seat maintains cushioning integrity even after 2-hour stints, while the ergonomic triangle (bars-seat-floorboards) suits both casual and committed riding postures. Wind protection from the mid-height screen proves adequate up to 70 km/h (43 mph), with buffeting only becoming noticeable near top speed.

The 12-liter (3.17-gallon) fuel tank enables 350-400km (217-248mi) ranges between fill-ups - a boon for commuters. Storage solutions impress:
- 25L under-seat compartment (fits full-face helmet)
- Deep front glovebox with 12V outlet
- Optional rear rack compatible with 45L top cases
