SYM MAXSYM 400 (2021-2022) Review: A Maxi-Scooter Built for the Modern Rider

Introduction

The SYM MAXSYM 400 represents a compelling blend of practicality and performance in the maxi-scooter segment. Produced between 2021 and 2022, this Taiwanese-built machine aims to strike a balance between urban agility and touring capability. With its Euro 5-compliant engine, generous storage options, and tech-forward features, it’s designed for riders who want to conquer both city commutes and weekend adventures. After spending time with this scooter, here’s how it stacks up in the real world.

Design: Function Meets Subtle Style

The MAXSYM 400 doesn’t scream for attention, but its design language is purposeful. The sharp LED headlight and clean body lines give it a modern, almost futuristic look, while the color options—matte grey, matte blue, white, and standard grey—cater to both understated and bold tastes. At 2,230 mm (87.8 inches) long and 215 kg (474 lbs), it’s a substantial machine, yet the 800 mm (31.5-inch) seat height keeps it accessible for riders of average height.

The chassis uses a steel underbone frame, which contributes to its rigid feel. Storage is a highlight: the underseat compartment fits a full-face helmet, and the dual front glove boxes (one locking) add convenience. The adjustable windscreen is a thoughtful touch, though taller riders might wish for more height adjustment.

Engine and Performance: Smooth Operator

Powering the MAXSYM 400 is a 399 cc liquid-cooled single-cylinder engine producing 33.5 HP (24.5 kW) and 39.5 Nm (29.1 ft-lbs) of torque. The CVT transmission delivers seamless acceleration, with peak torque arriving at 5,250 RPM—perfect for zipping through traffic.

On the open road, the scooter reaches a top speed of 139 km/h (86.4 mph), though it feels most comfortable cruising at 100–110 km/h (62–68 mph). The engine’s refinement stands out; vibrations are minimal, and the exhaust note is muted. Fuel injection ensures crisp throttle response, and the claimed fuel economy hovers around 27–30 km/l (63–70 mpg), thanks to its 13-liter (3.43-gallon) tank.

Comfort and Ergonomics: All-Day Riding

SYM nailed the ergonomics here. The floorboards offer ample legroom, and the wide seat provides excellent support for both rider and passenger. The suspension setup—a telescopic fork upfront and a 5-way preload-adjustable rear swingarm—absorbs bumps competently, though sharper potholes can feel jarring.

At highway speeds, the windscreen does a decent job deflecting wind, but buffeting becomes noticeable above 110 km/h (68 mph). The 160/60-14 rear tire and 120/70-15 front tire strike a good balance between grip and stability, and the ABS-equipped dual front discs (275 mm) inspire confidence during hard braking.

Technology and Features: Smarter Than Average

The MAXSYM 400’s hybrid digital-analog dashboard is intuitive, displaying speed, fuel level, and trip data clearly. LED lighting across the board ensures visibility, and the inclusion of a USB charging port in the glovebox is a welcome modern touch.

The Euro 5 compliance future-proofs this scooter, and the belt final drive requires minimal maintenance compared to chain-driven rivals. SYM’s focus on practicality shines through details like the remote seat opener and built-in helmet hook.

Competition: How It Stacks Up

The maxi-scooter segment is fiercely competitive. Here’s how the MAXSYM 400 holds its ground:

• Yamaha XMAX 300: Lighter and nimbler, but the MAXSYM’s larger engine and storage capacity give it an edge for touring.
• Honda Forza 350: Offers similar tech but sacrifices underseat space. The MAXSYM’s torque advantage is noticeable on inclines.
• BMW C 400 X: More premium finishes and tech features, but at a significantly higher price point.

The SYM’s value proposition lies in its combination of power, storage, and affordability in maintenance costs.

Maintenance: Keeping It Road-Ready

Owners of the MAXSYM 400 will appreciate its straightforward maintenance needs:

• Engine Oil: Use SAE 10W-40 (1.8L without filter, 1.9L with filter). Replace every 5,000 km (3,100 miles).
• Coolant: 1.7L of ethylene glycol-based fluid. Check levels biannually.
• Belt Drive: Inspect every 12,000 km (7,500 miles) for wear.
• Tire Pressure: 2.3 bar (33 psi) front / 2.5 bar (36 psi) rear for optimal grip and longevity.
• Spark Plug: NGK CPR8EA-9 with a 0.8–0.9 mm electrode gap. Replace every 10,000 km (6,200 miles).
