SYM MaxSYM 400 (2010–2020) Review: A Touring Scooter Built for Comfort and Reliability

Introduction

The SYM MaxSYM 400 is a maxi-scooter that carved its niche as a practical yet spirited machine for riders who prioritize comfort, storage, and fuss-free commuting. Produced from 2010 to 2020, this Taiwanese workhorse blends touring capability with urban agility. After spending time with a well-maintained 2019 model, here’s why this scooter deserves a closer look—whether you’re navigating city traffic or planning weekend getaways.

Design & Ergonomics: Form Meets Functionality

The MaxSYM 400’s design leans into the classic maxi-scooter ethos: a muscular front end with dual LED headlights (later models), a tall windscreen, and a stepped seat that accommodates rider and passenger. The bodywork is unapologetically bulky, but it’s purposeful—those curves hide 14.7 liters (3.88 US gallons) of fuel and under-seat storage large enough to swallow a full-face helmet.

The cockpit feels car-like, with a wide handlebar and a mix of analog dials (speedometer, tachometer) and a digital display (fuel gauge, trip meters). SYM offered muted color options like champagne brown and matte black, which age better than flashier alternatives. The 750 mm (29.5-inch) seat height is accessible for riders of average height, though the scooter’s 229 kg (505 lbs) dry weight demands respect when maneuvering at parking speeds.

Engine & Performance: Smooth Operator

At its heart lies a 399 cc liquid-cooled single-cylinder engine with a ceramic-coated cylinder for durability. Output figures hover around 35 HP (25.5 kW) and 34.5–36.2 Nm (25.4–26.7 ft-lbs) of torque, delivered via a seamless CVT transmission. Throttle response is linear rather than thrilling, with peak power arriving at 7,000 RPM.

In real-world testing, the MaxSYM accelerates briskly from 0–60 km/h (0–37 mph), ideal for urban sprints. The CVT keeps vibrations minimal, though the engine note becomes buzzy near its 143–145 km/h (88–90 mph) top speed. Fuel efficiency is a strong suit: 4.0 L/100 km (58.8 mpg) means over 350 km (217 miles) from a full tank—perfect for long rides.

Handling & Ride Quality: Stability Over Sportiness

The MaxSYM’s 1,570 mm (61.8-inch) wheelbase and 15-inch front/14-inch rear wheels lend it planted stability at highway speeds. The suspension setup—41 mm telescopic forks upfront and a 5-way preload-adjustable rear monoshock—is tuned for comfort, absorbing potholes without drama.

However, the scooter’s weight is felt in tight corners. Lean angles are limited by the floorboards, which scrape earlier than a motorcycle’s pegs. Braking is confident, especially on ABS-equipped models, with dual 275 mm front discs and a single rear disc providing ample stopping power. The 120/70-15 front and 160/60-14 rear tires strike a balance between grip and longevity.

Features & Practicality

SYM packed the MaxSYM with thoughtful touches:
- Integrated storage: A deep glovebox, USB charging port (later models), and cavernous under-seat compartment.
- Adjustable windscreen: Reduces fatigue on highways, though taller riders might still crave more coverage.
- Belt final drive: Low-maintenance compared to chain-driven rivals.

The analog-digital dash lacks modern connectivity but is legible in direct sunlight. Optional ABS (post-2014) adds safety, though base models rely on combined braking.

Competition: How Does It Stack Up?

The MaxSYM 400 faced stiff rivals in the 400cc scooter segment:

1. Yamaha XMAX 400: Lighter, sharper, and more tech-forward, but pricier. The XMAX feels sportier but sacrifices some of the SYM’s storage space.
2. Suzuki Burgman 400: A direct competitor with similar specs. The Burgman’s CVT is smoother, but the SYM counters with better fuel efficiency.
3. Honda Forza 350: Smaller engine but agile. The Forza wins in city maneuverability, while the MaxSYM dominates long-distance comfort.

The SYM’s edge lies in value-for-money—it undercuts Japanese rivals while offering comparable touring potential. Build quality is robust, though fit-and-finish details (e.g., switchgear) feel utilitarian next to a Honda.

Maintenance: Keeping Your MaxSYM Healthy

The MaxSYM 400 is straightforward to maintain, but attention to these areas will extend its lifespan:

1. Oil Changes: Use 1.9L of 10W-40 API SJ oil (with filter). SYM recommends changes every 5,000 km (3,100 miles).
2. Cooling System: Flush with 1.1L of coolant every 2 years. Check for leaks around the electroplated ceramic cylinder.
3. Belt & Rollers: Inspect the CVT belt every 12,000 km (7,500 miles). Worn rollers cause sluggish acceleration.
4. Brakes: Replace pads when thickness drops below 3 mm. Use DOT 4 fluid and bleed annually.
5. Tires: Maintain 2.0 bar (29 psi) front and 2.25–2.5 bar (32–36 psi) rear pressures for optimal wear.

Common wear items available at MOTOPARTS.store:
- NGK CR8E spark plugs (0.7 mm gap).
- OEM-spec brake pads.
- High-performance air filters for EFI models.

Verdict: Who Should Buy It?

The SYM MaxSYM 400 isn’t a headline-grabber, but it’s a steadfast companion for riders seeking:
- Tour-ready comfort: That plush seat and wind protection eat miles effortlessly.
- Low-maintenance ownership: Belt drive and proven engine simplify upkeep.
- Everyday practicality: Storage, fuel range, and ease of riding.

It’s less suited for thrill-seekers or those craving cutting-edge tech. But as a dependable, all-rounder scooter, the MaxSYM 400 remains a compelling choice—especially when paired with MOTOPARTS.store’s catalog of upgrades and OEM replacements.
