Kymco AK 550 (2017–2021) Review: The Maxi-Scooter That Redefines Touring Thrills

Introduction

The Kymco AK 550 isn’t just a scooter—it’s a declaration of intent. From the moment you swing a leg over its low-slung seat, the AK 550 challenges every preconception about what a maxi-scooter can be. Produced between 2017 and 2021, this Taiwanese marvel blends sportbike DNA with scooter practicality, creating a machine that’s as at home carving mountain passes as it is commuting through urban sprawl. Having spent time with this two-wheeled Swiss Army knife, I’m here to break down why it remains a compelling choice for riders who refuse to compromise.

Design: Where Aggression Meets Elegance

The AK 550’s design language shouts “sport tourer” from every angle. The twin LED headlights—arranged like a predator’s narrowed eyes—give it a road presence that humbles smaller bikes. Kymco’s Anniversary Edition badging (the “AK” stands for Anniversary Kymco) adds subtle prestige, while the sculpted bodywork flows back to a split-style seat that looks lifted from a premium naked bike.

Available in muted tones like Phantom Black and Titanium Gray (with occasional bold options like Deep Red), the color schemes emphasize its premium aspirations. The 785mm (30.9") seat height is a masterstroke—it’s accessible for shorter riders yet doesn’t force taller pilots into a knees-up position. Storage? The underseat compartment swallows a full-face helmet, and the front glove boxes handle smaller essentials.

But it’s the details that impress: the inverted forks’ gold accents, the embossed seat stitching, and the way the 15-inch alloy wheels fill out the 120/70 front and 160/60 rear tires. This isn’t just transportation; it’s a statement.

Engine & Performance: Twin-Cylinder Thunder

At the heart beats a 550.4cc liquid-cooled parallel twin—a rarity in scooters. The numbers speak volumes: 53 HP at 7,500 RPM and 55.6 Nm (41 lb-ft) of torque peaking at 5,500 RPM. Twist the throttle, and the CVT delivers acceleration that shames smaller-displacement rivals.

Key Highlights:
- Dual Power Modes: “Full Power” unleashes the beast, while “Rain Mode” tames throttle response for slippery conditions.
- Exhaust Note: The DOHC engine’s growl through its twin ports is addictive—a proper motorcycle soundtrack.
- Cooling Efficiency: Even in stop-and-go traffic, the liquid-cooling system keeps temps in check.

On the highway, the AK 550 cruises at 130 km/h (81 mph) with ease, and there’s still punch left for overtakes. The CVT’s lack of shift shocks makes it ideal for long hauls, though purists might miss manual gear changes.

Handling & Ride Experience: Sportbike Soul in a Scooter Body

The AK 550’s chassis is where engineering shines. The aluminum frame and near 50/50 weight distribution (dry weight: 210–226 kg / 463–498 lbs) give it agility that belies its size.

Suspension & Brakes:
- Front: 41mm inverted forks soak up bumps while maintaining razor-sharp feedback.
- Rear: The horizontal trailing arm suspension keeps the rear planted during hard cornering.
- Braking: Dual 270mm Brembo discs up front and a single 260mm rear disc, backed by Bosch 9.1 ABS, inspire confidence.

Throw it into a bend, and the AK 550 carves like a sportbike. The wide handlebars offer leverage, while the low center of gravity (aided by underbone frame design) makes transitions effortless. At 1580mm (62.2") wheelbase, stability isn’t sacrificed—this scooter tracks true even at triple-digit speeds.

Technology & Features: Smarter Than Your Average Scooter

Kymco packed the AK 550 with tech that rivals premium motorcycles:
- Noodoe Connectivity: This customizable digital dash integrates navigation, weather updates, and smartphone alerts.
- Keyless Ignition: Walk up, start up—no fumbling for keys.
- Full LED Lighting: From the aggressive headlights to the sleek taillights, visibility is top-notch.
- LAMS Approved: A boon for learners in markets like Australia and New Zealand.

The analog-style tachometer flanking the digital display is a nice touch, blending retro aesthetics with modern functionality.
