Yamaha YP 400 Majesty (2004–2015): A Maxi-Scooter Built for Royal Comfort
Introduction
The Yamaha YP 400 Majesty isn’t just a scooter—it’s a statement. For over a decade, this maxi-scooter reigned as a benchmark for riders seeking a blend of urban practicality, touring comfort, and fuss-free performance. Designed to bridge the gap between nimble city commuters and highway-capable machines, the Majesty 400 carved out a loyal following among riders who refused to compromise. After spending a week with this two-wheeled throne, it’s easy to see why it earned its regal name.
With its 395cc liquid-cooled engine, cavernous storage, and plush seating, the Majesty feels like a Swiss Army knife for riders who demand versatility. Whether slicing through traffic or gliding along coastal roads, this Yamaha delivers a ride that’s both relaxed and invigorating. Let’s dive into what makes this generation of the Majesty a standout—even years after its debut.
Design & Ergonomics: Function Meets Elegance
The Majesty’s design is unapologetically bold. Its sweeping bodywork, crowned by an optional windscreen (on later models), gives it a commanding presence. The 2230 mm (87.8 in) overall length and 1565 mm (61.6 in) wheelbase create a stable platform, while the die-cast aluminum frame keeps the weight manageable at 211–223 kg (465–492 lbs) depending on the model.
Key Features:
- Storage King: The lockable underseat compartment swallows 60 liters (16 gallons)—enough for two full-face helmets or a week’s groceries. Additional compartments in later models add even more utility.
- Accessible Ergonomics: A 750–762 mm (29.5–30 in) seat height accommodates riders of all sizes, and the floorboard provides ample legroom. The contoured “king and queen” seat with integrated passenger backrest (standard on post-2007 models) is a masterclass in comfort.
- Wheels & Suspension: 14-inch front and 13-inch rear wheels strike a balance between agility and stability. The 41mm telescopic forks and twin rear shocks (adjustable on ABS variants) absorb bumps with grace, even on poorly maintained roads.
Color options evolved over the years, from vibrant Candy Red (2004) to understated Titanium and Stealth Gray (2010s), ensuring the Majesty never looked out of place in urban jungles or suburban driveways.
Performance: Smooth Operator
At the heart of the Majesty lies a 395cc single-cylinder engine that’s as refined as it is robust. The DOHC, 4-valve setup with electronic fuel injection (EFI) pumps out 33.5–35 HP (25–25.7 kW) and 36.3–37 Nm (26.8–27.3 lb-ft) of torque. While these numbers might not set your hair on fire, the Majesty’s strength lies in its delivery.
Riding Impressions:
- City Slicker: The automatic CVT transmission eliminates clutch hassle, making stop-and-go traffic a breeze. Acceleration from 0–60 km/h (0–37 mph) is brisk, and the belt-driven final drive operates whisper-quiet.
- Highway Cred: At 100 km/h (62 mph), the engine hums at a relaxed 6,000 RPM. Top speed hovers around 135–140 km/h (84–87 mph)—enough for confident highway overtakes.
- Fuel Efficiency: Averaging 4.7 L/100 km (50 mpg), the 14-liter (3.7-gallon) tank delivers a 300 km (186-mile) range.
Yamaha tweaked the engine internals in 2007, revising the piston, ECU, and exhaust for smoother power delivery. Later ABS models (2010–2015) added an extra layer of safety with combined braking systems, ideal for wet conditions.
Comfort & Practicality: Long-Distance Luxury
The Majesty’s cabin-like ergonomics make it feel like a mobile living room. During a 200-km (124-mile) test ride, fatigue never crept in—thanks to the upright riding position and generous seat padding.
Standout Comfort Features:
- Wind Protection: The tall windscreen (standard on Grand Majesty trims) deflects airflow over the rider’s head, reducing buffeting at speed.
- Heated Grips (Optional): A godsend in chilly weather, though aftermarket installation is recommended for pre-2010 models.
- Instrumentation: Analog speedometer and digital display (clock, fuel gauge, trip meter) are legible day or night.
Storage isn’t an afterthought here. Beyond the underseat compartment, hook points under the handlebars and a lockable glovebox (on ABS variants) make grocery runs or weekend getaways stress-free.
Competition: How the Majesty Stacks Up
The maxi-scooter segment is fiercely competitive. Here’s how the Majesty 400 holds its ground:
1. Honda Silver Wing 600
- Pros: More power (58 HP), larger storage.
- Cons: Heavier (244 kg / 538 lbs), thirstier (5.5 L/100 km / 43 mpg).
- Verdict: The Silver Wing is a touring beast but overkill for city dwellers.
2. Suzuki Burgman 400
- Pros: Slightly sharper handling, optional ABS earlier (2007).
- Cons: Cramped seat, fussy transmission in early models.
- Verdict: A direct rival, but the Majesty’s seating and storage give it an edge.
3. BMW C 400 X
- Pros: Modern tech (TFT display, connectivity), lighter weight.
- Cons: Higher maintenance costs, smaller storage.
- Verdict: The BMW appeals to tech enthusiasts, but the Majesty wins on value.
Yamaha’s focus on simplicity and reliability makes the Majesty a “set it and forget it” option compared to more complex rivals.
Maintenance: Keeping Your Majesty Road-Ready
Owners praise the YP 400’s durability, but proactive care ensures longevity. Here’s what to prioritize:
Key Maintenance Tips:
- Belt Drive: Replace the V-belt every 24,000 km (15,000 miles). Look for fraying or glazing.
- Oil Changes: Use SAE 10W-40 every 6,000 km (3,700 miles). Capacity: 1.7L (1.8 quarts) with filter.
- Cooling System: Flush coolant every 2 years or 30,000 km (18,600 miles). Capacity: 1.57L (1.66 quarts).
- Valve Adjustments: Check every 12,000 km (7,500 miles). Intake: 0.15–0.20 mm (0.006–0.008 in), exhaust: 0.25–0.30 mm (0.010–0.012 in).
- Tires: Maintain 2.0 bar (29 psi) front / 2.5 bar (36 psi) rear. The 120/80-14 front and 150/70-13 rear tires wear evenly with proper inflation.
Common Upgrades:
- Aftermarket Windshields: Taller screens improve wind protection.
- Suspension Upgrades: Progressive-rate springs enhance handling for heavier riders.
- LED Lighting: Boost visibility with modern bulb replacements.
