Type 50Cc:
Likely a 2-stroke, single-cylinder, air-cooled engine (common for this displacement and era).
Type 100Cc:
Likely a 4-stroke, single-cylinder engine, potentially air or liquid-cooled depending on specific configuration (e.g., Piaggio LEADER engine family variants).
Horsepower 50Cc:
Typically in the range of 4-5 HP, governed by regulations.
Horsepower 100Cc:
Typically in the range of 7-9 HP, offering a significant performance advantage over the 50cc version.
Torque Characteristics:
Designed for strong low-end and mid-range torque for responsive acceleration in urban environments.
Carburetor 50Cc:
Likely a Dell'Orto PHVA or similar 17.5mm carburetor.
Fuel Delivery 100Cc:
May utilize a slightly larger carburetor or potentially fuel injection on some later or specific market versions, though carburetor is more probable for 2006 100cc.
Oil Mixing 50Cc:
Premix or separate oil injection system for the 2-stroke engine.
Oil Type 100Cc:
Likely requires a SAE 10W-40 or similar API SG, SH, SJ, SL rated 4-stroke scooter oil.
Type:
Automatic, CVT (Continuously Variable Transmission)
Drive System:
Belt-driven final drive via CVT unit.
Gear Ratios:
Continuously variable, adjusting ratios for optimal engine performance across the speed range.
Transmission Oil Type:
Likely requires a specific SAE 80W-90 gear oil for the reduction gear. Specification to be confirmed in manual.
Length:
Specific dimensions not provided, but typically compact for urban maneuverability.
Width:
Specific dimensions not provided, designed for ease of navigating traffic.
Dry Weight:
Typically around 100-110 kg (220-243 lbs) for the 100cc version, slightly less for the 50cc.
Fuel Capacity:
Likely around 7-8 liters (approx. 1.8-2.1 US gallons).
Crash Test Results:
Scooters of this era were generally not subjected to standardized crash testing like automobiles. Safety relies on rider skill and vehicle design for stability.
Braking System:
Disc brake front and rear (common for Quasar), providing good stopping power. ABS was not a typical feature on models of this size and era.
Lighting:
Integrated headlights, taillights, and turn signals for visibility.
Frame Construction:
Steel frame for rigidity and durability.
Tires:

No electronic stability control systems expected on this model.
Usb Charging:
Not typically featured on scooters of this era.
Oil Change Interval:
Typically every 3,000-5,000 km (1,800-3,000 miles) for 4-stroke engines, or as per manual recommendation. 2-stroke models require regular checking of oil levels for the injection system.
Spark Plug Replacement:
Approximately every 5,000-10,000 km (3,000-6,000 miles), depending on plug type and usage.
Air Filter Cleaning Replacement:
Regular inspection and cleaning/replacement, typically every 5,000-8,000 km (3,000-5,000 miles).
Cvt Belt Inspection Replacement:
