Paper Type Paper Type: N/A (Digital PDF format). ⚙️ Engine Specifications Primary Engine Engine Family: MA50 Engine Type: Two-stroke (common for this engine designation in Aprilia models of the era, requires verification based on specific vehicle model). Displacement: Likely around 50cc (typical for MA50 designation, e.g., Aprilia SR50). Performance Horsepower: Approximately 4-7 HP (typical for 50cc two-stroke engines of this class, actual figures vary by specific application and tuning). Torque: Low to moderate torque output, optimized for low-speed acceleration in scooters/mopeds. Fuel System Fuel Delivery: Likely carburetor-fed, with potential for EFI in later or more advanced models. Fuel Type: Unleaded gasoline (e.g., 95 RON). Lubrication Lubrication Type: Premix or Automatic Oil Injection (common for two-strokes, manual will detail which system is used). 🔧 Transmission Standard Transmission Type: Automatic (Continuously Variable Transmission - CVT is standard on most Aprilia scooters of this era). Optional Manual Transaxle: The manual lists 'Manual Transaxle System,' which is unusual for a 50cc scooter engine but could refer to specific variants or a broader classification. Typically, MA50 would be associated with a CVT. Features Gear Selection: Automatic variator drive and clutch system for seamless gear changes. 📐 Dimensions Exterior Vehicle Type: Scooter/Moped (assumed based on engine application). Weights Dry Weight: Estimated 80-100 kg (typical for 50cc scooters). 🛡️ Safety Features Ratings Crash Test Data: Not applicable for this manual; safety information pertains to the vehicle's design and components. Active Features Braking System: Front and rear braking systems (details in coverage). Passive Features Frame Construction: Steel frame, fairing panels for protection and aerodynamics. 💡...
