Fuel System Fuel System: Carbureted (likely Dell'Orto or Bing, specific models may vary). Ignition Ignition System: Magneto ignition (likely CDI or points-based depending on year/model). Performance Horsepower Torque: Varies by displacement and specific model; typically high power-to-weight ratio for their class. Specific figures require model year identification. Lubrication Lubrication System: Two-stroke pre-mix lubrication. Cylinder Design Cylinder Design: Monobloc cylinder construction common in two-stroke engines. 🔧 Transmission Type Transmission Type: Manual transmission (number of gears likely 5 or 6). Clutch Clutch Type: Wet multi-plate clutch (typical). Gear Ratios Gear Ratios: Specific gear ratios are model-dependent and would be detailed within the manual. Features Transmission Features: Close-ratio gearboxes typical for performance applications. 📐 Dimensions Weights Dry Weight: Varies significantly by model and year; early models were lightweight (e.g., 90-100 kg range for 250s). Total Weight: Weight figures would be specific to each model variant (250, 400, 440, 501). Wheelbase Wheelbase: Varies by model, typically around 1400-1500 mm. Seat Height Seat Height: Varies by model, designed for off-road control. 🛡️ Safety Features Features Braking System: Drum brakes (front and rear) on earlier models, potentially disc brakes on later models for specific variants. Suspension Front: Telescopic forks (e.g., Marzocchi, Betor, Ceriani). Suspension Rear: Twin shock absorbers, swingarm (Maico's distinctive monoshock system emerged later). Frame Type: Steel frame (typically double cradle or similar off-road design). Tire Sizes: Typical off-road sizes (e.g., front 3.00-21, rear 4.00-18 or 4.50-18, but specific recommendations in manual). 💡 Technology Features Infotainment Infotainment System: N/A (basic instrumentation: speedometer, odometer, engine kill switch). Driver Assistance Driver Assistance Features: N/A (mechanical systems only). 🔧 Maintenance Service Intervals Service Intervals: Typical for vintage off-road motorcycles: frequent checks of chain tension, tire pressure, air filter cleaning/replacement, and spark plug inspection/replacement. Engine oil changes for gearbox oil are crucial and frequent. Spark Plug Maintenance: Regular inspection and gap adjustment/replacement. Chain Maintenance: Regular cleaning, lubrication, and tension adjustment.
