The motorcycle fuel tank stores fuel (mainly gasoline) to provide continuous power for the engine. It also contributes significantly to the motorcycle's exterior design, with its capacity and shape affecting both vehicle endurance and overall style.

Box Body

• Material:
  • Metal (steel/aluminum alloy): Traditional fuel tanks made of cold-rolled steel plates with anti-rust treatment (galvanizing, spraying). High strength and impact resistance but heavier.
  • Engineering plastics: Modern models use materials like high-density polyethylene (HDPE) - 50% lighter than metal, corrosion-resistant, flexible in shape, and safer (spark-resistant).
• Shape:
  • Straddle-type motorcycles: "Teardrop" or "angular" shapes for better leg fit and riding control
  • Scooters: Flat tanks hidden under seat buckets
  • Retro models: "Hump-shaped" or "round" designs for classic styling

Accessories

• Fuel tank cap: Standard screw caps or anti-theft locking caps; some high-end models feature smart caps with fuel indication
• Vent: Maintains air pressure balance to prevent fuel evaporation issues
• Fuel switch: Controls fuel flow with "on", "off", and "standby" positions for low-fuel emergencies
• Fuel sensor: Monitors fuel levels for electronic fuel gauge models
• Wave-breaking board: Internal partition reduces fuel sloshing during operation

• Standard capacity:
  • Straddle motorcycles: 8-20 liters (300-600 km range)
  • Scooters: 5-10 liters (200-300 km range)
  • Off-road/rally vehicles: 20-30+ liters for extended endurance
• Factors affecting capacity: Engine fuel consumption, road conditions, tank shape ("virtual volume" in special designs)

• Lightweight: Increasing use of plastic fuel tanks
• Integration: Combined tank-frame designs (e.g., aluminum alloy frame tanks) for structural strength
• Personalization: Custom tank stickers, paintings, or metal carvings for modification

The meter is the core dashboard component displaying real-time speed and mileage. Advanced models may include tachometers, fuel indicators, fault alarms, and other vehicle status information.

1. Mechanical Pointer Meter

• Structure: Flexible shaft (wire drive), worm gear mechanism, pointer, and dial
• Operation: Wheel rotation drives flexible shaft, which moves the pointer via gear transmission
• Features: Cost-effective and simple to maintain, but prone to accuracy issues from shaft wear and high-speed jitter

2. Electronic Digital Meter

• Structure: Hall effect/magnetoelectric sensors, ECU, LCD/LED display
• Operation: Sensors monitor wheel speed, ECU calculates values, digital display shows results
• Features: High accuracy, information-rich displays (fuel consumption, average speed), backlight adjustment, some with TFT screens and Bluetooth connectivity

3. Hybrid Meter

Combines mechanical pointers with digital displays for retro-modern functionality

• Speed display: km/h or mph, typically 0-200 km/h range (varies by engine size)
• Mileage display:
  • Total mileage (Odometer): Permanent record
  • Trip mileage: Resettable for individual journeys
• Additional functions: Tachometer, fuel/water temperature indicators, ABS/turn signal warnings

• Location: Typically center handlebar or upper connecting plate for optimal visibility
• Protection: Scratch-resistant acrylic/glass with IP65+ waterproof/dustproof rating
• Modification trends: Round mechanical for retro models, full-color LCD for modern street/racing bikes

• Mechanical meters: Flexible shaft breakage, gear wear - requires regular lubrication
• Electronic meters: Sensor failure, backlight damage - needs professional circuit diagnosis
• Calibration: Required when changing tire specifications to maintain speed/mileage accuracy
