Configuration:
225cc (specific configuration like single, twin, etc. not detailed, but '225' strongly suggests a single-cylinder engine common in this displacement class for Yamaha.)
Engine Type:
Likely 4-stroke, air-cooled or liquid-cooled single cylinder (common for 225cc displacement in this era).
Horsepower:
Estimated 15-20 HP (typical for this displacement, specific figures not provided in product info).
Torque:
Estimated 15-20 Nm (typical for this displacement, specific figures not provided in product info).
Fuel Delivery:
Likely Carburetor (Mikuni VM or similar) or early Fuel Injection system depending on specific model variant.
Fuel Type:
Unleaded gasoline (Octane rating specification would be in the manual).
Infotainment System:
N/A (Motorcycles of this era generally did not feature complex infotainment systems. Focus would be on instrumentation.)
Rider Aids:
Limited rider aids, primarily focused on mechanical reliability and standard safety features like effective braking. ABS may have been an option on some later models, detailed in manual.
Connectivity Features:
N/A (No Bluetooth or smart device integration typical for this era of motorcycle).
Dashboard Features:
Analog or digital tachometer, speedometer, odometer, trip meter, fuel gauge (if equipped), and indicator lights for turn signals, oil pressure, and neutral.
Oil Change Interval:
Typically every 3,000-5,000 km or 6-12 months, but specific interval is detailed in the manual.
Spark Plug Replacement:
Recommended every 10,000-15,000 km, but the manual provides precise intervals and specifications.
Valve Clearance Check:
Typically every 10,000-20,000 km, critical for engine performance and longevity. Manual provides exact checks and adjustment procedures.
Engine Oil Type:
Yamalube 4-stroke motorcycle oil, SAE 10W-40, API SG or higher, JASO MA certified (verify in manual).
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid (verify in manual).
Coolant Type:
If liquid-cooled: Ethylene glycol-based antifreeze with demineralized water (50/50 mix). Specific type and capacity in manual.
Common Wear Items:
Chain and sprockets, brake pads, tires, clutch plates, fork seals, and battery are common wear items requiring regular inspection and replacement.
Electrical Component Aging:
Aging electrical components like rectifier/regulators or ignition coils can be prone to failure on motorcycles of this age; the manual aids in diagnosis.
