Suspension Features: Upside-down (USD) front forks, Monoshock rear suspension with adjustable preload. Passive Features Frame Construction: Aluminum twin-spar frame for rigidity and light weight. 💡 Technology Features Infotainment Instrument Cluster: Digital/Analog combination cluster, typically including tachometer, speedometer, odometer, trip meter, coolant temperature warning light, and neutral indicator. Driver Assistance ABS: ABS was not standard or widely available on most RS125 models in this period; it was more common on later or different model lines. Connectivity Connectivity Features: N/A (Motorcycle of this era typically lacks advanced connectivity features). 🔧 Maintenance Service Intervals Oil Change Interval: Refer to manual for specific intervals, typically based on mileage or time. For 2-stroke, crucial for gearbox and potentially injection system. Spark Plug Replacement: Refer to manual, typically every 5,000-10,000 km depending on plug type and usage. Chain And Sprocket Inspection: Regular inspection for wear, adjustment, and lubrication is critical. Top End Rebuild: For performance-oriented 2-strokes like the Rotax 122, top-end rebuilds (piston, rings, cylinder) are typically recommended between 10,000-20,000 km, depending on riding style and maintenance. Fluid Specifications Engine Oil 2T: High-quality 2-stroke synthetic oil, specifically formulated for liquid-cooled high-performance engines. (Refer to manual for specific API/JASO ratings). Coolant Type: Ethylene glycol-based antifreeze coolant, mixed with distilled water (typically 50/50). (Refer to manual for specific type/color). Brake Fluid Type: DOT 4 or DOT 5.1 (Refer to manual for exact specification). Gearbox Oil: Specific motorcycle gear oil. (Refer to manual for viscosity and API rating, e.g., SAE 75W-90 or SAE 80W-90). Known Issues Common Wear Items: Clutch plates, piston rings, exhaust valve mechanism, wheel bearings, brake pads. Performance Tuning Considerations: Proper jetting, exhaust valve operation, and ignition timing are critical for optimal 2-stroke performance and longevity. Overheating can be an issue if cooling system is neglected. 📚 Vehicle History Brand Heritage Aprilia Legacy: Aprilia has...
