Diagnostic Port:
On-board diagnostics (OBD) port for fault code reading and data logging, essential for advanced troubleshooting.
Oil Change:
Recommended every 6,000 km (3,700 miles) or annually, whichever comes first.
Air Filter:
Inspect every 6,000 km (3,700 miles), replace as needed or at major service intervals.
Spark Plugs:
Replace every 12,000 km (7,500 miles) or as per manual recommendation.
Valve Check:
Recommended at 12,000 km (7,500 miles) or as per manual recommendation for initial checks, then as needed.
Cv Belt Inspection:
Inspect condition and tension regularly, typically recommended replacement interval around 20,000-30,000 km (12,500-18,500 miles), refer to manual for exact specification.
Engine Oil:
SAE 10W-40, API SG or higher, JASO MA certified. Capacity approx. 2.4 Liters with filter change.
Coolant:
Mixture of distilled water and ethylene glycol based antifreeze (50/50 ratio). Ensure motorcycle-specific coolant compatibility.
Cv Belt Wear:
CVT belt wear can be a factor; proper maintenance and riding style are crucial. Manual provides inspection criteria.
Electrical Connections:
Some users report potential for corrosion in electrical connectors if exposed to harsh weather; manual offers guidance on inspection and protection.
Rear Shock ABSorber:
While generally robust, occasional wear on the rear shock seals or damping performance degradation over time may necessitate service or replacement. Manual details servicing.
