No advanced connectivity features like Bluetooth or smartphone integration are typically present on this model.
Headlight Type:
Likely Halogen bulbs for headlight and taillight.
Oil Change:
Recommended every 3,000-5,000 km or annually for 4-stroke variants; for 2-stroke, focus is on oil injection system health and premix quality, with periodic checks recommended.
Spark Plug Replacement:
Typically every 5,000-8,000 km, or as per manual recommendations for specific plug type.
Air Filter Cleaning Replacement:
Inspect and clean every 3,000 km; replace as needed or every 6,000-10,000 km.
