638cc Parallel Twin - Standard/Executive model
Petrol
Shift into manual mode and cycle through the gears. If the display flashes 'F1' or you feel clunky hesitation, this suggests the CVT gear position sensor might need attention.
Accelerate from a standstill to 40km/h. Listen for a metallic rattling sound from the transmission casing, as this can indicate the CVT primary pulley belt may be reaching the end of its service life.
Check this by idling the bike on the center stand. Observe the engine vibration; excessive shuddering at low RPM can be a sign that the clutch shoes are becoming glazed or worn.
Before your ride, test the ABS (if equipped) by performing a controlled stop on a safe surface. A pulsing lever confirms operation, but a dead lever suggests the modulator may need professional attention.
Usually marks the first major valve clearance check and spark plug replacement.
The big one for the CVT; checking the belt and rollers is recommended to ensure long-term reliability.
General chassis health check, including wheel bearings and steering head bearings.
Keep a close eye on the final drive oil levels; they are often overlooked but vital for the AN650.
Regularly lubricate the side stand and center stand pivot points to prevent them from seizing in NZ's coastal air.
Ensure your battery terminals are tight and clean, as these bikes are quite sensitive to voltage drops.
Stay on top of coolant flushes to prevent potential corrosion in the radiator system.
Check the brake fluid color periodically to ensure the system remains responsive for our winding NZ roads.
Estimated repair costs if issues arise
While the AN650 is a fantastic tourer, the complex CVT system is its heart. If this component needs attention in the future, the estimated cost in NZ is higher than standard chain-drive bikes due to parts and labor complexity.
Depending on how the bike has been ridden in traffic, you might eventually need to budget for a clutch rebuild to restore smooth take-offs.
Given the weight of the AN650, steering head bearings can wear over time, causing a slight 'notch' in the steering. It is a common maintenance item for a bike of this age.
