645cc Liquid-cooled DOHC 90-degree V-twin (Updated internals)
Petrol
Shift through all gears under moderate load, specifically checking for any hesitation or 'jumping' out of second gear, as this can be a sign of a worn gear selector fork on higher-mileage examples.
With the engine at operating temperature, listen closely for a rhythmic ticking noise from the top end; while the V-twin is naturally mechanical-sounding, excessive noise might suggest a need for a valve clearance inspection.
Perform several gentle stops using only the front brake to check for pulsing or vibration in the lever, which could indicate warped rotors or uneven pad wear after years of use.
Observe the idle stability once the engine is fully warmed up; a fluctuating idle could point to potential throttle body synchronization needs or vacuum line leaks common in bikes that have sat for extended periods.
Routine valve clearance check and spark plug replacement interval.
Major service milestone including coolant flush, air filter replacement, and a deep check of the timing chain tensioners.
Significant milestone requiring a thorough inspection of the suspension linkage bearings and steering head bearings.
Keep the drive chain clean and lubricated every 500-800km to ensure smooth power delivery and longevity of the sprockets.
Regularly inspect the coolant levels and condition, as the SV650 thrives when the cooling system is free of debris and properly flushed.
Monitor brake fluid color and levels; replacing the fluid every two years prevents moisture buildup and maintains that firm lever feel.
Check the battery terminals for signs of corrosion or looseness, as these bikes appreciate a solid, steady voltage for the fuel injection system.
Inspect the tires for squared-off profiles, which can significantly alter the SV's legendary agile handling characteristics.
Estimated repair costs if issues arise
As part of long-term ownership, these require periodic checks. If the technician finds they are out of specification, it involves removing camshafts, which is a labour-intensive task.
Depending on how the bike has been ridden, you might eventually need to budget for new fork seals and fresh oil, or an upgraded rear shock, to restore the factory-fresh handling.
If you notice the engine RPM rising without a proportional increase in speed, the clutch plates may be worn. This is a standard consumable item that will need replacing over the lifespan of the bike.
