645cc 90° V-twin (Fuel Injected) - Naked/S-model
Petrol
When moving off in first gear, listen for any clunking or hesitation from the front sprocket area, as the drive chain and sprocket sets on these can wear out if they haven't been kept well-lubricated by the previous owner.
While riding at low speeds, gently squeeze the front brake and feel for any pulsing or vibration through the lever, which might indicate that the brake discs have become slightly warped over time.
Before starting the cold engine, check the condition of the radiator fins for any heavy debris or signs of past minor 'tip-overs,' as the radiator is quite exposed on the naked SV650 model.
During the ride, monitor the temperature gauge; if the needle climbs unusually fast in traffic, it is worth checking if the cooling fan kicks in as intended, as the cooling system on these bikes is robust but relies on the fan for city riding.
Usually marks a significant service where valve clearances should be inspected and air filters replaced.
A major interval where spark plugs and coolant hoses should be closely examined for signs of aging.
At this point, you might consider checking the condition of the fuel pump internal filter and the overall state of the electrical connectors.
Check the engine oil level using the sight glass on the right side of the engine while the bike is held upright.
Inspect the chain tension and lubrication; the SV's V-twin torque can stretch chains if they aren't adjusted to the manual's specifications.
Verify the state of the rear brake fluid reservoir, ensuring the fluid is clear rather than dark brown or cloudy.
Test all electrical switches and turn signals, as the handlebar controls can occasionally gather a bit of moisture or grime.
Look over the coolant reservoir to ensure the level is between the markers when the engine is cold.
Estimated repair costs if issues arise
In bikes of this age, the stator can occasionally show signs of wear. If you notice the battery struggling to hold a charge, you might eventually need to budget for a stator replacement or a regulator/rectifier upgrade.
The front forks on the 2nd generation SV are known to be quite soft. Depending on your riding style, you may eventually decide to budget for a professional fork rebuild with heavier oil or upgraded springs to improve handling.
If you notice the engine revs rising without a corresponding increase in speed under hard acceleration, the clutch plates may be wearing thin and could require replacement down the road.
