Aprilia RXV / SXV

Additional Notes

• The Aprilia RXV / SXV cooling system capacity is 1.1 liters across both the 450 and 550 variants, a figure that applies uniformly regardless of use condition or model year within the specified ranges.
• For the RXV / SXV 450 under normal use conditions, the cooling system check interval is set at 3,000 km, reflecting a distance-based maintenance schedule suited to standard riding environments.
• Under severe use conditions, the 450's coolant check interval shifts from a distance-based measure to a time-based one, with a check required every 15 hours of operation rather than every 3,000 km.
• A first-change-only interval of 500 km applies to the RXV / SXV 450 under normal use, meaning the initial coolant inspection after a new fill or rebuild occurs significantly earlier than subsequent scheduled checks.
• When severe use and first-change-only conditions are combined on the 450, the earliest check interval drops to just 3 hours of operation, the shortest interval specified across all configurations in the data.
• The RXV / SXV 550 shares an identical 1.1-liter cooling system capacity with the 450, and all four use-condition intervals mirror those of the 450 exactly, including the 3,000 km normal check, the 15-hour severe check, the 500 km first-change-only check, and the 3-hour severe first-change-only check.
• The 550 variant's model year coverage begins in 2005, one year earlier than the 450's 2006 start, while the 450's coverage ends in 2012 compared to the 550's range starting in 2005.
• The dual-interval structure across all rows, separating distance-based and hour-based checks, reflects the dual-purpose nature of the RXV and SXV platforms, which are designed for both road and off-road competition use where odometer readings alone may not capture actual engine load.
