Service schedule
The intervals MotoMaintain uses for the RC 8C, whichever comes first. Track them in MotoMaintain →
Engine Oil & FilterFresh oil and a new filter. The single most important service for engine life.
Every 4,000 mi or 12 mo Chain Clean & LubeClean and re-lube the chain. Do it more often in wet or dusty riding.
Every 500 mi Chain Tension & InspectionCheck chain slack, adjust if needed, inspect sprockets for wear.
Every 4,000 mi Air FilterInspect and replace the air filter. More often if you run a high-flow filter.
Every 12,000 mi Spark PlugsReplace spark plugs. Iridium plugs typically last the full interval.
Every 16,000 mi Brake FluidFlush and replace brake fluid. It absorbs moisture over time regardless of miles.
Every 24 mo CoolantDrain and replace engine coolant.
Every 24,000 mi or 36 mo Valve Clearance CheckMeasure valve clearances and shim as needed. A big, interval-based service — intervals vary a lot by engine.
Every 16,000 mi Brake PadsInspect pad thickness. Replacement is wear-based — track and aggressive riding wears them faster.
Check every 4,000 mi TiresInspect tread depth, pressure, and condition. Replacement is wear-based.
Check every 3,000 mi Full Service / InspectionComprehensive dealer-style inspection: fasteners, bearings, suspension, electrical, fluids.
Every 8,000 mi or 12 mo
