Full schedule
Intervals follow manufacturer-typical recommendations for motorcycles of this class. Verify against your owner's manual.
| Service | Interval | Est. cost | Notes |
|---|---|---|---|
| Chain Clean, Lube & Adjust | Every 500 mi or 2 mo | $20–60 | Clean, lube and tension the chain often: off-road grit wears a dual-sport chain fast; a dry or loose chain eats sprockets |
| Oil Change | Every 4,000 mi or 12 mo | $40–100 | Engine oil and filter: a hard-worked small single shears oil fast, especially in the dirt; never exceed 12 months |
| Tire Inspection & Age Check | Every 4,000 mi or 12 mo | $20–60 | Check tread, pressure and casing age; knobby dual-sport tires wear unevenly and rubber hardens with age even at low miles |
| Brake Pads Inspection | Every 5,000 mi or 12 mo | $25–90 | Inspect pad thickness and rotor wear; mud and sand can grind pads down quickly, so check more often after dirt rides |
| Air Filter | Every 8,000 mi or 12 mo | $25–80 | Clean or replace the air filter; on a dual-sport ridden in dust do this far more often than the interval suggests |
| Battery Test | Every 8,000 mi or 12 mo | $10–40 | Load-test the battery and check charging; small bikes sit between rides and vibration plus cold shorten battery life |
| Valve Clearance Check | Every 12,000 mi or 2 yr | $130–320 | Check and shim the valve clearances. Small high-revving singles tighten up sooner than big multis; skipping it burns valves |
| Brake Fluid Flush | Every 12,000 mi or 2 yr | $60–140 | Flush front and rear brake fluid every ~2 years; it absorbs water and fades under hard trail braking |
| Fork Oil Change | Every 12,000 mi or 2 yr | $120–280 | Refresh fork oil and seals; off-road use contaminates the oil and blows seals sooner than street-only riding |
| Steering & Wheel Bearings Check | Every 12,000 mi or 2 yr | $40–120 | Check steering-head and wheel bearings for play; jumps, ruts and water crossings on a dual-sport wear them out early |
| Chain & Sprocket Replacement | Every 15,000 mi or 5 yr | $150–350 | Replace chain and both sprockets as a set; dirt riding wears them quicker, and a worn set will destroy a new chain |
| Spark Plug | Every 16,000 mi or 2 yr | $20–70 | Single-cylinder means one plug: cheap and quick; a fouled plug on a thumper shows up as hard starting |
| Coolant Change | Every 24,000 mi or 2 yr | $70–150 | Flush and refill coolant on this liquid-cooled engine; old coolant loses corrosion protection and lets the radiator scale up |
