Engine Oil Change:
Typically every 10-15 hours of riding or annually. Consult manual for specific recommendations.
Air Filter Cleaning:
Recommended after every few rides, especially in dusty conditions. More frequently than oil changes.
Valve Clearance Check:
Typically every 20-30 hours of riding. Crucial for engine performance and longevity.
Chain Maintenance:
Lubricate and adjust chain every 5-10 hours of riding or as needed.
Engine Oil:
KTM recommends specific grades of synthetic motorcycle oil. Consult manual for viscosity (e.g., 10W-50, 15W-50) and API/JASO standards.
Coolant:
Ethylene glycol based coolant, typically a 50/50 mix with distilled water. Check manual for exact specifications and capacity.
Brake Fluid:
DOT 4 or DOT 5.1 recommended. Always use fresh fluid.
Fork Oil:
Specific viscosity and fill level are critical for suspension performance. Manual will specify (e.g., WP Suspension Fluid, or equivalent SAE ratings).
Common Wear Items:
Clutch plates, wheel bearings, steering head bearings, fork seals, swingarm bearings, brake pads.
Engine Specifics:
Valve seat wear can occur with hard use; regular checks are vital. Carburetor tuning may be required for altitude or temperature changes.
Cooling System Potential:
Overheating if coolant is low or system is not properly bled. Inspect hoses for leaks.
