Step-by-Step Maintenance Tips
1. Engine Oil & Filter Change
Warm up engine for 3–5 minutes
Drain old oil completely
Replace OEM filter with approved filter
Refill with recommended oil type/grade
Check oil level after first ride
Pro Tip: Always choose oils with JASO MA2 rating for optimal clutch performance.
2. Valve Clearance Adjustment
The 1,301cc engine uses shim-type adjustments — not easily inspected without tools. For best results, have a certified KTM technician perform this service – or use a torque wrench and service manual if you’re qualified.
Official KTM manuals available here:
3. Chain Tension & Drive Inspection
Clean chain every 300–500 miles
Measure slack
Lube with quality chain lube after every rain
4. Brake & Suspension
Replace brake fluid every two years
Inspect pads at each service interval
Suspension tune-ups after heavy touring or trail riding
