Tools and Supplies Needed

  • Socket set (metric)
  • Torx bit set (for engine and body fasteners)
  • Oil drain pan
  • Contact cleaner or degreaser
  • Rags or shop towels
  • Replacement oil filter kit (OEM or quality equivalent)
  • Fresh engine oil (Motorex 10W-50 is factory spec)
  • New O-rings or crush washers (included with good oil change kits)
  • Funnel (for mess-free refills)
  • Service manual (optional but recommended)

Recommended Oil and Amount

  • Oil type: Motorex 10W-50 4T (fully synthetic or manufacturer-approved equivalent)
  • Capacity: 1.7–1.8 liters (1.8 l with filter change; always check visually at sight glass)

Service Interval

  • First change at 620 miles (or 1,000 km)
  • Then every 6,200 miles (or 10,000 km) thereafter

Step-by-Step Oil Change Process

  • Preparation:
    Ensure the engine is warm but not hot—run the bike for five minutes, then shut it off to allow oil to drain effectively. Park the Supermoto on a stand so it is level.
  • Remove Skid Plate:
    If equipped, remove the engine guard or skid plate for clear access to the underside of the engine. Use your Torx or socket set as needed.
  • Clean the Area:
    Spray contact cleaner around the oil fill cap, drain plugs, and filter cover to prevent debris from entering the engine.
  • Remove Oil Fill Cap:
    Opening the fill cap (found on the right side at the top of the clutch cover) allows oil to drain more smoothly.
  • Drain the Oil:
    • Place your drain pan under the engine.
    • Locate and remove the main oil drain plug, usually just below the shift lever (left side). Allow the oil to fully drain.
    • Remove the secondary drain plug with an attached oil screen near the main drain. Pull the oil screen out gently with pliers.
    • Clean both screens thoroughly with contact cleaner, inspect for debris and reinstall if screens are undamaged.
  • Replace the Oil Filter:
    • Remove the filter cover bolts (right side of engine).
    • Take out the old filter, noting its orientation. Clean out the filter cavity.
    • Install the new filter, ensuring it's seated correctly and replace old O-rings with new ones.
  • Reinstall Drain Plugs and Filter Cover:
    • Use new crush washers or O-rings on plugs and filter cover if provided.
    • Torque all bolts to manufacturer specification (see service manual or cover for details—do not overtighten, especially plastic or aluminum plugs).
  • Add Fresh Oil:
    • Using a funnel, pour in about 1.5 liters of oil.
    • Pause and check the sight glass (right case)—add oil gradually until the level is between the sight glass lines.
    • Total oil typically is 1.7–1.8 liters after draining engine and changing the filter. Do not overfill.
  • Prime and Top Off:
    • Start the engine and let it idle for one minute to circulate oil (sight glass level will briefly drop).
    • Shut off, let it settle for a couple of minutes, recheck the oil level, and carefully add more as needed to bring it between the markers.
  • Clean Up and Final Checks:
    • Check for oil leaks around the drain plugs and filter housing.
    • Wipe any spilled oil from the engine.
    • Reinstall the skid plate.

Model-Specific Notes and Call-Outs

  • 701 Supermoto & Enduro share the same engine and oil change process for 2016–2022.
    Pay special attention to plastic fittings like the filler cap—do not overtighten to avoid stripping threads or cracking.
  • Primary drain plugs include an oil screen—always inspect and clean this during changes, as debris may accumulate.
  • Oil sight glass is sometimes hard to read—set the bike upright (not on the side stand) and aim for the middle of the sight window.
  • Refill oil in stages: Fill most of the oil, start and idle the bike, and then add the remainder. This ensures the filter and passages are saturated and prevents overfilling.

Pro Tips

  • Always double-check for loose bolts and leftover parts before riding.
  • Write down your oil change mileage; it helps in maintaining the recommended intervals.
  • Inspect the old oil for excessive metallic particles—a sign of abnormal wear.
  • Dispose of used oil and filters responsibly at a certified recycling center.
