Shop parts for a 2021 Husqvarna 701 Supermoto Dirt Bike.

Changing the oil in your 2021 Husqvarna 701 Supermoto is key to ensuring engine longevity and high performance. This guide provides a step-by-step process, lists the specific tools needed, and highlights important call-outs exclusive to this model year. Let's get started.

Tools and Parts Needed

  • KTM 690/Husqvarna 701 Oil Filter Kit (includes filters, oil screens, gaskets)
  • 2 liters of Motorex 10W/50 synthetic oil (as specified by Husqvarna)
  • Ratchet with 13mm socket
  • T30 Torx/Star Bit Socket (or 8mm socket for some plugs)
  • Drain pan
  • Funnel
  • Rags and cleaner (for spills and wiping)
  • Torque wrench (for accurate tightening)
  • Needle-nose pliers or a hook tool (for pulling out oil screens)
  • Replacement crush washers/sealing rings (often included in filter kits)

Preparation

  • Warm up your engine for 2–3 minutes. This helps the oil flow out smoothly.
  • Place the bike on a stand or securely upright on level ground.
  • Position your drain pan under the engine.
  • Make sure you have all your tools and supplies ready and within reach.

Step-by-Step Instructions

  • Remove the Engine Guard:
    • Most 701 Supermotos are equipped with an engine guard or skid plate. Remove this first to access the oil drain plugs.
      Tip: The process is the same for both Enduro and Supermoto versions of the 701.
  • Clean Around Filler Cap and Remove It:
    • Use a rag and contact cleaner to remove any debris around the oil filler cap (top of the clutch cover). Unscrew the cap and set it aside.
  • Drain the Old Oil:
    • Locate the main oil drain plug below the foot shifter (left side, bottom of engine) and remove it using the 13mm socket.
    • Allow the majority of the oil to drain completely.
    • A second plug with either a T30 Torx or 8mm socket is located nearby. Remove this to access the first oil screen. Use pliers or a hook to pull out the screen.
    • Clean the oil screens thoroughly using contact cleaner and allow them to dry.
  • Remove and Replace Oil Filters:
    • There are usually two oil filters on the 701. Remove the cover bolts with your T30 Torx (or required socket), then carefully remove the filter cover.
    • Extract the old oil filters. Note orientation for correct installation.
    • Install the new filters from your kit. Lightly oil the new filter O-rings before installing.
  • Install Cleaned Oil Screens and Replace Plugs:
    • Reinstall the cleaned oil screens, ensuring they seat correctly.
    • Replace the drain plugs with new crush washers/sealing rings to prevent leaks.
    • Tighten all bolts to factory torque specs. Refer to your service manual for precise values.
  • Add Fresh Oil:
    • Use a funnel to add 1.5 liters of Motorex 10W/50 oil into the filler opening.
    • Replace the oil cap, start the motorcycle, and let it idle for 1–2 minutes, then shut it off.
    • Wait a few minutes, check the oil level through the sight glass. Add oil as needed (total capacity –1.7 liters including filters, but always verify via sight glass).
  • Final Checks:
    • Inspect around the drain plugs and filter cover for leaks.
    • Reinstall the engine guard/skid plate.
    • Dispose of old oil and filter responsibly.
    • Log the date and mileage of your oil change for maintenance records.

Specific Model Call-outs for 2021 Husqvarna 701 Supermoto

  • Oil changes are recommended at the first 620 miles (1,000 km) and every 6,200 miles (10,000 km) thereafter, or more frequently under race or severe conditions.
  • Always use Motorex 10W/50 synthetic oil or oil meeting Husqvarna/KTM specifications to avoid warranty issues and maximize engine protection.
  • The 701 Supermoto uses KTM—s LC4 engine, nearly identical to the KTM 690, so many aftermarket kits or tutorials for that bike will also apply.
  • Ensure oil screens are cleaned, not just replaced, as debris can accumulate and restrict oil flow. The screens are reusable if not damaged.
  • When refitting components, always use new sealing rings/crush washers to prevent leaks.
  • If you have removed the skid plate, torque it back to spec to avoid vibration and loosening during rides.
  • The total oil capacity, including a filter change, is about 1.7 liters but always check the sight glass for proper fill rather than relying solely on measurement.
  • If you are unsure about any torque specs, consult your Husqvarna 701 owner—s manual or a reputable service guide for precise numbers.

Important Tips

  • Never overfill – oil level should sit mid-way in the sight glass with bike upright and engine off.
  • Proper break-in – do the first oil change promptly at the recommended mileage to ensure the longevity of your engine.
  • Dispose of oil and filters at designated recycling facilities.

Following these steps ensures your 2021 Husqvarna 701 Supermoto continues to run smoothly, maintaining top-tier reliability and performance. For Husqvarna original parts and high-performance motorcycle gear, trust MotoSport.com for your next oil change or routine maintenance.
