Owning a 2013 Beta 520 RS SM means maintaining dual oil systemsengine and transmissionunique among dirt bikes. Routine oil changes will extend performance, longevity, and help avoid technical issues specific to this model.

Required Tools & Supplies

  • 8mm and 13mm sockets
  • Oil drain pan
  • Measuring cup (accurate to 10cc)
  • Funnel
  • Replacement crush washers (recommended)
  • Fresh engine oil (850cc) – full-synthetic preferred
  • Fresh transmission/gear oil (1000cc) – per Beta specs

Step-by-Step Guide

  1. Warm up the engine for 2–3 minutes to ensure oil flows freely and any contaminants are suspended.
  2. Remove the skid plate for better access to the drain bolts.
  3. Locate drain bolts for both engine and transmission oil. The engine drain plug is typically beneath the crankcase. The transmission side plug is separate—check your manual for precise location.
  4. Place your pan and remove the drain bolts. Give the oil several minutes to fully drain from both sides.
  5. Inspect and, if necessary, replace crush washers for each bolt. Re-install and torque bolts back to factory spec (do not over-torque).
  6. Refill engine oil: Carefully measure 850cc and pour into the engine fill. Do not rely on the sight glass exclusively; start by measuring the recommended amount first. After running the engine for a couple of minutes, check the sight glass window. Oil level should be in the middle of the window, within the red circle. If low, add a little more, but never overfill–too much oil can cause engine issues–but always verify by accurate measurement first.
  7. Refill transmission oil: Use a measuring cup to pour exactly 1000cc of gear oil into the transmission fill. Ignore the check plug method described in some manuals, as it underfills the case; always provide the full volume per Beta specs for best longevity. There is no dipstick for the transmission—precise volume is the only reliable method.
  8. Reinstall skid plate and clean any residual oil with a rag.
  9. Start your Beta 520 RS SM and let it run for 2–3 minutes. Verify there are no leaks at drain bolts or fill points. Once warmed up, check the engine sight glass again for final verification.

Model-Specific Tips & Notes

  • The Beta 520 RS SM features separate lubrication for engine and gearbox—always use correct oil grades and volumes for each compartment to prevent premature wear.
  • Do not use check plugs or underfill based on manual illustrations. Model owners report that some Beta documentation underestimates the volume needed, which can result in insufficient lubrication.
  • After every oil change, pay close attention to sight glass readings only after the engine is warmed up—cold readings can be inaccurate.
  • If you frequently ride in dusty, muddy, or extreme conditions, consider shortening oil change intervals for optimal protection.
  • Use fresh crush washers at each oil change to avoid leaks and maintain proper seal integrity.

Conclusion

Maintaining your 2013 Beta 520 RS SM is straightforward but requires attention to detail. Accurate measurement, correct oil specification, and regular changes are vital. These steps ensure your supermoto runs at peak performance—both on street and off-road.
