The 2017 Beta 300 RR Race is a high-performance two-stroke dirt bike prized for its punchy power delivery and premium suspension. Keeping your transmission oil fresh is essential for maximizing clutch life, preventing premature wear, and ensuring consistent performance, especially on race models. This MotoSport-exclusive guide walks you through the complete process, focusing on the quirks and details unique to your bike.

Tools & Supplies You'll Need

  • Fresh transmission oil (Beta recommends 80w gear oil–verify the correct spec in your owner's manual)
  • 8 mm or 13 mm wrench (verify size for the drain bolt on your exact model)
  • Drain pan
  • Rag or shop towels
  • Funnel & measuring cup
  • Torque wrench (highly recommended)

Step 1: Warm Up Your Bike

Start your Beta 300 RR Race and let it run for a few minutes. Warming the engine helps the oil flow out smoothly, carrying debris with it for a more complete change. Always ensure you're working in a well-ventilated area. Caution: The oil and engine casing will get hot!

Step 2: Access the Drain Bolt

  • Secure the bike upright and level, either on a stand or lift.
  • Remove the skid plate if fitted for easier access.
  • Locate the oil drain bolt on the bottom of the engine case.

Step 3: Drain the Old Oil

  • Position the drain pan underneath.
  • Carefully loosen and remove the drain bolt.
  • Allow all oil to completely drain. This may take several minutes especially if the engine was just shut off.
  • Inspect the drain bolt for any metal debris. Wipe it clean.

Step 4: Reinstall Drain Bolt

  • Replace the drain bolt, ideally using a torque wrench to tighten to 10 Nm (about 7.5 ft-lb) as specified for many Beta models.

Step 5: Fill with Fresh Oil

  • Remove the transmission oil fill cap on the side of the engine. Use a funnel for a clean pour.
  • The standard oil capacity for a 2017 Beta 300 RR Race is 800 cc (0.8 liters) for a routine oil change. For engine overhauls, increase to 850 cc.
  • Pour the measured oil slowly to avoid overflow. Wait a moment to let it settle, then check the level via the inspection screw.
  • If the oil is above the lower edge of the check hole, allow any excess to drain until it is level.

Step 6: Check & Reinstall Everything

  • Inspect and clean the fill cap threads and O-ring. Replace if worn.
  • Install and hand-tighten the fill cap.
  • Wipe away any oil residue. Refit the skid plate if removed.

2017 Beta 300 RR Race–Owner Notes & Tips

  • Filling: Always measure and confirm oil level through the check bolt. Overfilling can stress gaskets and reduce clutch performance.
  • Oil Choice: The 300 RR Race transmission is happiest with a dedicated 80w gear oil or premium 10w/40 motorcycle oil. Many owners prefer Bel-Ray Gear Saver or similar.
  • Maintenance Interval: For hard enduro or aggressive riding, change transmission oil every 10-15 hours for best protection.
  • Check Bolt Caution: The threads on the check screw can be delicate. Avoid over-tightening and always use the correct tool size.
  • Model-specific design: The Race Edition is built with competition in mind, featuring enhanced clutch feel and minimal slip for rapid engagement. Keeping oil clean on this model noticeably boosts shifting and protects intricate clutch components.

MotoSport Pro Tips

  • Always dispose of old oil and filters properly at a recycling center.
  • Take the time to check for leaks after your next ride, and re-torque bolts if necessary.
  • Bookmark this routine at each service interval, and consider logging oil changes in a maintenance notebook for your 300 RR Race.
