- Drain pan
- 8mm and 10mm socket or wrench
- Phillips screwdriver
- Funnel
- Clean rags
- Gloves and eye protection
Key 2018 Beta 300 RR Race Notes
- Coolant capacity is approximately 1.3 liters.
- No radiator bleeder screw is installed on the 2018 Race model—bleeding is performed using the radiator cap.
- Always change coolant with the engine completely cold.
Step-by-Step Coolant Change Procedure
- Ensure Safety
Place your bike on a stand in a well-ventilated area. Allow the engine and radiators to cool fully before starting. Wear gloves and eye protection. - Remove Seat – Side Panels
Detach the seat and left radiator shroud/panel using the appropriate bolts or quick-release systems. This grants access to the radiator cap. - Open Radiator Cap
Twist and remove the radiator cap slowly to release any pressure. - Locate – Remove Drain Bolt
On the lower right side of the engine case (water pump housing), use an 8mm or 10mm socket to remove the coolant drain bolt. Some coolant may spill quickly, so have your drain pan ready. - Drain Coolant
Allow all coolant to empty into the pan. Tilt the bike gently from side to side to encourage full drainage. - Inspect the Coolant
Examine drained coolant for contamination or debris, which may indicate further maintenance is required. - Refit Drain Bolt
Reinstall and tighten the drain bolt by hand, then torque to factory specifications. Wipe away any spills. - Refill Coolant
Insert a funnel into the radiator filler neck. Pour new coolant slowly until it reaches just above the top of the radiator fins (not all the way to the overflow). The total capacity is about 1.3 liters but add slowly and avoid overfilling. - Bleed the System
With the radiator cap off, gently rock the bike to release trapped air. Watch the coolant level drop and top off as necessary. There is no bleeder screw; instead, continue rocking and topping up until bubbling stops and coolant level stabilizes near the top of the fins.
Tip: If available, refer to your owner's manual for diagrams. - Reinstall Radiator Cap
Confirm coolant is at the correct level. Clean the cap and reinstall securely. - Reassemble Bodywork
Replace radiator shroud/panel and seat. Tighten all fasteners appropriately. - Final Checks
Start the engine and let it idle for several minutes. Monitor coolant level and inspect for leaks. After the bike cools, recheck coolant and top off as needed.
Maintenance Tips for Your 2018 Beta 300 RR Race
- Check coolant condition and level every ride.
- Avoid mixing coolant types – stick with Beta's recommended coolant formulas.
- Inspect hoses and clamps for signs of wear or leaks during coolant changes.
- The 2018 Beta 300 RR Race uses a dedicated water pump drive mechanism—routine service keeps this critical component healthy.
