Shop parts for a 2022 Beta 125 RR Race Dirt Bike.The 2022 Beta 125 RR Race is a precision two-stroke machine known for its agile handling and race-focused engineering. Regularly replacing coolant ensures optimal engine temperature and the longevity of critical powertrain parts. Below you will find a MotoSport-exclusive guide to changing the coolant on this specific Beta model – with important model-specific notes to keep your dirt bike running at peak performance.
Essential Tools & Supplies
- Fresh, motorcycle-safe coolant (check the manual for specification – Beta recommends a high-quality ethylene glycol premix)
- Drain pan
- 8mm or 10mm socket or wrench (for drain bolt and radiator shrouds)
- Protective gloves & safety glasses
- Funnel
- Clean rags
Step-by-Step Coolant Change Guide
-
Preparation
Let your engine cool to avoid burns. Place the dirt bike on a stable stand and remove side radiator shrouds if needed for easier access. -
Drain the Old Coolant
Locate the coolant drain bolt – usually at the base of the water pump cover on the right side of the engine. Place a drain pan underneath. Slowly remove the radiator cap to release pressure, then loosen and remove the drain bolt.
Allow all coolant to fully drain.
Note: Newer Beta 125 RR Race models do not have the bleeder screw present on some older Betas. Air will be purged using a cycling method rather than a bleeder. -
Flush the System (Optional)
For a thorough service, pour a bit of distilled water into the radiator and let it drain out – repeat until the fluid runs clear. Reinstall the drain bolt and torque securely. -
Refill with Fresh Coolant
Using a funnel, add coolant to the radiator until just below the filler neck. Squeeze the upper radiator hose a few times to help work out trapped air bubbles. -
Air Purge – Heat Cycle
Reinstall the radiator cap. Start the engine and let it run until it reaches full operating temperature (up to the point where the fan would cycle on, if equipped). Shut down and let the engine fully cool.
Recheck the coolant level and top off as needed. Any remaining air should be purged after one or two heat cycles.
Model-Specific Tips for the Beta 125 RR Race
- This model does not use a radiator bleeder screw – air is purged by filling and the heat cycling process.
- Do not overfill; the correct level is just above the tops of the radiator cooling fins.
- The coolant reservoir acts as an expansion tank. After a complete heat cycle, always double-check and top off the coolant to maintain the correct level.
- Beta recommends using only coolants safe for aluminum components – avoid any formulas with silicates or phosphates that can damage the system over time.
- Never dispose of old coolant in the environment. Collect and bring your used coolant to an authorized recycling facility.
Final Checks
- Inspect for leaks at the drain bolt, hoses, and radiator cap area before and after riding.
- Monitor coolant level in the days following a change – a slight drop is normal as air escapes, but persistent loss indicates a leak or trapped air pocket.
Keep your 2022 Beta 125 RR Race cooling system healthy for maximum track and trail performance. For factory-spec parts, fresh coolant, and precision tools, trust MotoSport.com as your go-to source for everything Beta.
