Regular coolant maintenance is vital to keep your 2017 Beta 250 RR Race dirt bike running cool through punishing rides. Unlike generic instructions, this proprietary MotoSport.com guide explains the model’s distinctive features, special tips, and crucial points every 250 RR Race owner must know for a professional-level coolant change.

Why Coolant Maintenance Matters

Beta’s 250 RR Race relies on forced liquid circulation by pump for engine cooling, making the system durability and performance directly related to clean, quality coolant and an air-free circuit.¹

What You Need

• Pre-mixed, motorcycle-specific coolant (Do not use plain water)
• Basic hand tools (socket wrench, screwdriver, pliers)
• Drain pan
• Rags
• Funnel
• Optional: new radiator cap, hose clamps if existing are worn

Key Model Note

The 2017 Beta 250 RR Race uses a twin-radiator layout with a centrally placed cap on the right side. Bleeder screws for purging air, common on much older Betas, are absent–air must be purged through fill and running procedure, so do not overfill the radiator and carefully follow the venting process.

Step-by-Step Coolant Change Instructions

1. Let the bike cool.
   Ensure your Beta is completely cool–never work on a hot system to avoid burns.
2. Remove the radiator cap.
   Unscrew the cap found on the top-right radiator. This releases any pressure.
3. Locate and remove the drain bolt.
   Find the coolant drain bolt on the water pump cover (lower right side of the engine). Place your drain pan under it, then unscrew to let old coolant flow out.
4. Inspect and flush (if desired).
   For a thorough flush, briefly refill the system with distilled water, reinstall the drain bolt, run the engine for 10–20 seconds, cool, and drain again.
5. Replace drain bolt and fill with coolant.
   Tighten the bolt securely. Use a funnel to add new pre-mixed coolant slowly into the radiator until it sits just above the internal fins–do not overfill.
6. Purge trapped air.
   With the cap off, lean the bike side to side gently to shift air pockets away from the radiator neck. Top off as the level drops. Continue until it stabilizes at the fins.
7. Start the engine briefly.
   Replace the radiator cap fully. Idle the engine 1–2 minutes, then shut off and let cool. Open the cap again and check the coolant–top up if needed.
8. Check the radiator and overflow bottle.
   Confirm the level in both locations is correct (overflow bottle between ‘min’ and ‘max’). Inspect for leaks around hoses, the drain bolt, and the radiator cap.

Additional Beta 250 RR Race Tips

• Coolant capacity is approximately 1–1.3 liters. Don’t overfill—excess may be expelled when hot.
• Watch for persistent level drops: Repeated coolant loss is a red flag for trapped air or a deeper issue elsewhere in the system.
• Check the radiator cap seal on each change–replace if the rubber is damaged or the cap fails to hold pressure.
• Annual replacement: Beta recommends renewing coolant at least once per year, or sooner if riding in muddy, sandy, or high-temp conditions.

Finish the Job Like a Pro

For a ride that stays cool under pressure, a properly serviced cooling system is essential. Keeping your 2017 Beta 250 RR Race at peak temperature performance ensures maximum horsepower and reliability–nothing ruins a ride faster than an overheating engine or a hidden leak. Always select OEM or premium quality coolant and check cooling components for wear when servicing.
