Maintaining optimal engine temperature is vital, especially for the high-performance Beta 520 RS SM. Regular coolant changes are essential for longevity and performance. Here’s how to change the coolant on your specific model—plus a few unique things every owner of a 2013 Beta 520 RS SM should keep in mind.

Preparation – Gather Your Supplies

• Fresh motorcycle-specific coolant (pre-mixed or suitable for aluminum engines)
• Drain pan
• Socket or wrench for drain bolt
• Phillips screwdriver for shroud removal (if needed)
• Funnel
• Distilled water (for flushing, if desired)
• Clean shop rags
• Safety gloves & eye protection

Step 1: Cool Down and Access

• Ensure the engine is completely cool. Hot coolant can cause severe burns.
• Set the bike on a stable stand.
• Remove necessary body panels or radiator shrouds to access the radiator cap and drain bolt.

Step 2: Drain the Old Coolant

• Place your drain pan beneath the water pump or lowest point of the cooling system.
• Slowly remove the radiator cap to relieve pressure.
• Locate and remove the drain bolt (usually on the water pump cover). Allow all coolant to drain out.
• Optionally, gently tip or rock the bike to help drain remaining coolant from hoses and engine passages.

Step 3: Optional – Flush the System

• For a thorough flush, reinstall the drain bolt and fill the radiator with distilled water. Reinstall cap, run the engine briefly, shut down, and drain again. Repeat until water runs clear.
• This is a smart step if the old coolant was excessively dirty, or if it’s your first time servicing a pre-owned machine.

Step 4: Refill with Fresh Coolant

• Install and gently tighten the drain bolt (do not overtighten; the bolts are small and can strip easily).
• Place a funnel in the radiator fill neck.
• Slowly pour new coolant in until it reaches the base of the filler neck. Go slow and pause if you hear gurgling to allow air to escape.
• Squeeze the coolant hoses and gently rock the bike from side to side to release any trapped air bubbles.

Step 5: Burp the System – Vital for the Beta 520

• Leave the radiator cap off and start the engine. Let it idle for several minutes to circulate coolant and let remaining air bubbles rise to the top.
• Top off coolant as needed. Once level stabilizes, reinstall the radiator cap securely.
• Check and fill the overflow reservoir to the upper line.

Step 6: Final Checks

• Start the engine and let it warm up to normal operating temperature. Ensure the radiator fan cycles on (if equipped) and the temperature stays steady.
• Shut down, let the bike cool, then recheck coolant levels in both the radiator and overflow tank. Top off if required.

Key Model Notes – 2013 Beta 520 RS SM

• This Beta model features a powerful, large displacement single-cylinder engine that runs hot and works its cooling system hard, especially in tight, low-speed, or supermoto use. Never neglect routine coolant changes to prevent overheating and potential engine damage.
• Beta recommends using coolant formulated specifically for motorcycles, suitable for aluminum components, and following the capacity as listed in your manual. Overfilling can cause overflow during operation.
• If using premixed coolant, ensure it is rated for your Beta. Some coolants are not compatible with certain seals or metals found in European off-road motorcycles.
• Always check for leaks after the procedure and inspect your hoses for cracking or softness. Older hoses might need replacement—MotoSport carries OEM and upgrade parts for your ride.

Environmental Responsibility

• Always dispose of old coolant at an authorized recycling center. Do not pour it down drains or onto the ground.

By changing your coolant regularly and using the right products, your Beta 520 RS SM will continue to deliver championship performance on street or trail. If you need replacement parts, maintenance accessories, or coolants formulated for your ride, MotoSport has you covered.
