Shop parts for a 2024 Beta 350 RR Dirt Bike!
Changing the oil in your 2024 Beta 350 RR is essential maintenance that keeps your high-performance four-stroke engine running strong. Unlike many other off-road bikes, the Beta 350 RR features separate engine and transmission oil compartments–each requiring regular attention and the right oil volume. This guide provides a step-by-step routine specific to this model, along with pro tips every owner should know.
What Makes Oil Changes Unique on the 2024 Beta 350 RR?
- Separate engine & transmission oil chambers: Each uses its own drain bolt and oil fill point, increasing reliability and reducing cross-contamination.
- Sight glass & check bolts: The engine oil is checked at the sight window while running; transmission oil is checked with the check bolt after the engine is turned off.
- Oil quantity precision: Overfilling or underfilling each side can lead to premature wear or performance issues.
Tools & Supplies You Will Need
- Drain pan
- 8mm & 13mm sockets or T-handles
- New engine oil filter
- New O-rings (for both drain bolts & filter cover)
- Liqui Moly 10W-50 (or Beta-approved 10W-50 full synthetic), at least 1.5 liters
Step-by-Step Oil Change Procedure
-
Warm Up the Engine
Briefly start and idle the motorcycle for 2 minutes. Warming the oil allows better drainage and brings contaminants into suspension. -
Remove Skid Plate
If your Beta 350 RR is equipped with a skid plate, remove it using the appropriate tools for easier access to drain bolts. -
Drain the Engine Oil
Place a drain pan beneath the engine. Using a 13mm socket, remove the engine oil drain bolt.
Allow all oil to drain fully. Inspect and replace the O-ring as needed–this prevents leaks. -
Drain the Transmission Oil
Move the drain pan beneath the transmission. Remove the transmission oil drain bolt and let oil drain completely.
Replace the O-ring on the bolt before reinstallation. -
Remove the Oil Filter
Remove the two 8mm filter cover bolts. Take off the cover, then the old oil filter and its cover O-ring.
Let any extra oil drain out before installing the new filter. -
Install New Oil Filter & O-rings
Place a new O-ring on the filter cover and insert the new oil filter, open end facing in toward the engine.
Tighten the filter cover bolts to 10 Nm. -
Reinstall & Torque Drain Bolts
Replace engine oil drain bolt (15 Nm torque) and transmission drain bolt (20 Nm torque), both with new O-rings. -
Fill with Correct Oil Volume
Pour 750 ml of fresh oil into each side: 750 ml for the engine, 750 ml for the transmission.
Use new O-rings on the fill caps. Tighten securely. -
Check Oil Levels
Start the engine and let it idle for 2 minutes.- For the engine: With the engine running, oil should sit in the middle of the sight glass.
- For the transmission: With the engine off, check oil at the check bolt – oil should just reach the bottom of the threads.
- Reinstall Skid Plate and check for leaks around all service points.
Special Tips for 2024 Beta 350 RR Owners
- Always replace O-rings with each oil change to ensure a perfect seal.
- Never overfill; use a graduated container for accuracy. Too much oil can pressure-seal and damage engine internals.
- Expect to drain less than the full 750 ml per side. Some residual oil always remains in the engine & transmission even after a proper drain.
- Engine oil level must be checked while running—this is unique to Beta; other brands typically require the engine to be off.
- If your bike is brand new, perform your first oil change after only 3 hours of run time to remove any manufacturing debris.
Whether riding hard enduro or fan-favorite singletrack, regular oil changes on your 2024 Beta 350 RR will keep your motor responsive and enjoyable for years. For all your oil, filters, and maintenance needs, remember to Shop parts for a 2024 Beta 350 RR Dirt Bike!
