Oil changes are essential for keeping your 2014 Beta 450 RS SM running strong. MotoSport has a proprietary, step-by-step guide for owners eager to maintain peak performance – whether you ride on the street or trail.
What Makes the 2014 Beta 450 RS SM Unique?
This model features separate engine and transmission oil circuits, which means you must change the oil in both locations during service. The recommended quantities and procedure differ from typical Japanese dual sport bikes. Owners should always use high-quality motorcycle-specific oils and new o-rings at every change for both drain bolts and oil filter caps to prevent leaks and ensure longevity.
Items You Will Need
- Liqui Moly 10W–50 or equivalent motorcycle oil
- Oil drain pan
- 13mm and 8mm sockets
- Torque wrench
- New o-rings for drain bolts and filter caps
- Replacement oil filter
- Cleaning rags
Step-by-Step Instructions
- Warm up your engine for several minutes – a warm engine drains oil better.
- Remove the skid plate using the 8mm socket.
- Locate both drain bolts: Engine and transmission drain bolts are both 13mm. The engine drain bolt is slightly larger, with a pre-screen basket – easily accessed underneath on the right side.
- Position your oil drain pan beneath the engine.
- Remove both drain bolts – first engine, then transmission. Allow oil to fully drain from both areas.
- Remove the oil filter cover (two 8mm flange bolts). Carefully extract the old oil filter and o-ring. Leaving the cover off helps with complete drainage.
- Install new o-rings on both drain bolts and the oil filter cover. Fit the new oil filter, with the open end facing into the engine. Replace the cover and tighten the bolts to 10 Nm.
- Re-install drain bolts: Torque engine drain bolt to 15 Nm, transmission drain bolt to 20 Nm.
- Refill both circuits:
- Engine side: Add 750 ml of oil
- Transmission side: Add 750 ml of oil
- Replace both oil filler cap o-rings, then install and hand-tighten the caps.
- Start the bike and let it idle for 2 minutes. Check the engine oil level through the sight glass – it should be in the middle while running.
- Check transmission oil level with the oil check bolt – oil should be up to the bottom of the threads.
- Inspect for leaks and verify levels before your next ride.
Special Notes for the 2014 Beta 450 RS SM Owner
- Always use new o-rings for every oil change. This prevents common leaks seen on models that reuse old o-rings.
- Ignore the "fill to lower sight glass" advice referenced for other years in forums – the 2014 requires exact measurements for long-term reliability and clutch performance.
- After refilling, check oil levels with the bike upright and running for engine – and off for transmission.
- If your bike sees heavy off-road use, change oil more frequently than manufacturer intervals.
Proper oil change technique preserves your 2014 Beta 450 RS SM’s performance & value. Trust MotoSport for all your maintenance and upgrade needs.
