Shop parts for a 2013 Beta 450 RS SM Dirt Bike!
Regular oil changes are essential maintenance for keeping your 2013 Beta 450 RS SM running strong, especially if you demand peak performance from your supermoto or use it off-road. This model features a unique dual-oil system – one for the engine and one for the transmission. Here is a proprietary MotoSport guide for performing a thorough oil change on your Beta.
What Makes the 2013 Beta 450 RS SM Unique?
- Separate engine and transmission oil circuits – Many dirt bikes combine engine and transmission oil, but the Beta 450 RS SM is distinct because each system uses its own oil volume and drain plug.
- Differentiated oil capacities – Both sides require precise refilling. Overfilling or underfilling can affect oil circulation and long-term durability.
- O-ring service – O-rings on both the filter cap and drain bolts need to be replaced every service for the best seal and engine protection.
Required Tools & Parts
- 13mm socket and ratchet
- 8mm socket or wrench
- Drain pan
- Replacement oil filter
- New O-rings for the filter cover and drain bolts
- Recommended 10W-50 4-stroke engine oil
- Clean rags
- Torque wrench (recommended for reinstalling bolts)
Step-by-Step Oil Change Instructions
- Warm up the engine for 2–3 minutes to get the oil flowing. Shut down and let it cool slightly for safe handling.
- Remove the skid plate by loosening the bolts (typically 8mm) beneath the engine.
- Place a drain pan underneath the engine area.
- Remove both drain bolts – You will find a drain bolt for the engine side and another for the transmission side. Both use a 13mm socket. Let both systems drain completely.
- Remove the oil filter cover (8mm bolts) and pull out the oil filter. Remove and inspect the filter cover O-ring. Replace it with a new one to ensure a good seal.
- Install a fresh oil filter, ensuring the open end faces the engine and the solid end faces the cover.
- Replace the O-rings on both drain bolts and the filler caps using the replacements from a quality oil change kit.
- Reinstall and torque the engine drain bolt to 15 Nm and the transmission drain bolt to 20 Nm. Tighten the oil filter cover to 10 Nm.
- Fill with fresh oil:
- Engine: Add exactly 750ml of 10W-50 oil.
- Transmission: Add 750ml of 10W-50 oil.
- Reinstall the filler caps (be sure the O-rings are new or in excellent condition).
- Run the engine for 2 minutes at idle, then shut off and let it sit for a moment.
- Check for leaks around the drain bolts, filter cover, and filler caps.
Owner Tips for the 2013 Beta 450 RS SM
- Do not use the oil check plug or rely on the sight glass for this model; these are known to give misleading level readings after a fresh fill. Using the correct volume is the most accurate method.
- Replace O-rings every service – This simple step prevents leaks and contamination.
- Track your oil change intervals in your maintenance log for best engine and gearbox health.
- Use only the specified oil (10W-50 full synthetic), as recommended for Beta's four-stroke engines.
Performing regular, precise oil changes the right way helps ensure years of reliable power from your Beta. If you need parts or a complete oil change kit, Shop parts for a 2013 Beta 450 RS SM Dirt Bike!
