One of the most important aspects of maintenance is knowing the engine oil capacity and changing the oil regularly. So, how much oil does an SSR 125 take?
SSR 125 Engine Oil Capacity
The SSR 125 dirt bike engine oil capacity is about 900ml to 1 liter (approximately 0.95 quarts) of 10W-40 4-stroke motorcycle oil, and it should be changed every 10 hours of riding or after a few rides to ensure proper lubrication, prevent overheating, and extend engine life.
This amount may vary slightly depending on the model year, condition of the engine, and whether you are doing a complete oil change with filter replacement.

While oil capacity is important, choosing the right oil type is equally critical. The SSR 125, being a small four-stroke dirt bike, performs best with 10W-40 motorcycle oil designed for wet clutch systems. Some riders also use 15W-40 or 20W-50 depending on the climate, but 10W-40 remains the most common and manufacturer-recommended option.
Always avoid automotive oils with friction modifiers, as they can damage the bike’s clutch and transmission.

Why Engine Oil Capacity Matters
Engine oil lubricates the moving parts of the motor, reduces friction, prevents overheating, and extends the engine’s lifespan. If you put too little oil, the engine components may not get enough lubrication, leading to overheating and wear. On the other hand, too much oil can cause foaming, increased pressure, and oil leaks. That’s why knowing the correct SSR 125 oil capacity is essential.
How to Change Oil in an SSR 125
Changing the oil in your SSR 125 is a simple task that most owners can do at home with basic tools. Here’s a step-by-step guide:
1. Warm Up the Engine
Start the bike and let it run for 3–5 minutes. This warms up the oil, making it thinner and easier to drain.
2. Place the Bike on a Stand
Secure your SSR 125 on a flat surface or use a dirt bike stand to keep it upright.
3. Locate the Drain Bolt
Find the oil drain bolt underneath the engine. Position an oil pan below it.
4. Drain the Oil
Use a socket wrench to remove the bolt and let the old oil completely drain out. Be careful—the oil may be hot.
5. Replace the Drain Bolt
Once drained, reinstall the bolt and tighten it securely, but don’t overtighten to avoid stripping the threads.
6. Add New Oil
Remove the oil filler cap on the side of the engine and pour in about 900ml–1L of fresh 10W-40 oil. Use a funnel to avoid spills.
7. Check Oil Level
Use the dipstick or oil level inspection window (depending on the model) to ensure the oil is at the proper level. Add more if necessary, but don’t exceed the recommended capacity.
8. Start the Engine & Recheck
Start the bike and let it idle for a minute. Turn it off, wait a few minutes, and check the oil level again. Top up if needed.

How Often Should You Change Oil?
For the SSR 125, it is recommended to change the oil every 10 hours of riding or after every few rides, especially if you are riding aggressively or in dusty conditions. Some riders prefer changing oil after every two to three rides to keep the engine in top condition. Since the engine only holds around a liter of oil, frequent changes are inexpensive and greatly extend engine life.
Common Oil-Related Problems in SSR 125
If the correct oil capacity and type are not used, you may face problems such as:
- Hard shifting – caused by the wrong oil type or low oil level.
- Clutch slipping – often due to automotive oil with friction modifiers.
- Overheating – results from insufficient oil or poor-quality oil.
- Oil leaks – overfilling the oil can cause excess pressure and leaks.
Sticking to the correct capacity and recommended oil type prevents these issues.
