Complete Tool List

Step by Step Instructions

Step 1: Warm the Engine

Start your V-Strom 1050 and let it idle for 5 to 10 minutes to warm the oil. Warm oil flows more completely and carries suspended contaminants out with it. Do NOT perform an oil change on a completely cold engine. After warming, turn off the engine and let the bike sit for 2 minutes so oil drains back into the sump.

Tip: If the bike has been sitting cold for a while, a brief 1000-meter ride will warm the oil more evenly than idling alone.

Step 2: Position the Bike on Level Ground

Place the motorcycle on a level surface using a center stand, paddock stand, or axle stand. The V-Strom 1050 uses a sight glass for oil level checking — the bike must be perfectly upright and level for an accurate reading. Do not use a side stand for any part of this procedure when checking oil level.

Step 3: Remove the Oil Fill Cap

Locate the oil filler cap on top of the engine (right side, near the front of the cylinder heads). Remove it to allow air to enter the crankcase, which ensures the oil drains freely and completely.

Step 4: Position the Drain Pan

Slide your oil drain pan beneath the engine, centered under the drain plug area. The V-Strom 1050 is a wet sump design — all oil resides in the crankcase, not in a separate tank. Make sure the pan has at least 5-liter capacity.

Step 5: Remove the Drain Plug

Using a 12 mm hex socket, loosen the drain plug on the bottom of the crankcase. Turn counterclockwise. Finish removing the last few threads by hand, being prepared for hot oil to flow immediately.

Warning: Oil may be hot enough to cause burns. Wear nitrile gloves and safety glasses.

Step 6: Drain the Oil Completely

Allow all oil to drain fully. This typically takes 10 to 15 minutes. While draining, inspect the drain plug for metal shavings, burrs, or damage. A small amount of fine metallic particles is normal; large chunks indicate a serious internal issue.

Step 7: Remove the Old Oil Filter

The oil filter is located on the right side of the engine, near the bottom — fairly accessible. Position the drain pan to catch any residual oil from the filter housing. Loosen the filter using a cap-style filter wrench or strap wrench, then spin it off by hand. Keep the drain pan beneath the filter mounting point to catch drips.

Tip: If the filter is stubbornly stuck, a rubber strap wrench works well without damaging the filter body. Avoid puncture-style removal tools if you plan to recycle the filter.

Step 8: Remove and Inspect the Old Filter Gasket

Check the filter mounting surface on the engine to confirm the old rubber gasket came off with the old filter. If the gasket has separated and stuck to the mounting surface, carefully peel it off with a plastic scraper or your fingernail.

Warning: Never install a second gasket on a fresh filter. "Double-gasketing" causes massive oil leaks and potential engine damage.

Step 9: Install the Drain Plug with New Washer

Remove the old crush washer from the drain plug and replace it with a new copper or aluminum crush washer. Clean the drain plug threads with a rag. Install the drain plug by hand, then use your torque wrench to tighten to 23 Nm.

Important: Do not over-torque. Stripping the aluminum crankcase threads is an expensive repair. Always use a torque wrench — never guess.

Step 10: Prepare and Install the New Oil Filter

Dip your finger in clean new oil and coat the rubber gasket on the new filter with a thin film of oil. This ensures a proper seal and makes future removal easier. Screw the new filter onto the engine by hand. When the rubber gasket makes contact with the mounting surface, tighten the filter an additional three-quarter (3/4) turn by hand.

Important: Do not use a wrench or filter tool to tighten the new filter. Hand-tight only. Over-tightening will damage the gasket and cause leaks.

Step 11: Add New Oil

Using a funnel, slowly pour 2.7 liters of 10W-40 JASO MA2-certified motorcycle oil into the filler port. Do not dump the entire capacity at once — you will check the level and add more in the next step.

Tip: Good oil choices include Suzuki ECSTAR S4 SAE 10W-40, Motul 7100 10W-40, Castrol POWER1 4T 10W-40, or Mobil 1 Racing 4T 10W-40. Always verify the JASO MA2 label for wet clutch compatibility.

Step 12: Circulate Oil and Check Level

1. Install the oil filler cap securely (do not overtighten)
2. Start the engine and let it idle for 2 to 3 minutes to circulate new oil through the filter and crankcase
3. Monitor the Oil Level Warning light on the dash — it should extinguish within a few seconds of starting. If it stays on, shut off the engine immediately and check oil level
4. Turn off the engine and wait 2 minutes for oil to settle back to the sump
5. Visually check the oil sight glass on the right side of the crankcase
6. Add oil in small increments (approximately 100 ml at a time) if the level is below the upper mark
7. Final oil level should be between the Upper (L1) and Lower (L2) marks on the sight glass

Critical: The V-Strom 1050 does not use a dipstick — check only the sight glass. The bike must be upright and level during this check.

Step 13: Final Inspection

• Check for leaks around the drain plug
• Check for leaks around the oil filter gasket
• Verify the oil filler cap is securely installed
• Confirm no oil drips on the ground beneath the bike
• Reset the Oil Level Warning system/service reminder if applicable
• Wipe down any spilled oil from the engine and frame

Step 14: Record the Service

Note the date, mileage, oil brand/viscosity, and filter used in your maintenance log or the Suzuki service booklet. This helps track service intervals and supports warranty claims.

Tips, Warnings & Common Mistakes

Helpful Tips

• Suzuki ECSTAR S4 SAE 10W-40 is the OEM-recommended oil and an excellent choice
• Good alternatives: Motul 7100 10W-40, Castrol POWER1 4T 10W-40, Mobil 1 Racing 4T 10W-40
• For high-temperature touring or sustained high-speed riding, 10W-50 is an acceptable alternative per Suzuki
• Always verify JASO MA2 certification on any oil — this ensures wet clutch compatibility and prevents clutch slippage
• The V-Strom 1050 has the Suzuki Intelligent Ride System (S.I.R.S.) — traction control, cruise control, etc. Your oil change does not affect these systems, but keep electrical connectors dry during the service
• Keep a maintenance log with date, mileage, oil brand, and filter used
• Check oil level before every long ride, especially during break-in periods
• Keep spare crush washers and an extra oil filter in your luggage when touring

Warnings

• NEVER use automotive oils with "Energy Conserving" labels or friction modifiers. These cause wet clutch slippage and transmission damage. Always verify JASO MA2 certification.
• NEVER start the engine without oil in the crankcase. This causes immediate and severe engine damage.
• NEVER over-torque the drain plug. The crankcase is aluminum; stripped threads require expensive repair or crankcase replacement.
• NEVER use a non-motorcycle oil filter. Automotive filters may have incorrect bypass valve pressure or wrong thread pitch, risking engine damage.
• Wait the full 2 minutes after shutdown before checking the sight glass. Checking too soon gives a false low reading, leading to overfilling.
• DO NOT check oil level on a side stand. The sight glass reading is only accurate when the bike is level and upright.

Common Mistakes to Avoid

Oil Disposal

Used motor oil is hazardous waste and must never be poured down a drain, into the trash, or on the ground. Approximately 4 ml (1/10 of a gallon) of used oil can contaminate 3.8 million liters (1 million gallons) of water.

1. Pour the drained oil into a clean container with a tight-fitting lid — the empty oil bottles work perfectly for this
2. Take it to a certified oil recycling center. Most auto parts stores accept used oil for free: - AutoZone: Free oil and filter recycling at most locations - O'Reilly Auto Parts: Free oil and filter recycling - Advance Auto Parts: Free oil recycling at participating stores - NAPA Auto Parts: Accepts used oil at most locations (call ahead to confirm) - Many municipal recycling or household hazardous waste facilities also accept used motor oil
3. Drain the old oil filter into your pan for at least 12 hours, then place it in a sealed plastic bag before taking it for recycling
4. Never mix used oil with other automotive fluids (antifreeze, brake fluid, gasoline, coolant) — this contaminates the batch and makes recycling difficult or impossible
