Oil Change Guide: 2025 Honda Africa Twin CRF1100L

Quick Reference Table

Difficulty and Time Estimate

• Difficulty Level: Intermediate (2 out of 5) — adventure bike ergonomics, skid plate may need removal, higher ground clearance
• Estimated Time: 45-60 minutes (first-timer: 60-75 min)
• Best Done: On a warm engine, bike upright on center stand or rear stand — off-road riding conditions make this more important

Step-by-Step Instructions

Step 1: Warm the Engine

Start the Africa Twin and idle for 5-10 minutes. The 1,084cc parallel-twin is the same displacement as the Rebel 1100 but with different internals and higher performance tuning — it benefits from good warming before drainage. Park the bike on a level surface. Off-road riding kicks up dirt on the crankcase — cleaning under the bike before starting is recommended.

Step 2: Remove the Skid Plate (If Equipped)

Most Africa Twins come with a factory skid plate that must be removed to access the drain plug and oil filter. Using appropriate metric hex keys or socket drivers (typically 4mm or 5mm), remove the skid plate mounting bolts. Set aside the bolts and the plate carefully. Set the plate upside down on the ground to keep it clean.

Note: If your Africa Twin does not have a skid plate, skip this step and proceed to drain plug access.

Step 3: Position the Bike Upright

The Africa Twin must be perfectly upright for an accurate oil level check. Use the center stand if equipped (some models have it, some do not), or a rear paddock stand. Do NOT rely on the side stand for an oil change.

Step 4: Remove the Oil Fill Cap

Locate the oil fill cap/dipstick on the top of the engine (right side, underneath the fuel tank area). Remove the cap to allow air into the oiling system for complete drainage.

Step 5: Position the Drain Pan

Place a minimum 6-quart oil drain pan beneath the drain plug. The Africa Twin holds more oil than many motorcycles — ensure adequate capacity. Position the pan to account for the higher ground clearance and potentially angled bike.

Step 6: Remove the Drain Plug

Using a 12mm hex socket on an extension (a 6-inch extension helps reach past the skid plate mount area), loosen the drain plug counterclockwise. Remove the final turns by hand — be ready for oil flow.

Warning: Oil may be warm. The Africa Twin's engine runs hot during off-road use — take care.

Step 7: Drain All the Oil

Allow complete drainage — approximately 10-15 minutes. Inspect the drain plug and drained oil carefully. Off-road riding may introduce more debris into the engine sump. Fine metallic particles are normal, but any unusual material should be evaluated.

Step 8: Replace the Sealing Washer

Remove the old aluminum sealing washer from the drain plug. Replace with a new Honda 90471-PCP-000 or equivalent. Never reuse these washers — they are designed to deform once for a proper seal.

Step 9: Reinstall the Drain Plug

Clean the drain plug threads and its seating area on the crankcase. Install with the new washer, hand-tighten, then torque to 25 Nm (18 ft-lbs) using a torque wrench.

Do NOT over-torque. The aluminum crankcase requires exactly 25 Nm.

Step 10: Remove the Old Oil Filter

The Africa Twin oil filter is typically on the right side of the engine, partially behind the skid plate mount area. Position catch rags. Use a spin-on filter wrench to loosen, then unscrew by hand. Check that the old gasket came off with the filter.

Step 11: Prepare the New Oil Filter

Before installing: 1. Apply a thin film of clean 10W-30 motorcycle oil to the new filter's rubber gasket 2. Inspect the filter mounting surface on the engine — confirm the old gasket is fully removed 3. Do NOT pre-fill the filter — it is mounted on an angle and will spill during installation

Step 12: Install the New Oil Filter

Thread the new filter on by hand. When the gasket contacts the mounting surface, tighten an additional 3/4 to 1 turn by hand.

Hand-tighten only. No filter tools for installation.

Step 13: Add New Oil

Using a funnel, pour approximately 3.4 quarts (3.2 liters) into the oil fill port (for manual transmission models). If your Africa Twin is equipped with the Honda DCT (Dual-Clutch Transmission), it holds slightly more — use approximately 3.6 quarts as a starting point. Use Pro Honda HP4 or GN4 10W-30, or any API SG+ rated oil with JASO MA certification.

Critical: The Africa Twin shares the same 1,084cc parallel-twin engine platform as the Rebel 1100, but with different tuning and higher performance. Use 10W-30 motorcycle oil — not 20W-50, and never automotive oil.

Step 14: Verify the Oil Level

1. Reinstall the oil fill cap and tighten
2. Start the engine and idle for 2-3 minutes
3. Shut off and wait 3-5 minutes (longer wait recommended for adventure bikes that may have been ridden on uneven terrain)
4. Remove the fill cap, wipe the dipstick clean
5. Insert the dipstick WITHOUT screwing it in, then remove and check the level
6. Oil should be between the upper and lower level marks
7. Add oil in small amounts if needed, rechecking between additions
8. Tighten the fill cap when correct

Step 15: Reinstall the Skid Plate and Final Checks

1. Reinstall the skid plate with all mounting bolts, torqued to factory specifications
2. Check for leaks at the drain plug
3. Check for leaks at the oil filter
4. Wipe any spilled oil from engine, frame, and skid plate
5. Dispose of used oil and filter properly (see below)
6. Record this service in your adventure motorcycle maintenance log

Tips, Warnings and Common Mistakes

Helpful Tips

• Oil recommendation: Honda Pro HP4 10W-30 semi-synthetic is the top OEM choice for the Africa Twin, especially given its high-performance engine and off-road capability. Pro Honda GN4 10W-30 is also excellent.
• Adventure riding considerations: After extended off-road use or dusty trail riding, consider changing the oil more frequently than the 8,000-mile interval. Dust and fine dirt ingress can accelerate oil degradation.
• DCT models: If your Africa Twin has the Dual-Clutch Transmission, note that it holds slightly more oil. Use the DCT-specific capacity from your owner's manual as a reference.
• Carry spares: For adventure touring, carry a spare drain plug washer and oil filter in your luggage. You may be far from a Honda dealer.

Warnings

• NEVER use automotive oils with friction modifiers — the Africa Twin's wet clutch requires JASO MA/MA2 oil.
• Do NOT skip the oil level check — running low on oil during an adventure ride, especially in hot, dusty conditions, can cause severe engine damage.
• Do NOT over-torque the drain plug — the aluminum crankcase on the Africa Twin can not be easily repaired.

Common Mistakes to Avoid

Oil Disposal

Never pour used motor oil down a drain, into trash, or on the ground.

1. Transfer drained oil to a sealed container
2. Drop off at: - AutoZone — free recycling - O'Reilly Auto Parts — free oil and filter recycling - Advance Auto Parts — free oil recycling - NAPA Auto Parts — check local availability
3. Include old oil filter
4. Municipal recycling or hazardous waste facilities also accept oil
5. Never mix oil with other automotive fluids (antifreeze, brake fluid, etc.)
