Oil Change Guide: 2026 Honda NT1100

Quick Reference Table

Difficulty and Time Estimate

• Difficulty Level: Beginner to Intermediate (2 out of 5)
• Estimated Time: 35-45 minutes (first-timer: 50-65 min)
• Best Done: On a warm engine after a short ride, bike upright on level surface
• Special Note for NT1100: The under-tray fairings on the sport-touring design require partial removal for access to the drain plug and oil filter. This adds 10-15 minutes to the process compared to naked bikes.

Step-by-Step Instructions

Step 1: Warm the Engine

Start the NT1100 and let it idle for 3-5 minutes to warm the oil. The liquid-cooled Africa Twin–derived engine warm up relatively quickly. Warm oil drains more completely and carries suspended debris out of the engine better. Park the bike on a level surface, upright on its wheels (not on the side stand).

Step 2: Position the Bike

Ideally, place the NT1100 on a rear stand or paddock stand to keep it perfectly vertical. If you do not have one, center stand position or a helper holding the bike upright is acceptable. The bike must be level for accurate oil level measurement with the dipstick. The NT1100 center stand (if equipped) works well for this purpose.

Step 3: Remove Under-Body Fairing / Belly Pan

The NT1100 sport-touring design features lower fairings that partially or fully cover the oil drain area. Using a Phillips screwdriver and/or 8mm-10mm sockets, remove the necessary under-tray fasteners to access the drain plug and oil filter. Set all bolts and clips aside safely.

Tip: Take a photo of the fairing bolt pattern before removal to remember reassembly locations and orientation.

Step 4: Remove the Seat and Oil Fill Cap

Open the seat lock and remove the seat. Locate the oil fill cap with integrated dipstick on the right side of the engine/transmission case. Unscrew the fill cap but do not reinstall it yet — an open fill port allows air to enter for a faster, more complete drain.

Step 5: Position the Drain Pan

Place a minimum 4-quart capacity oil drain pan beneath the oil engine's drain plug. The drain plug is located on the bottom of the crankcase, near the bottom-left side of the engine case. Position carefully — with the lower fairing removed, you should have adequate clearance.

Step 6: Remove the Drain Plug

Using a 12mm hex socket and ratchet, loosen the drain plug counterclockwise. Remove the final turns by hand while applying gentle inward pressure — be ready for oil to flow immediately as the plug clears the threads.

Warning: Oil may be warm. Wear gloves and eye protection. Allow the hot oil to flow away from your hands.

Step 7: Drain the Oil Fully

Allow all oil to drain completely — approximately 10-15 minutes. While draining, inspect the oil stream for any unusual metallic debris. A small amount of fine dark particles is normal for break-in and regular operation, but visible chunks, flakes, or excessive metallic material should be reviewed by a Honda service center immediately.

Step 8: Replace the Drain Plug Sealing Washer

Remove the old aluminum crush washer from the drain plug. Replace it with a new Honda 94109-12000 aluminum sealing washer or equivalent. Do NOT reuse the old washer — these crush washers deform during installation and will not seal properly if reused.

Step 9: Reinstall the Drain Plug

Clean the drain plug threads and its sealing surface on the crankcase with a clean shop towel. Install the plug with the new washer and hand-tighten first. Then, using your torque wrench with the 12mm socket, tighten to 30 Nm (22 ft-lbs) exactly.

Warning: Do NOT over-torque. The NT1100 crankcase is aluminum alloy. Over-torquing strips the threads, requiring expensive crankcase repair or replacement.

Step 10: Remove the Old Oil Filter

Locate the spin-on oil filter on the lower-left side of the engine (forward, near the clutch cover). Position a portion of the drain pan or a small catch container beneath the filter to catch drips. Use a spin-on filter wrench to loosen, then unscrew by hand. Be careful — the filter contains retained oil that will spill freely once it breaks loose. Verify the old rubber gasket came off completely with the old filter, not stuck to the engine.

Step 11: Prepare the New Filter

Before installing the new filter: 1. Apply a thin, even film of clean 10W-30 motorcycle oil to the rubber gasket on the new filter. This ensures a proper seal and makes future removal easier. 2. Inspect the filter mounting surface on the engine to confirm the old gasket was fully removed. 3. Do NOT pre-fill the filter — the NT1100 filter mounts at an angle and pre-filling will cause oil to spill during installation.

Step 12: Install the New Oil Filter

Screw the new filter onto the filter housing by hand. When the gasket first contacts the mounting surface, tighten an additional 3/4 turn by hand.

Hand-tighten only. Do NOT use a filter wrench for installation. Over-tightening makes future removal extremely difficult and can damage the gasket.

Step 13: Add New Oil

Using a funnel, pour approximately 3.0 liters (2.8 quarts) of SAE 10W-30 motorcycle oil into the oil fill port.

Critical: This engine uses the Africa Twin platform. Always use oil meeting API SG or higher AND JASO MA or MA2 for wet clutch compatibility. Do NOT use 20W-50 or automotive oils with friction modifiers. Recommended: Pro Honda GN4 10W-30, Honda HP4 10W-30, Mobil 1 Racing 4T 10W-30, or any quality 10W-30 motorcycle oil with JASO MA/M2 verification.

Step 14: Verify the Oil Level

1. Reinstall the oil fill cap (dipstick) — place it on the filler neck and tighten securely
2. Start the engine and let it idle for 2-3 minutes. This circulates oil through the new filter
3. Shut off the engine and wait 2-3 minutes for oil to drain back to the sump
4. Remove the dipstick, wipe clean, insert it into the filler neck without screwing it in (Honda specifies checking with the cap simply seated, not threaded down), then remove and check the level
5. The oil level should be between the upper and lower marks on the dipstick
6. If below the lower mark, add oil in small increments (50-100ml), reinstall the dipstick seated (not screwed in), and recheck
7. Once at the correct level, securely tighten the fill cap back in

Critical: Honda dipstick check method is different from many other brands. The dipstick must be seated but NOT screwed in for the level reading. Checking with it screwed in will give a false low reading and lead to overfilling.

Step 15: DCT-Specific Note (DCT Models Only)

If your NT1100 has the 6-speed Dual Clutch Transmission, the DCT system uses a separate fluid reservoir (Honda DCT Fluid TL-V). This fluid is NOT changed during a standard engine oil change. Refer to your owner's manual for DCT fluid service intervals. The engine oil change in this guide applies to manual and DCT models — the engine oil circuit is identical on both.

Step 16: Final Checks

• Inspect the drain plug area for any oil seepage
• Inspect around the oil filter base for leaks
• Wipe any spilled oil from the engine cases, frame, and fairings
• Reinstall all under-body fairing bolts and clips securely
• Reinstall the seat
• Dispose of used oil and filter properly (see below)
• Record this service in your maintenance log with date, mileage, oil brand, and filter part number

Tips, Warnings and Common Mistakes

Helpful Tips

• Oil specification: The NT1100 uses 10W-30 engine oil meeting API SG or higher AND JASO T 903 standard MA or MA2 for wet clutch compatibility. Pro Honda GN4 10W-30 or HP4 10W-30 are Honda OEM choices.
• Keep a log: Record date, mileage, oil brand, and filter part number for warranty documentation and maintenance tracking.
• Buy a crush washer pack: Keep a handful of 12mm aluminum sealing washers (Honda 94109-12000) on hand so you always have a fresh one ready.
• Filter cross-reference: The Honda 15412-MJK-G01 filter uses the same thread pattern as the Africa Twin filter and cross-references directly to the Hiflo HF204, widely available at motorcycle shops and online.
• Sport-touring access: Consider removing the belly pan every time for a cleaner workspace — it takes only a few extra minutes but prevents oil from dripping onto fairing surfaces.

Warnings

• NEVER use automotive oils with friction modifiers — these cause wet clutch slippage in the NT1100. Always verify JASO MA or MA2 certification.
• Do NOT over-torque the drain plug — the aluminum crankcase threads can be damaged. Torque to exactly 30 Nm (22 ft-lbs).
• Do NOT check oil level with the dipstick screwed in — Honda specifies checking with the dipstick simply seated on the filler neck, not threaded down.
• DCT models have separate fluid systems — do NOT mix engine oil with DCT fluid. Each has its own reservoir, cap, and drain point.

Common Mistakes to Avoid

Oil Disposal

Used motor oil is hazardous waste. Never pour it down a drain, into the trash, or on the ground.

1. Pour the drained oil into a clean, sealable container (empty oil bottles work well)
2. Take it to a certified recycling center. Most major auto parts stores accept used oil at no charge: - AutoZone — free oil recycling, all locations - O'Reilly Auto Parts — free oil and filter recycling - Advance Auto Parts — free oil recycling - NAPA Auto Parts — most locations accept oil, call ahead
3. Bring the old oil filter — these stores typically recycle filters as well
4. Your local municipal recycling center or household hazardous waste program also accepts used oil
5. Never mix used oil with other fluids (antifreeze, brake fluid, transmission fluid, DCT fluid) — this prevents recycling
