Step-by-Step Instructions
Step 1: Warm the Engine
Start the XL750 Transalp and let it idle for 3-5 minutes to warm the oil. The new 755cc parallel-twin engine warms up quickly. Warm oil drains more completely and carries suspended contaminants out of the engine better. Park the bike on a level surface. Always perform the oil change with the bike upright, not on the side stand, to ensure complete drainage and accurate oil level measurement.
Step 2: Position the Bike
The XL750 Transalp does not come with a factory center stand. Place the bike on a rear paddock stand or have a helper hold it perfectly upright. The bike must be vertical for an accurate oil level check with the dipstick. Even a slight lean will affect the dipstick reading on this engine.
Step 3: Remove the Oil Fill Cap/Dipstick
The oil fill cap with integrated dipstick is located on the top-right side of the engine crankcase, visible from the right side of the motorcycle. Unscrew and remove the oil fill cap. This allows air into the oil system for complete drainage.
Step 4: Position the Drain Pan
Place a minimum 4-quart oil drain pan beneath the drain plug. The drain plug is on the bottom of the engine crankcase, easily accessible from underneath. The 755cc engine holds approximately 3.1 liters with filter — a 4-quart pan is adequate.
Step 5: Remove the Drain Plug
Using a 12mm hex socket, loosen the drain plug counterclockwise. Remove the final turns by hand — be ready for oil to flow immediately.
Warning: Oil may be warm. Wear gloves and eye protection.
Step 6: Drain the Oil Fully
Allow all oil to drain completely — approximately 10-15 minutes. Inspect the drained oil for unusual metallic debris. A small amount of fine dark particles is normal, but visible metallic flakes or chunks should be reviewed by a Honda service center.
Step 7: Replace the Drain Plug Sealing Washer
Remove the old aluminum sealing washer from the drain plug. Replace it with a new Honda 94109-12000 sealing washer or equivalent. Do NOT reuse the old washer — these aluminum crush washers deform during installation and will leak if reused.
Step 8: Reinstall the Drain Plug
Clean the drain plug threads and its seating area on the crankcase. Install with the new washer and hand-tighten. Using your torque wrench, tighten to 30 Nm (22 ft-lbs).
Do NOT over-torque. The XL750 crankcase is aluminum. Over-torquing strips the threads and requires expensive repair.
Step 9: Remove the Old Oil Filter
Locate the spin-on oil filter on the front-right side of the engine, just behind the front cylinder header pipe. The XL750 Transalp offers good filter access — no fairing removal needed. Position a rag or small catch pan below the filter to catch drips. Use a spin-on filter wrench to loosen, then unscrew by hand. Tip the filter opening downward as you remove it. Verify the old rubber gasket came off with the filter.
Step 10: Prepare and Install the New Filter
Before installing: 1. Apply a thin film of clean 10W-30 motorcycle oil to the rubber gasket on the new filter 2. Inspect the filter mounting surface on the engine to confirm the old gasket was fully removed 3. Wipe clean the filter mounting face on the engine block 4. Do NOT pre-fill the filter — the XL750 filter mounting angle means pre-filled oil would drip during installation
Screw the new filter on by hand. When the gasket contacts the mounting surface, tighten an additional 3/4 turn by hand.
Hand-tighten only. No filter wrench for installation. Over-tightening makes future removal very difficult and risks damaging the filter housing.
Step 11: Add New Oil
Using a funnel, pour approximately 2.9 quarts (2.7 liters) of SAE 10W-30 motorcycle oil into the oil fill port. This is the initial fill amount without the filter having been removed — if you did also change the filter, add approximately 3.3 quarts (3.1 liters). Start with the slightly lower amount and check the dipstick.
Critical: This is a Honda engine. Use 10W-30 engine oil meeting API SG or higher AND JASO MA (for wet clutch compatibility). Pro Honda GN4 10W-30 is the OEM recommendation. Do NOT use 20W-50 Harley oil. Do NOT use automotive oils with friction modifiers.
Step 12: Verify the Oil Level
- Reinstall the oil fill cap (dipstick) and tighten it securely
- Start the engine and let it idle for 2-3 minutes — this circulates new oil through the filter and galleries
- Shut off the engine and wait 2-3 minutes for oil to return to the sump
- With the bike held upright, unscrew the dipstick and check the oil level — do NOT screw the dipstick in when checking
- The oil level should be between the upper and lower marks on the dipstick
- If below the lower mark, add oil in 1/4 cup (60ml) increments, re-seat the cap, and recheck
- Once correct, tighten the fill cap securely
Step 13: Final Checks
- Inspect around the drain plug for any oil seepage
- Inspect around the oil filter for leaks
- Wipe any spilled oil from the engine cases or frame
- Dispose of used oil and filter properly (see below)
- Record this service in your maintenance log
Tips, Warnings and Common Mistakes
Helpful Tips
- Oil specification: The XL750 Transalp requires 10W-30 engine oil meeting API SG or higher AND JASO T 903 standard MA. Pro Honda GN4 10W-30 is the OEM recommendation.
- New platform: This is a 2023+ engine — the 755cc parallel-twin is new to the Transalp nameplate and is NOT the same as the older XL600V or XL650V Transalp models. Specs are different.
- Good access: Unlike the NT1100, the XL750 offers excellent oil filter and drain plug access without bodywork removal — this is one of the easier Honda oil changes.
- Filter cross-reference: The Honda 15410-KBN-013 filter cross-references with the widely available Hiflo HF401.
- Adventure riding note: If you use the Transalp for gravel or dusty conditions, consider shortening the oil change interval to 4,000-5,000 miles.
Warnings
- NEVER use automotive oils with friction modifiers — these cause wet clutch slippage. Always verify JASO MA or MA2 on the label.
- Do NOT over-torque the drain plug — the aluminum crankcase threads are vulnerable. 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 threads.
- Do NOT confuse with older Transalp models — the XL600V/650V have different oil capacities and filter part numbers.
Common Mistakes to Avoid
| Mistake | Consequence | How to Avoid |
|---|---|---|
| Using automotive oil with friction modifiers | Wet clutch slippage and damage | Verify JASO MA or MA2 on oil label |
| Over-torquing drain plug | Stripped aluminum crankcase threads | Torque to exactly 30 Nm (22 ft-lbs) |
| Reusing aluminum sealing washer | Oil leak while riding | Always replace with new washer |
| Checking oil with dipstick screwed in | Inaccurate reading — overfilling | Seat cap on threads only, do not screw down |
| Oil change on side stand | Incomplete drainage and inaccurate level | Bike must be upright and perfectly level |
| Double-gasketing the oil filter | Major oil leak from filter base | Verify old gasket fully removed |
| Using specs from older XL600V Transalp | Wrong filter or oil capacity | Use only XL750-specific 2023+ specs |
Oil Disposal
Used motor oil is hazardous waste. Never pour it down a drain, into the trash, or on the ground.
- Pour the drained oil into a clean, sealable container (empty oil bottles work well)
- 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
- Bring the old oil filter — these stores typically recycle filters as well
- Your local municipal recycling center or household hazardous waste program also accepts used oil
- Never mix used oil with other fluids (antifreeze, brake fluid, transmission fluid) — this prevents recycling
