4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
2021+ Gen 2 (RH10) and 2025+ (RH21 with cruise control) take 3.2 L drain-only and 3.4 L when replacing BOTH the spin-on engine oil filter AND the small DCT clutch paper element.
Oil & Clutch Mechanical Engineering Note
NOT A CVT SCOOTER: The X-ADV 750 runs Honda’s 6-speed Dual Clutch Transmission bathed in engine oil + 520 chain final drive. NEVER use JASO MB scooter oil! Always use SAE 10W-30 JASO MA and remember there are TWO oil filters (main spin-on HF204 + right-side DCT clutch paper filter HF117).
Garage Wrenching Gotchas
- New owners often mistake the X-ADV for a belt scooter because of its floorboards and plastic chain cover—it uses an exposed 520 O-ring chain that requires regular cleaning and lubrication!
- Tangentially laced cross-spoke rims take tubeless tires—set 250 kPa (36 PSI) front and 280 kPa (41 PSI) rear cold.
5. Frequently Asked Questions (FAQ)
Does the Honda X-ADV 750 have two separate oil filters?
Yes—one main spin-on cartridge (15410-MFJ-D01 / HF204) and one small paper DCT clutch filter (15412-MGS-D21 / HF117) on the right crankcase cover. Replacing both requires 3.4 L of SAE 10W-30 JASO MA oil.
Can I use ADV 350 scooter oil in an X-ADV 750?
Never! ADV 350 uses dry-CVT JASO MB oil, whereas X-ADV 750’s wet Dual Clutch Transmission strictly requires JASO MA oil.
What is the cold tire pressure for the Honda X-ADV 750?
Cold tire pressure is 250 kPa (36 PSI) front and 280 kPa (41 PSI) rear.
