109cc Air-Cooled Single-Cylinder SOHC Long-Stroke (Wet Centrifugal 4-Speed Rotary) · Source: Honda Super Cub 110 (JA59) Official Owner’s Manual Maintenance Specifications
According to the Honda Super Cub 110 (JA59) Official Owner’s Manual Maintenance Specifications, the 2022–Present Honda Super Cub 110 (JA59) (chassis JA59) requires 0.8 L (0.85 US qt) of SAE 10W-30 (JASO MA, API SG or higher) engine oil for a drain-only change and 0.85 L (0.90 US qt) with filter service (15412-MGS-D21 / HF117). Standard solo cold tire pressure is 200 kPa / 2.00 bar / 29 PSI front (70/90-17 M/C 38P) and 225 kPa / 2.25 bar / 33 PSI rear (80/90-17 M/C 50P), paired with 1× NGK CPR8EA-9S spark plug(s) and a YTZ4V / YTZ5S battery.
Drain only: 0.8 L (0.85 US qt)
R 225 kPa (2.25 bar)
Est. Range: ~267 km (166 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
The 2022+ JA59 generation introduced cast tubeless wheels, front disc ABS, and a replaceable paper oil filter element (15412-MGS-D21). Earlier 2018–2021 JA44 spoke-wheel models had no cartridge filter.
Oil & Clutch Mechanical Engineering Note
Even though there is no hand clutch lever, the Super Cub 110 uses a wet automatic centrifugal clutch and 4-speed gearbox sharing engine oil. Always use JASO MA / MA2 oil—never JASO MB scooter oil.
Garage Wrenching Gotchas
- Do not neglect the drive chain just because it is hidden inside the full metal chaincase; pop open the rubber inspection plug every 1,000 km to check slack and lube.
- Because the air-cooled sump holds only 0.80 L of oil, summer wide-open-throttle commuting degrades oil quickly—refresh every 2,000–2,500 km under heavy use.
5. Frequently Asked Questions (FAQ)
Can I put PCX scooter oil (JASO MB) into a Honda Super Cub 110?
No. The Super Cub 110 uses an oil-bathed wet centrifugal clutch; JASO MB scooter oil causes clutch slippage under load. Always use JASO MA or MA2 oil.
What is the oil capacity of the 2022+ Super Cub 110 (JA59)?
Drain-only refill is 0.80 L (0.85 US qt), and oil plus paper filter element replacement is 0.85 L (0.90 US qt).
Does the JA59 Super Cub 110 have tubeless tires?
Yes—starting with the 2022 JA59 model, cast alloy wheels with factory tubeless tires (70/90-17 front, 80/90-17 rear) come standard.
