649cc Liquid-Cooled Inline-Four DOHC 16-Valve (Wet Assist/Slipper + Optional E-Clutch) · Source: Honda CB650R / CBR650R Official Owner’s Manual Technical Specifications
According to the Honda CB650R / CBR650R Official Owner’s Manual Technical Specifications, the 2019–Present Honda CB650R / CBR650R (E-Clutch) (chassis RH02/RH15) requires 2.3 L (2.43 US qt) of SAE 10W-30 (JASO MA, API SJ or higher) engine oil for a drain-only change and 2.6 L (2.75 US qt) with filter service (15410-MFJ-D01 / HF204). Standard solo cold tire pressure is 250 kPa / 2.50 bar / 36 PSI front (120/70ZR17 M/C (58W)) and 290 kPa / 2.90 bar / 42 PSI rear (180/55ZR17 M/C (73W)), paired with 4× NGK IMR9E-9HES spark plug(s) and a YTZ10S / FTZ10S battery.
Drain only: 2.3 L (2.43 US qt)
R 290 kPa (2.90 bar)
Est. Range: ~314 km (195 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Across 2019–2020, 2021–2023 Euro 5 (SFF-BP forks), and 2024+ E-Clutch (RH15) variants, CB650R and CBR650R share identical 2.3 L / 2.6 L oil volumes, 15410-MFJ-D01 spin-on filter, and four NGK IMR9E-9HES iridium plugs.
Oil & Clutch Mechanical Engineering Note
Even on 2024+ E-Clutch models, dual electric actuators operate the standard wet multi-plate clutch pack inside the crankcase—meaning JASO MA / MA2 friction characteristics remain mandatory.
Garage Wrenching Gotchas
- Unlike most inline-fours with a sight glass, the CB650R uses a dipstick on the right clutch cover; hold the bike upright and rest the dipstick on the threads without screwing it in.
- Replacing all four NGK IMR9E-9HES plugs requires lifting the fuel tank and removing the airbox—bundle plug replacement with air filter service.
5. Frequently Asked Questions (FAQ)
Do the Honda CB650R and CBR650R use the exact same oil and filter specs?
Yes—both share the exact 649cc inline-four engine: 2.3 L drain only, 2.6 L with spin-on filter, and 250 kPa (36 PSI) front / 290 kPa (42 PSI) rear cold tire pressures.
Does the CB650R E-Clutch require special transmission fluid?
No separate fluid is used; E-Clutch models take the exact same SAE 10W-30 JASO MA engine oil (2.6 L with filter).
What is the cold tire pressure for the Honda CB650R?
Factory cold tire pressures are 250 kPa (36 PSI) front and 290 kPa (42 PSI) rear.
