4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Debuted in 2018 at an ultralight 143–144 kg wet weight with IMU-controlled ABS, then upgraded in 2022 with Showa SFF-BP USD forks, an assist/slipper clutch, and a gear indicator.
Oil & Clutch Mechanical Engineering Note
Uses internal paper element 15410-KYJ-902 (HF112) with 1.5 L of SAE 10W-30 JASO MA oil—installing the filter backward blocks oil flow and starves the DOHC cam journals!
Garage Wrenching Gotchas
- Seat the coil spring against the crankcase first and face the filter’s OUT-SIDE stamp outward toward the cover; inspect the paper cover gasket every change.
- At just 144 kg wet, factory cold tire pressures are 200 kPa (29 PSI) front and 225 kPa (33 PSI) rear—inflating to 36/42 PSI makes the light chassis skittish.
5. Frequently Asked Questions (FAQ)
What oil volume, JASO grade, and oil filter code does the Honda CB300R Neo Sports Cafe (NC55) (2018–Present) require?
Because its wet multi-plate clutch shares engine oil with the gearbox, run SAE 10W-30 (JASO MA) at 1.4 L (1.48 US qt) drain-only and 1.5 L (1.59 US qt) with filter (15410-KYJ-902 / HF112).
How do you accurately check the oil level on the CB300R Neo Sports Cafe (NC55), and what are its service intervals?
Hold the motorcycle dead-vertical on level ground 2–3 minutes after warm shutdown and verify the oil sits mid-way between the Upper and Lower marks in the crankcase sight glass—never on the sidestand. Torque the drain plug to 24 N·m with a new crush washer. Factory oil change intervals are every 12,000 km, with valve clearance inspection every 24,000 km.
What are the cold tire pressures, puncture repair type, seat height, and range of the CB300R Neo Sports Cafe (NC55)?
Fitted with 110/70R17 M/C 54H front and 150/60R17 M/C 66H rear tubeless rims (compatible with roadside plug kits), set cold tire pressures to 29 / 33 PSI (200/225 kPa) solo or 29 / 33 PSI loaded. Seat height is 799 mm (31.5 in) at 144 kg wet weight, delivering ~302 km per 10 L tank.
