According to the Honda CRF300L / CRF300LR Rally (ND16) Official Owner’s Manual Specifications, the 2021–Present Honda CRF300L / CRF300 Rally (ND16) (chassis ND16) requires 1.4 L (1.48 US qt) of SAE 10W-30 (JASO MA, API SJ or higher) engine oil for a drain-only change and 1.5 L (1.59 US qt) with filter service (15410-KYJ-902 / HF103). Standard solo cold tire pressure is 150 kPa / 1.50 bar / 22 PSI front (80/100-21 M/C 51P) and 150 kPa / 1.50 bar / 22 PSI rear (120/80-18 M/C 62P), paired with 1× NGK SIMR8A9 spark plug(s) and a YTZ8V battery.
Drain only: 1.4 L (1.48 US qt)
R 150 kPa (1.50 bar)
Est. Range: ~242 km (150 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Replacing the CRF250L in 2021, the ND16 CRF300L gained a 286cc stroke and slipper clutch. Standard CRF300L carries a 7.8 L tank (142 kg), while the CRF300 Rally carries a 12.8 L tank (153 kg)—both share identical oil and plug specs.
Oil & Clutch Mechanical Engineering Note
Factory cold tire pressure on the CRF300L is just 150 kPa (22 PSI) front and 150 kPa (22 PSI) rear (175 kPa / 25 PSI rear loaded)—never inflate dual-sport 21/18 tube tires to street-bike 36 PSI.
Garage Wrenching Gotchas
- CRITICAL: Install the internal paper oil filter (HF103) with the rubber gasket facing OUTWARD (
OUT-SIDE) and the coil spring seated behind it—reversing the filter starves the top end of oil! - Don’t panic at the 880 mm static seat height—plush trail suspension sags 50–70 mm as soon as you sit down.
5. Frequently Asked Questions (FAQ)
Which way does the oil filter face on a Honda CRF300L?
Place the spring into the crankcase first, then insert the filter with the rubber seal (OUT-SIDE) facing toward the outer cover. Total refill with filter is 1.5 L (1.6 US qt).
What is the factory cold tire pressure for the Honda CRF300L?
Cold inflation is 150 kPa (22 PSI) front and 150 kPa (22 PSI) rear solo, or 175 kPa (25 PSI) rear under maximum load.
What OEM spark plug fits the Honda CRF300L?
Honda specifies the iridium NGK SIMR8A9 spark plug, replaced every 24,000 km (16,000 mi).
