According to the Yamaha YZF-R1 / R1M (RN65) Official Owner’s Manual Maintenance Specifications, the 2020–Present Yamaha YZF-R1 / R1M (RN65 CP4) (chassis RN65/B3L) requires 3.9 L (4.12 US qt) of SAE 10W-40 (JASO MA2, API SG or higher Full Synthetic) engine oil for a drain-only change and 4.1 L (4.33 US qt) with filter service (5GH-13440-80 / 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 (190/55ZR17 M/C (75W)), paired with 4× NGK LMAR9E-J spark plug(s) and a YTZ7S battery.
Drain only: 3.9 L (4.12 US qt)
R 290 kPa (2.90 bar)
Est. Range: ~252 km (157 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Updated in 2020 (RN65) with cableless APSG ride-by-wire, revised finger-follower cylinder head, and Engine Brake Management (plus carbon winglets and Brembo Stylema calipers in 2025); note standard R1 wears a 190/55ZR17 rear while R1M mounts a 200/55ZR17.
Oil & Clutch Mechanical Engineering Note
Because the CP4 engine feeds a large lower oil cooler and magnesium sump, oil-and-filter changes take 4.10 L (3.90 L without filter)—meaning a single 4-liter jug comes up 100 ml short! Stock five 1-liter bottles of full-synthetic 10W-40 or 15W-50 JASO MA2.
Garage Wrenching Gotchas
- Yamaha fitted a tiny 6Ah YTZ7S battery to shave race weight, causing famously slow hot cranking on high-compression restarts—keep it on a smart tender whenever parked.
- Cast magnesium wheels and magnesium engine covers corrode rapidly if chipped—always use nylon rim protectors during tire swaps and torque fasteners strictly with a calibrated wrench.
5. Frequently Asked Questions (FAQ)
Does a 2020+ Yamaha YZF-R1 really take more than 4 liters of oil?
Yes—factory capacity is 3.90 L (4.12 US qt) without filter and 4.10 L (4.33 US qt) with filter replacement (4.90 L completely dry).
What spark plugs and gap are specified for the RN65 YZF-R1?
It uses four dual-ground-electrode NGK LMAR9E-J plugs gapped tighter than most streetbikes at 0.6–0.7 mm (0.024–0.028 in).
What is the tire size difference between the standard R1 and R1M?
Standard R1 wears a 190/55ZR17 rear while the R1M steps up to a 200/55ZR17; both run 250 kPa (36 PSI) front and 290 kPa (42 PSI) rear cold on public roads.
