OEM SPECIFICATION SUMMARY

According to the Royal Enfield Meteor 350 (J1D) Official Owner’s Manual Maintenance Specifications, the 2021–Present Royal Enfield Meteor 350 (Fireball / Stellar / Supernova) (chassis ME3J1D/J1D) requires 1.55 L (1.64 US qt) of SAE 15W-50 (JASO MA2, API SL or higher Semi-Synthetic) engine oil for a drain-only change and 1.7 L (1.80 US qt) with filter service (1570120 / HF511). Standard solo cold tire pressure is 220 kPa / 2.20 bar / 32 PSI front (100/90-19 57P) and 220 kPa / 2.20 bar / 32 PSI rear (140/70-17 66P), paired with 1× Bosch YR7MES spark plug(s) and a YTZ9-BS / 12V 8Ah VRLA battery.

4. Generation Cutoffs & Real-World Wrenching Gotchas

Model-Year & Chassis Generation Notes

First to debut Royal Enfield’s J-series 349cc platform in 2021, Fireball, Stellar, and Supernova trims all run 19/17 tubeless alloy wheels, whereas the retro-styled 2024+ Aurora trim switches to wire-spoke tube-type wheels.

Oil & Clutch Mechanical Engineering Note

Sharing 100% of its 349cc J-series engine internals with the Classic and Hunter 350, the Meteor 350 takes 1.70 L of SAE 15W-50 JASO MA2 oil with a 1570120 / HF511 paper element, paired with a generous 15.0 L teardrop tank for 450+ km cruising range.

Garage Wrenching Gotchas

  • Take advantage of the factory centerstand for chain maintenance and oil level checks; warm the engine briefly, shut down for 2 minutes on flat pavement, and verify oil sits mid-window.
  • With forward foot controls and a heel-and-toe rocker shifter, press smoothly with your heel rather than stomping down hard, protecting the shift detent pawl over high mileage.

5. Frequently Asked Questions (FAQ)

What is the comfortable cruising speed and real-world fuel range of the Meteor 350?

The counterbalanced 20.2 hp single is happiest humming along scenic backroads at 75–95 km/h (governed near 114 km/h), delivering roughly 420–480 km per 15.0 L tank.

How does Meteor 350 cold tire pressure differ from the Hunter 350?

Rolling on a 100/90-19 front wheel at 191 kg wet, the Meteor 350 runs 220 kPa (32 PSI) front cold—3 PSI higher than the 17-inch Hunter—with 220 kPa (32 PSI) solo / 250 kPa (36 PSI) two-up rear.

Should valve clearances be checked at the 500 km break-in service on a Meteor 350?

Yes—initial valve-seat bedding happens primarily in the first 500 km; verifying the cold screw-tappet clearances (0.08 mm intake / 0.18 mm exhaust) alongside the first oil/filter swap keeps idle rock-steady.
