Royal Enfield Classic 350 Maintenance Schedule and Service Info
This is the maintenance schedule and associated service intervals for the Royal Enfield Classic 350. It applies to all models built on the J-platform with the 349cc air/oil-cooled single-cylinder engine, introduced in 2022. This engine is also used in the Meteor 350 and Hunter 350, and features a SOHC two-valve layout with electronic fuel injection and a counterbalanced crankshaft.
The J-platform replaced the older UCE-based Classic 350, and the two generations do not share components. The new engine delivers smoother performance and simplified maintenance, with the same interval recommendations across all J-platform models. Here are all of the motorcycles that share the same engine:
- Royal Enfield Meteor 350: Relaxed cruiser for everyday riding
- Royal Enfield Classic 350: Retro roadster with timeless styling
- Royal Enfield Hunter 350: Lightweight urban bike
- Royal Enfield Bullet 350: Classic standard with minimalist design
All versions share the same frame, suspension, engine, and braking components, so maintenance is identical across the range. There have been no platform-level mechanical changes since the 2022 release.

Royal Enfield Classic 350 Service Intervals
The basic service interval for the Royal Enfield Classic 350 is every 3,000 miles (5,000 km) or 6 months, whichever comes first.
Valve clearance inspection is also required every 3,000 miles (5,000 km) or 6 months, and is considered part of the standard service not a separate major service. The use of screw-and-locknut adjusters on this SOHC engine makes valve checks relatively simple compared to shim-under-bucket systems.
Basic Service Interval Schedule
- Oil and Filter Change: Every 6,000 miles / 10,000 km or 12 months
- First Service (Break-in): At 300 miles / 500 km or 1.5 months from new
General Notes on Serviceability of the Royal Enfield Classic 350
The Classic 350 uses a 349cc air/oil-cooled single-cylinder engine with a 5-speed gearbox and counterbalanced crank. All service points are easily accessible, and the absence of complex electronics makes home servicing feasible. No diagnostic tools are required for standard checks, although authorized dealers can perform deeper inspections or firmware updates if necessary.
This maintenance schedule continues beyond 30,000 miles / 50,000 km in the same repeating pattern unless more frequent service is needed based on riding conditions.
Royal Enfield Classic 350 Maintenance Schedule Tables
Below is the maintenance schedule for the Royal Enfield Classic 350. It’s based on the official owner’s manual but reorganized into a clearer, more user-friendly format.
The schedule is divided into three parts:
- Regular service: Every 600 miles / 1,000 km, or after any major ride
- Periodic maintenance: A long-term schedule based on mileage and time intervals
- Annual service checklist: Recommended checks to perform once a year, even if mileage is low
General Notes on the Maintenance Schedule
- After the final service listed in the chart (50,000 km), continue repeating the same pattern at the same intervals unless otherwise advised by a dealer.
- Basic maintenance such as oil and filter changes, chain cleaning, air filter servicing, spark plug inspection, and cable lubrication can be done at home with standard tools.
- Valve clearance checks use screw-and-lock adjusters and may be DIY-friendly for experienced home mechanics, though some may prefer to have this done by a technician.
- Some items such as brake fluid changes or emissions hose checks may be easier or safer to perform at a service center.
- The air filter should be cleaned every 10,000 km / 6,000 miles and replaced every 20,000 km / 12,000 miles, but more often if you ride in dusty or wet conditions.
- The drive chain requires cleaning, lubrication, and adjustment every 500 km / 300 miles or more often after rain or dirty conditions.

Tire sizes and pressures for the Royal Enfield Classic 350
Royal Enfield Classic 350 recommended models are CEAT / MRF tires. Replacement tires are Metzeler.
Here are the tire sizes and recommended pressures.
| Wheel | Tire size | Tyre pressure (cold, single rider) |
|---|---|---|
| Front | 100/90 – 19 M/C 57 P | 32 psi/2.24 kg/cm2 |
| Rear | 120/80 – 18 M/C 62 P | 32 psi/2.24 kg/cm2 |
The manual also has suggested tyre pressures for if you have a pillion and even bags. But that isn’t a common use case. I’d suggest you find your own ideal pressure in that (somewhat unusual and thus very variable) situation.
About the Royal Enfield Classic 350
The Royal Enfield Classic 350 is one of those bikes that wears its heritage on its sleeve, and proudly so. This is a proper single-cylinder roadster that doesn’t just borrow retro cues, it lives them. The Classic 350 was re-released in 2022 as a ground-up redesign, built on the new J-platform engine and chassis that first appeared on the Meteor 350. It looks like a vintage machine lifted from a postwar postcard, but everything underneath is new and significantly better than what came before.
At the heart of the bike is a 349cc air and oil-cooled SOHC single, with fuel injection and a counterbalanced crank. Power figures are modest, with 20 horsepower at 6,100 rpm and 19.9 pound-feet of torque at 4,000 rpm. But this isn’t a bike about numbers. It thumps along in a smooth, predictable, and relaxed manner, especially at low to mid revs. The five-speed gearbox shifts cleanly, and the cable clutch is light and consistent. Short-shifting feels natural, and urban riding is where the Classic really comes into its own.
The frame is a steel twin-downtube spine, simple and sturdy. It feels carved from stone, and the 430-pound curb weight reinforces that impression. The suspension setup is straightforward — a 41mm conventional fork at the front and twin shocks at the rear. It has just over five inches of travel up front and three and a half inches in the back. That’s enough for everyday use in town or on backroads, though you’ll find its limits if you start pushing harder.
Braking is handled by ByBre. There’s a 300mm disc and two-piston caliper up front, with a 270mm disc at the rear. Both ends come with ABS. Lever feel at the front is a bit soft, but stopping power is sufficient with a little planning. It’s more than enough for the kind of riding this bike is built for.
Trim options vary by region, however all share the same engine, frame, and running gear. Seat height is an approachable 31.7 inches, and with wide bars and upright posture, it’s an easy, natural ride.
Compared to the older UCE-based Classic, the J-platform version is a major leap forward. Vibration is reduced, shifting is improved, and overall build quality is better. The analog speedometer is paired with a small LCD screen, and some versions come with the Tripper navigation pod, depending on the market.
Maintenance is simple and hands-on. Oil and filter changes, valve checks, chain adjustments — it’s all accessible without special tools or training. It’s the kind of bike that invites you to work on it, not fear it.
