Harley-Davidson X440 (2024+) Maintenance Schedule and Service Intervals
This is the maintenance schedule and associated service intervals for the Harley-Davidson X440. It’s the same across all model variants as they share the same engine and core components.
The Harley-Davidson X440 is built on an all-new platform developed jointly by Harley-Davidson and Hero MotoCorp for the Indian market. It is powered by a 440 cc air-oil-cooled single-cylinder, four-stroke engine with bore and stroke of 79.6 mm x 88.4 mm, a 9.5:1 compression ratio, and electronic fuel injection. Output is a claimed 27 hp (20 kW) at 6,000 rpm and 28 lb-ft (38 Nm) at 4,000 rpm.
The steel trellis frame uses a 43 mm KYB inverted fork up front and twin rear shocks with seven-step preload adjustment. Braking is via a 320 mm single front disc with a twin-piston ByBre caliper and a 240 mm rear disc with a single-piston caliper, both with dual-channel ABS.
Since launch in 2023, there have been no mechanical changes that would alter service requirements. All models use the same service intervals specified in the owner’s manual, including 10,000 km / 12-month major service intervals, with more frequent checks for chain condition and lubrication.

Harley-Davidson X440 Service Intervals
The basic service interval for the Harley-Davidson X440 is every 6,000 miles / 10,000 km or 12 months, whichever comes first. At each service, replace the engine oil and filter, and follow the maintenance schedule for other inspections, adjustments, lubrication, and replacements. The X440’s single-cylinder layout keeps major service straightforward, with all key components easily accessible.
General Notes on Serviceability of the Harley-Davidson X440
- The X440 uses a 440 cc air-oil-cooled single-cylinder engine with a simple SOHC layout. This makes valve clearance checks and other top-end service straightforward, with good access to the cylinder head.
- Engine oil and filter changes are needed every 10,000 km or 12 months. The oil strainer should be cleaned at the same time. Use the specified grade and ensure the magnetic drain plug is cleaned during each oil change.
- The drive chain needs frequent attention. Inspect, clean, lubricate, and adjust every 1,000 km or sooner if ridden in wet or dusty conditions.
- Brake fluid should be replaced every two years or 30,000 km. Check pads, discs, and operation at every service.
- The air filter and other components require more frequent servicing if used in rain, dust, or high-throttle conditions. Always replace gaskets, O-rings, and cotter pins when reassembling.
- Service more often if the riding in wet or dusty conditions, in rain, or at sustained high throttle.
- After washing, wipe off all water with a clean, soft cloth or use pressurized air to dry completely.

About the Harley-Davidson X440
The Harley-Davidson X440 is not your typical Motor Company heavyweight. It is a purpose-built single, designed with Hero MotoCorp in India, aimed squarely at the growing mid-capacity market. Think of it as Harley’s answer to bikes like the Royal Enfield Classic 350 or Honda H’ness CB350, but with a bit more poke and sharper handling.
At its heart is a 440 cc air-oil-cooled single-cylinder engine with a bore and stroke of 79.6 x 88.4 mm, a 9.5:1 compression ratio, and fuel injection. It delivers 27 bhp at 6,000 rpm and 38 Nm of torque at 4,000 rpm, which makes for a strong midrange and relaxed cruising. With a six-speed gearbox, assist and slipper clutch, and a single-side exhaust, the X440 blends old-school thump with modern ease of use.
The chassis is a steel trellis frame suspended by a 43 mm KYB upside-down fork and twin gas-charged rear shocks, adjustable for preload. Braking comes from a 320 mm front disc with a twin-piston ByBre caliper and a 240 mm rear disc, both with dual-channel ABS. The combination of an 18-inch front wheel and 17-inch rear keeps steering stable without feeling lazy.
Harley offers three versions. The base Denim has wire-spoke wheels and a single-colour finish. The Vivid adds cast alloy wheels and two-tone paint. The top-spec S goes for diamond-cut alloys, matte paint, 3D tank medallion, and the full H-D Connect telematics package with SOS alert, theft/accident notifications, geofencing, and remote immobilisation. All get LED lighting, a 3.5-inch TFT display with phone connectivity, turn-by-turn navigation, and a USB charging port.
Ergonomics are neutral and comfortable, with an 805 mm seat height, wide bars, and mid-mounted pegs. At 190.5 kg kerb, it is light for a Harley but still feels solid. Fuel capacity is 13.5 litres, giving decent range for urban commuting and weekend trips.
Maintenance is straightforward thanks to the single-cylinder layout. Major service intervals are every 10,000 km or 12 months, with more frequent checks for the chain, air filter, and other wear items in dusty or wet conditions. Valve clearance inspections are part of the regular service schedule, but access is uncomplicated compared to multi-cylinder machines.
On the road, the X440 feels planted and predictable. It is not a bike for chasing lap times, but the combination of midrange torque, stable handling, and modern safety kit makes it well suited to city traffic, backroad cruising, and even longer hauls. In a market where heritage singles still dominate, Harley has carved out something familiar yet fresh, a bike that carries the badge with pride while playing in a different league.
