BMW C 400 GT 2025 & C 400 X 2025 Maintenance Schedule and Service Info
This is the maintenance schedule and associated service intervals for the BMW C 400 GT and C 400 X. These models share the same 350cc liquid-cooled, four-valve single-cylinder engine, matched to a continuously variable transmission (CVT). Both models have been based on this engine platform.
Both scooters are rated for A2 license compliance in relevant regions, producing a claimed 34 hp at 7,500 rpm and 26 lb-ft (35 Nm) of torque at 5,750 rpm. The C 400 GT and C 400 X use a steel bridge-type frame, with telescopic fork front suspension and twin shock rear suspension, and are equipped with BMW Motorrad ABS Pro, Dynamic Traction Control, Dynamic Brake Control, and Engine Drag Torque Control as standard on the latest models.
Recent updates (2025) include a Euro 5+ compliant engine, lean-sensitive ABS, an upgraded 6.5-inch TFT dash (with optional 10.25-inch screen), increased underseat storage, and a new manually adjustable windscreen on the GT. The C 400 X also features hand guards and a revised front fairing. Accessory options, such as an enlarged 43.5L top case, are now available.
Maintenance requirements remain unchanged despite these updates. All core service intervals and procedures are the same for both the C 400 GT and C 400 X, regardless of minor feature or trim changes, or regional differences in availability

BMW C 400 GT & C 400 X Service Intervals
The basic service interval for the BMW C 400 GT & C 400 X is every 6,000 miles / 10,000 km or every 12 months, whichever comes first. At each service, change the engine oil and oil filter, check and clean the spark plug, and inspect the air filter. Also, check the coolant level and inspect the brake pads, fluid, and hoses for wear or leaks. BMW recommends inspecting the drive belt at regular intervals for signs of wear.
Valve clearance inspection is a major service item, due every 12,000 miles / 20,000 km. The engine is a single-cylinder layout, which makes access for valve checks relatively straightforward compared to multi-cylinder scooters.
Other regular checks include inspecting the tires for tread and pressure, checking all lighting and electrical systems, and lubricating pivot points. Replace the final drive oil according to the schedule in the owner’s manual. Service the CVT drive system as specified. For most riders, a standard service every 6,000 miles / 10,000 km keeps the scooter reliable and ready to go.
Basic Service Schedule
- First service: 300 – 750 miles / 500 – 1,200 km
- Standard Service: Every 6,000 miles / 10,000 km or 12 months
- Valve check: Every 12,000 miles / 20,000 km
General Notes on Serviceability for the BMW C 400 GT & C 400 X
- The C 400 GT and C 400 X use a water-cooled, single-cylinder, four-stroke engine with a CVT transmission. This setup keeps routine servicing straightforward, with easy access to the spark plug, oil filter, and air filter.
- Both models require regular checks and changes of engine oil, final drive oil, and coolant. Make sure to use only BMW-approved fluids and follow recommended intervals for each.
- Valve clearance inspection comes up every 12,000 miles / 20,000 km. The single-cylinder layout means fewer shims or adjustments than a twin, but check the service manual for proper procedures.
- The CVT belt and rollers are wear items. Inspect them at scheduled intervals and replace if there’s any sign of cracking or excessive wear.
- Always torque fasteners to the specifications in the manual, especially on the brakes and suspension, and check ABS and traction control sensors after any wheel or brake work

About the BMW C 400 GT & C 400 X
The BMW C 400 GT and C 400 X 2025 are BMW’s answer to the modern urban mobility challenge. These two scooters do more than just get you across town; they deliver a real taste of the full-size BMW experience, whether you’re commuting to work or heading out for a weekend escape. Both models run the same 350cc water-cooled single, kicking out 34 hp at 7,500 rpm and 35 Nm at 5,750 rpm. Don’t let the “scooter” label fool you. This is a robust powertrain, EU-5+ approved, with a proper CVT twist-and-go setup and enough muscle to make highway merges and two-up touring genuinely possible.
Between the two, the C 400 X is built for city agility, with a more dynamic front end and a slightly lighter build. The C 400 GT, on the other hand, is set up for touring, offering more wind protection, extra storage, and a manually adjustable windscreen for those longer days on the road. Both have picked up serious upgrades lately. BMW Motorrad ABS Pro is now standard, giving you lean-sensitive braking. Dynamic Traction Control and Engine Drag Torque Control add to the electronic safety net, all working behind the scenes to keep things stable on wet tram tracks or in a hard stop from speed.
What about the ride? The chassis uses a steel bridge-type frame, with a powerset swingarm designed for rigidity. Suspension comes via a telescopic fork up front and twin shocks at the rear, tuned for real-world city bumps and potholes. You get twin disc brakes at the front, both with the ABS Pro magic. It’s not exactly a featherweight, with curb weights just under 220 kg, but the weight sits low so the scooter stays well-balanced, even when fully loaded.
Tech is front and center: a standard 6.5-inch TFT dash delivers everything from music controls to navigation (with the BMW Motorrad Connected app). Want more? The GT can be ordered with a massive 10.25-inch split-screen display, just in case you need to track Spotify, your texts, and your next turn all at once. Both models now offer extra underseat storage, with 3 liters more on the X and up to 12 liters more on the GT when you include the new front pockets. A new 43.5L top case is available too, with USB charging and interior lights, plus a beefier rack that’ll actually handle your weekly shop.
The “Rugged” variant of the C 400 X spices things up with off-road-inspired looks, hand guards, and colored wheels, while the GT “Exclusive” trim adds a diamond white finish, gold highlights, and even logo floor lighting for that little extra flash when you park up at night.
Service intervals land at every 6,000 miles / 10,000 km, and major valve clearance checks only pop up every 12,000 miles / 20,000 km. With just one cylinder to check and everything designed for access, regular maintenance is about as hassle-free as you’ll find in this class.
If you’re after a scooter that actually rides like a “real” BMW, with the tech and finish you’d expect and practical touches that make life easier, the C 400 GT and C 400 X make a strong case. Whether it’s your daily commute, a quick getaway, or just getting through the daily grind, these scooters do more than just get the job done. They bring a bit of that BMW edge to every ride.
