CFMOTO 800 MT-X (2025+)Maintenance Schedule and Service Info

This is the maintenance schedule and associated service intervals for the CFMOTO 800 MT-X. It applies to all production years since its release in 2025, as the motorcycle is based on the same platform and engine throughout.

The CFMOTO 800 MT-X is built on the KTM-derived 799cc “LC8c” parallel twin engine, shared with models like the Ibex 800 and the KTM 790 Adventure. It’s a liquid-cooled, 8-valve DOHC twin with a compression ratio of 12.7:1, producing 70 kW (94 hp) at 8,500 rpm and 87 Nm of torque at 6,750 rpm.

Here are all the motorcycles that share the same basic engine and maintenance profile:

• CFMOTO Ibex 800 (a.k.a. 800MT in some regions)
• CFMOTO 800NK (street naked, same engine but different chassis and tune)
• KTM 790 Adventure
• 790 Duke

The 800 MT-X differs from its sibling, the Ibex 800, by offering longer-travel suspension (230 mm front and rear), a lighter chassis, and a 21/18 inch spoked wheel combo for better off-road capability. It also uses low-slung dual fuel tanks similar to the KTM 790 Adventure, though an optional 8L auxiliary tank can be added.

The core maintenance is shared across the range of 799cc LC8c-powered models. The main variation is in suspension setup and component accessibility, but not in the schedule of service items themselves. Notably, the 800 MT-X uses J.Juan brakes rather than the Brembo units shown on the early concept, and the fork and shock are KYB-branded and fully adjustable.

No major changes have been made to the engine, emissions systems, or core chassis components since release. Therefore, the maintenance intervals remain consistent for all 800 MT-X motorcycles to date

CFMOTO 800 MT-X (2025+) Service Intervals

The oil change service intervals for the 800 MT-X vary by region. In the United States, CFMOTO recommends changing the oil and filter every 3,000 miles / 5,000 km or 12 months, whichever comes first. This interval also includes a broad range of checks, including the battery, electrical system, and suspension, which is not typical. If you ride regularly, you can likely postpone many of these checks until the 10,000 km inspection.

In most other markets, the oil and filter change interval is much longer: 9,000 miles / 15,000 km, similar to the schedule for the KTM 790 platform on which the engine is based.

The valve clearance check interval is generous set at 18,000 miles / 30,000 km.

Since the CFMOTO 800 MT-X uses a liquid-cooled engine, coolant should be replaced every four years. Brake fluid, as usual, should be replaced every two years to maintain braking performance.

Maintenance schedule for the CFMOTO 800 MT-X

The maintenance schedule for the CFMOTO 800MT-X is different from other bikes in the CFMOTO lineup because the engine comes from a different source. It’s a KTM motor dressed in CFMOTO bodywork (and pricing).

As a result, the 800 MT-X benefits from the same generous service intervals you’d find on KTM motorcycles. That’s a welcome change compared to the tight 5,000 km oil change intervals of the 700CL-X.

That said, the official maintenance schedule in the manual can be a bit of a mess. Some items have oddly specific intervals, like every 10,000 km or one year, while others are every 30,000 km or four years. There’s no clear reasoning given, so instead of trying to decode each one, it’s easier to just focus on the shorter interval and keep things straightforward.

To make it more manageable, we’ve split the maintenance into two sections:

• The regular or annual maintenance
• The periodic service schedule

General Notes on Serviceability for the CFMOTO 800 MT-X

• The 800 MT-X uses the KTM-derived 799cc LC8c parallel twin engine, which is a liquid-cooled, DOHC design with 8 valves. Valve clearance checks are required every 30,000 km, and access is moderately involved due to the low-slung fuel tanks and bodywork.
• Engine oil capacity is 2.8L with a filter change. CFMOTO recommends SAE 10W-50 oil meeting JASO MA2 spec. Oil changes are straightforward, but access to the oil filter requires removal of the lower panel and parts of the skid plate.
• The bike uses a pressurized liquid cooling system with a combined radiator and expansion reservoir. Recommended coolant is CFMOTO Organic (OAT type). Allow at least 2 minutes after shutdown before checking coolant level to ensure pressure has equalized between the split fuel tank design.
• Chain drive maintenance is typical for the class, with a recommended inspection every 1,000 km. The spoke wheels and off-road geometry mean the rear axle and adjusters are exposed. Keep these clean to prevent corrosion and misalignment during adjustment.
• Suspension setup is fully adjustable front and rear, with rebound, compression, and preload. Riders making changes should record baseline settings, as KYB does not label damping increments. Use care when adjusting preload collars or knobs to avoid over-tightening.

Regular / Annual Service Checklist

Below is the annual service checklist for the CFMOTO 800 MT-X. This is a list of things to check at every service, according to the schedule below.

Periodic Maintenance Schedule for the CFMOTO 800 MT-X

Below is the periodic maintenance schedule for the CFMOTO 800 MT-X from the US manual.

Notes:

• At the end of the maintenance schedule, keep following it in the pattern shown.
• The break-in schedule is not shown, but it’s essentially an annual service and oil / filter change.

Note: The US manual calls for oil and filter changes, as well as oil screen cleanings, every 3,000 miles. In contrast, the manual for other markets sets the oil change interval at 9,000 miles / 15,000 km. Aside from this difference, the service schedules are the same.

About the CFMOTO 800 MT-X

The CFMOTO 800 MT-X is CFMOTO’s first serious swing at a real off-road-ready middleweight adventure bike, and it’s got some real teeth. If you’ve seen the Ibex 800/800MT, you might think this is just a re-skinned version with a dirtier attitude. But the MT-X is more than just graphics and suspension tweaks. It’s been purpose-built to go deeper into the wild, with a sharper spec sheet and a lighter, leaner approach to the platform.

At the core is the same 799cc LC8c parallel twin that CFMOTO builds for KTM. It’s a liquid-cooled, DOHC 8-valve motor with a 12.7:1 compression ratio, shared with the KTM 790 Adventure and Duke, and it makes 95 horsepower at 8500 rpm and 87 Nm of torque at 6750 rpm. That’s the same basic package as the Ibex 800, but the MT-X is tuned to hit its torque peak earlier, which gives it more punch down low when you’re standing on the pegs and crawling up something nasty. The engine is paired with a slipper clutch, a quickshifter in both directions, and an electronic throttle with three ride modes: Sport, Rain, and Offroad.

Where the Ibex is a soft-roader with some adventurous styling, the MT-X goes all in. It rides on a 21-inch front and 18-inch rear wheel combo, with fully adjustable KYB suspension giving 230 mm of travel at both ends. Ground clearance jumps to 240 mm with the high seat fitted, and the dry weight drops to 196 kg. The front brake setup is a pair of 320 mm discs with J.Juan radial-mount calipers, and a 260 mm disc at the rear, all managed by a Bosch IMU with cornering ABS and traction control.

The fuel tanks (yes, tanks plural) are mounted low on either side of the frame, KTM-style, holding 22.5L between them and keeping the center of gravity nice and low. There’s also an optional rear-mounted auxiliary tank that adds another 8L if you’re heading somewhere remote. The bodywork is trimmed for movement, with a flat, rally-style one-piece seat and a tall, adjustable windscreen. Even better, the air filter is under the seat for quick cleaning, and there’s a built-in storage slot for an onboard air pump.

Tech-wise, you get a vertical 7-inch TFT dash with automatic brightness adjustment, Bluetooth, cruise control, USB-A and USB-C charging, a tire pressure monitoring system, and optional T-Box connectivity. There’s even a steering damper and a proper mechanical key, which feels like a win in an age of temperamental keyless systems.

Compared to the Ibex 800, the MT-X is lighter, taller, more aggressive, and simply better suited to actual trail work. The Ibex remains a solid touring bike, but the MT-X is what you want if you’re planning to get it dirty.

Maintenance is fairly standard for a middleweight ADV. Oil changes are due every 5000 km, with valve clearance checks every 30,000 km. Nothing too exotic, though you’ll need to drop the bash plate for most engine work.

In short, the 800 MT-X is a clever remix of KTM parts and CFMOTO’s own adventure design language. It’s not just a cheaper 790. It’s a focused, well-specced, and genuinely dirt-capable machine that’s ready to go exploring.
