This is the maintenance schedule and associated service intervals for the Honda CRF250L.
The Honda CRF250L is a dual-sport motorcycle, part of the Honda CRF series, manufactured by Honda for their global market. It was first released in 2012 for the 2013 model year, and has remained basically unchanged since, until being discontinued in favour of the Honda CRF300L.
The Honda RF250L was also released in the “Rally” trim from 2017, which gave it a small windscreen, slightly more suspension travel, hand guards, skid plate, re-styled fairings, and asymmetrical headlights that remind you quite a bit of a BMW adventure bike.
But the core of the motorcycle is the same — a 249cc water-cooled fuel-injected single that makes 18 kW (24 hp), and is mostly built for not going too fast. It’ll clear 75 mph (or 110 km/h) but barely, and on a straight.
In 2021, Honda upgraded the engine capacity slightly with the CRF300L and CRF300L Rally.
For those looking for a bit more off-road excitement, the CRF450L is higher spec (and more highly strung).

Honda CRF250L Service Intervals
Overall, the Honda CRF250L has 4000 mile / 6400 km oil change service intervals. Every service, do a number of checks, mostly of safety equipment.
Change the oil of the CRF300L every 8000 miles / 12800 km. And a valve clearance major inspection is due every 16000 mi / 25600 km.
Amazingly, the CRF250L’s spark plug doesn’t need to be replaced until a whopping 32000 miles / 51200 km!
Since the CRF250L is liquid-cooled, make sure you keep the coolant fresh.
What you need to service your Honda CRF250L
Maintaining a fuel-injected dual-sport bike is a must! You’re going to get the chain dirty, the air cleaner clogged up, and put the suspension and pivot points through abuse. Aside from regular motorcycle maintenance tools, here are a few other things you’ll need to keep your CRF250L in spec.
|Part||Honda CRF250L and CRF250L Rally|
|Oil||Honda recommends SAE 10W-30, JASO T 903 standard MA (or API classification SG or higher) oil such as Pro Honda GN4 10W-30. Use a torque wrench to tighten the bolt to 24 Nm (18 lb-ft).|
|Oil filter||You can use Hiflofiltro HF112 for the oil filter as a drop-in replacement|
|Air filter (OEM)||You can use the K&N air filter, whose part number is K&N HA-2513.|
|Spark plugs||Use NGK spark plug part SIMR8A9.|
|Chain maintenance||To maintain your chain, Motul chain paste is quite well-liked. There’s also the Motul chain care kit which is affordable and good.|
|Brake fluid||You can use any fluid, but Honda recommends Honda DOT 4.|
|Brake pads (front)||EBC front brake pads have part number FA465R.|
|Brake pads (rear)||EBC rear brake pads have part number FA629R.|
|Coolant||Use Zerex G05, which is based on ethylene glycol, with corrosion inhibitors|
|Grease||Stock up on lithium soap-based grease and silicon grease to keep pivots and moving parts lubricated and protected.|
Honda CRF250L Maintenance Schedule
Below is the maintenance schedule for the Honda CRF250L.
Since the first CRF250L, Honda has revised the maintenance schedule, simplifying it somewhat. These changes apply retrospectively to earlier models as well.
- I = inspect and clean, adjust, lubricate, or replace, if necessary. C = clean, L = lubricate, R = replace
- At higher odometer readings, repeat at the frequency interval established here
- Honda recommends you get a qualified mechanic to service the wheels/tires and steering bearings
- The break-in schedule is not relevant to a bike no longer sold new, so is removed from the below.

Maintaining Your Chain on the Honda CRF250L
It’s important to maintain your chain on the CRF250L, as on any chain-driven motorcycle, but particularly for a dual sport where the chain might get dirty a lot.
Use a good-quality chain lubricant like Motul chain paste, or a Motul chain care kit which comes with a couple of handy tools to maintain the chain.
Honda recommends you follow the following chain maintenance schedule:
|Chain maintenance item||Every|
|Check drive chain lubrication condition, lubricating if necessary||600 mi / 1000 km|
|Check drive chain slack, adjusting if necessary|
Target slack: 25-35mm / 1-1 3/8 inches
|600 mi / 1000 km|
- Do these items (checking/adjusting slack, and checking/applying lubrication) more often if you ride your Honda CRF250L off-road — i.e. if you use your bike as a dual-sport, or in rainy / muddy conditions.
- Always lubricate the chain after washing the motorcycle.
Measure slack on the CRF250L by measuring the maximum deflection in the middle of the bottom part of the chain, moving the chain up and down with your finger.
Target slack: 25-35mm / 1-1 3/8 inches
If the slack is out, adjust it following this procedure:
- Put the motorcycle on its kickstand on a level surface, in neutral.
- Loosen the rear axle nut and the lock nuts on both adjusting bolts.
- Turn the adjusting bolts the same amount, increasing or decreasing the slack. Look at the reference marks to make sure the axle remains aligned. Keep checking the chain slack as you adjust.
- Tighten the axle nut (88 Nm / 65 lb-ft) and the adjusting lock nuts (27 Nm / 20 lb-ft).
Tyre size and tyre pressure for the Honda CRF250L
The Honda manual refers to the following tyre sizes, recommended tyres, and tyre pressures (when cold). These are tubed tyres.
|Front||3.00-21 51P||IRC GP-21F Z||22 psi (150 kPa , 1.50 kgf/cm2 )|
|Rear||120/80-18M/C 62P||IRC GP-22R||22 psi (150 kPa , 1.50 kgf/cm2 )|
About the Honda CRF250L
The CRF250L is the motorcycle industry’s top-selling dual-sport model by a large margin, and it’s easy to understand why. It’s affordable, reliable, and does really well on- and off-road.
With the CRF250L’s long-travel 43mm inverted fork, single-shock rear suspension, styling cues from the bigger bikes in the CRF line (like the Africa Twin), and ABS as an option (and standard in many markets), the CRF250L is an excellent low-cost and low-maintenance adventure bike.
It combines a high-efficiency, fuel-injected dual overhead cam single-cylinder counterbalanced engine and electric starter with a comfortable, neutral seating position.
The core of the Honda CRF250L is a 249.6cc single-cylinder four-stroke engine. It’s the same engine as in the Honda CBR250R, and is produced in Honda’s Thailand production facility.
The tiny single has a dual overhead camshaft layout for better combustion efficiency (the cams are lighter and the valves are smaller), and has a centrally located spark plug for clean burning.
The combination of the lightweight valvetrain and oversquare short-stroke engine means that the engine is quite revvy.
The Honda CRF250L has some high-grade components as well. The front suspension is comprised of a 43mm Showa inverted fork with 250mm (9.8 inches) of travel — enough for a huge variety of terrains. The rear suspension is a Showa shock allowing a whopping 240mm (9.4 inches) of rear wheel travel.
The front brake is just a single 256mm disc gripped by a twin piston caliper, but that’s more than enough for the lightweight CRF250L. The disc is of a wave design, which helps with self-cleaning ability when it gets cake with mud.
The Honda CRF250L is very easy to maintain. Just keep it clean. The services come every 8000 mi (12800 km), but the valve inspection intervals are twice those — every 16000 mi (25600). Considering it’s just a single, the valve service and spark replacement job is a piece of cake.
The Honda CRF250L also comes in higher-spec “Rally” format from 2017-2020. When you get a Honda CRF250L Rally you also get a standard small windscreen, hand guards, skid plate, asymmetrical headlights, and longer-travel suspension. It’s a mini adventure bike. For many of the rougher parts of the world, the CRF250L is more than enough.
The Honda CRF250L was replaced in 2021 by the Honda CRF300L.
Manual for the Honda CRF250L
The above maintenance schedule comes directly from the user’s manual for the 2017-2020 Honda CRF250L.
The manual changed in format since the 2016 model, and some service intervals changed. But fundamentally it’s the same bike, and so this is the latest guidance from Honda on servicing the CRF250L.
