2023 Honda CRF125F Overview
For 2023, Honda offers the CRF125F as a cross / motocross motorcycle with 124.9 cc on tap. The 2023 Honda CRF125F is built around a Single cylinder, four-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 9.0:1. Internally, bore and stroke are 52.4 x 57.9 mm. Out on the road, the CRF125F delivers 10.2 Nm @ 4500 rpm of torque. In everyday use, the 2023 CRF125F tips the scales at 88 kg, carries a 3.79-litre fuel tank, offers a seat height of 739 mm and spans a 1219 mm wheelbase. That's roughly 21.9 kg lighter than the average cross / motocross motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2023 Honda CRF125F spec sheet below.
2023 Honda CRF125F compared with other bikes in the Cross / motocross category
Measured against other bikes in the Cross / motocross category in our database (up to 200 models, one entry per model), the 2023 Honda CRF125F comes out as follows.
- With 739 mm, the CRF125F has the 14th lowest seat height of 200 bikes in the Cross / motocross category, 18% below the category average of 900 mm.
- Torque of 10.2 Nm is lower than that of 48 of the other 58 bikes in the Cross / motocross category.
- Only 28 of the other 128 bikes in the Cross / motocross category have a lighter wet weight than the 88 kg of the CRF125F.
- Narrowing the field to the 89 models within five model years of it, the seat height of 739 mm is lower than that of 84 of the other 88.
Versus the 2022 model
The figures we track are unchanged from the 2022 model: peak torque, wet weight, displacement and seat height all match.
2023 CRF125F - Pros & Cons
Strengths
-
🔧
Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
-
🛑
Strong front braking: The single disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.
-
📏
Accessible seat height: At just 739 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.
Considerations
-
🛑
Drum rear brake: A drum rear brake is simple and durable, but expect less bite and more fade under hard, repeated use than a disc setup.
-
⛽
Modest fuel capacity: A 3.79-litre tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.
-
⚙️
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.
Wear Points & Servicing Notes
Fuelling & injector care
Fuelling on the CRF125F comes from fuel injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.
Valve clearance checks
Valve clearances on Single Overhead Cams (SOHC)-equipped engines like the CRF125F's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.
Brake disc and pad wear
Single disc with hydraulic up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.
Suspension condition on used examples
Suspension duties are handled by 31mm leading-axle fork up front and Pro-Link single-shock at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.
Final drive maintenance
Chain final drive on the CRF125F means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.
Frame & chassis check
The Diamond, steel chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
Low-speed handling
The CRF125F's 88 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.
CRF125F - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2023 Honda CRF125F with its 124.9 cc cross / motocross should cover the same ground every time: service history, drivetrain condition, and any oil seepage around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 3 years old, this cross / motocross is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept CRF125F settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for the CRF125F's 124.9 cc single cylinder, four-stroke - keep to the manufacturer's interval rather than stretching it. With a 9.0:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.
Fuel system care
Injector systems like the CRF125F's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
Valve clearance service
There's no reliable seat-of-the-pants way to tell if a CRF125F's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
