2017 Honda CRF125F Overview

For 2017, Honda offers the CRF125F as a cross / motocross motorcycle. The 2017 Honda CRF125F is built around a Single cylinder, four-stroke engine running Single Overhead Cams (SOHC) valve actuation, a compression ratio of 9.5:1. Internally, bore and stroke are 52.4 x 57.9 mm. Out on the road, the CRF125F delivers 10.20 Nm @ 4500 Revolutions of torque. In everyday use, the 2017 CRF125F tips the scales at 88 kg, carries a 4.30-litre fuel tank, offers a seat height of 735 mm and spans a 1,219 mm wheelbase. That's roughly 21.8 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 2017 Honda CRF125F spec sheet below.

2017 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 2017 Honda CRF125F comes out as follows.

With 735 mm, the CRF125F has the 14th lowest seat height of 200 bikes in the Cross / motocross category, 18% below the category average of 901 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 106 models within five model years of it, the seat height of 735 mm is lower than that of 101 of the other 105.

Versus the 2016 model

The figures we track are unchanged from the 2016 model: peak torque, wet weight and seat height all match.

2017 CRF125F - Pros & Cons

Strengths

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 735 mm, flat-footing at a stop is easy for most riders - a genuine confidence builder for less experienced owners.

Considerations

Carburetor fuelling: Carburetion is more hands-on than fuel injection - plan on periodic jetting and cleaning as part of routine ownership.
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 4.30-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

Carburetor maintenance

Being carbureted, the CRF125F is more sensitive to stale fuel and altitude changes than a fuel-injected bike - a carb clean and rejet restores crisp throttle response after any extended lay-up.

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 telescopic 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 2017 Honda CRF125F 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 9 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 single cylinder, four-stroke engine - keep to the manufacturer's interval rather than stretching it. With a 9.5:1 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.

Carburetor upkeep

A CRF125F that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.

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.
