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 10.6 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 CRF125F - Pros & Cons

Strengths

  • 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.
  • 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. 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 should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. 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 a CRF125F's engine - keep to the manufacturer's interval rather than stretching it. 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.
