TL;DR
- Honda CRF125F: 125cc air-cooled four-stroke, fuel injection, 4-speed manual clutch, electric start, 29.1 in seat, 194 lb curb weight, front disc and rear drum. $3,599 MSRP plus $300 destination; Big Wheel $3,999 plus $300.
- Honda does not publish a top speed or a rider weight limit. Owners report roughly 40 to 45 mph. The FRP FX125 publishes both: about 56 mph and a 265 lb rider load.
- The CRF125F wins on fuel injection, dealer network and resale. The FX125 answers with hydraulic disc brakes at both ends, a published load rating, two wheel sizes with two seat heights, and direct parts supply.
- Best for: a family that wants a dealer-backed Honda and one seat height. Not right for: heavier riders who need a published limit, riders who want a rear disc, or anyone who needs the bike to grow from a 28 in seat to a 34 in seat.
The Honda CRF125F is the benchmark 125cc trail bike for riders stepping up from a 50cc or 110cc, and it is the bike most parents have in mind when they search "125 dirt bike." It has a 20-year reputation, a dealer on most highways, and a fuel-injected engine that starts in the cold. This review covers what Honda's own specification sheet says the CRF125F delivers, what it leaves out, and where the FRP Moto FX125 fits for the same rider.
Honda's published figures for the 2026 and 2027 CRF125F: a 125cc single-cylinder four-stroke with a 52.4 x 57.9 mm bore and stroke, 9.0:1 compression, programmed fuel injection through a 22 mm throttle body, a four-speed gearbox with a 13/46 final drive, a 31 mm fork with 5.9 in of travel, Pro-Link rear suspension with 5.5 in of travel, a 220 mm front disc, a 95 mm rear drum, a 29.1 in seat, 8.3 in of ground clearance, a 1.0 gal tank and a 194 lb curb weight with fluids. The two numbers buyers ask about most, top speed and rider weight limit, are not on that sheet.

How fast does the Honda CRF125F go?
Honda does not print a top speed, and that is deliberate: the CRF125F is sold as a youth trail bike, and its gearing is chosen for control rather than a headline number. With the stock 13/46 final drive, a light rider and flat hard-packed ground, owners consistently report the standard model in the 40 to 45 mph range. Add a heavier rider or soft dirt and it settles into the high 30s. The Big Wheel, with its 19 in front and 16 in rear, rolls a little taller and gains a couple of miles per hour at the top while losing a little off the bottom.
The FX125 runs the same displacement and gearbox count but FRP publishes its figure, about 56 mph, alongside the 265 lb load rating. The useful comparison is not the number itself but what each bike is set up to do: the CRF125F is geared to keep a first-time clutch rider calm, and the FX125 in its 17/14 build is geared to move a teen or adult on open trail. A 12-year-old on either bike will not see the top of the gearbox for a season.
Who should buy the Honda CRF125F?
The CRF125F is the right choice if:
- You want fuel injection, because the rider is not going to learn a choke and the bike will sit for weeks between rides.
- You want a Honda dealer to handle warranty, service and resale, and you are near one.
- One seat height is enough: the rider is already comfortable at 29.1 in and is not going to grow past it in the next two seasons.
- You are riding where the CARB certification matters, such as California OHV areas.
Who should NOT buy the Honda CRF125F?
The CRF125F is the wrong choice if:
- The rider is a heavier teen or an adult and you want a published weight rating to check against. Honda does not give one; the FX125's is 265 lb.
- You want a disc brake at the back. The CRF125F still carries a 95 mm rear drum; the FX125 has hydraulic discs at both ends.
- You need the seat height to move with the rider. The FX125 comes as a 28.1 in small-wheel build or a 33.9 in big-wheel build on the same engine; the CRF125F offers 29.1 in or the Big Wheel, each a separate purchase.
- You want to buy wear parts from the same place you bought the bike, without a dealer parts counter in between.
FX125 vs CRF125F: the practical decision
The CRF125F's edge is fuel injection, the Honda dealer network and resale value. The FX125 answers with hydraulic discs front and rear, a 265 lb published load rating, two seat heights on one engine, and parts sold direct. For a rider who is still growing, or a teen or adult who wants the rating in writing, the FX125 is the more flexible bike. For a family that wants one dealer relationship and does not expect the rider to outgrow a 29 in seat, the CRF125F does what it promises.
What are the Honda CRF125F's real strengths?
- Fuel injection. The PGM-FI system with a 22 mm throttle body starts in cold weather, needs no choke, and does not foul a carburetor when the bike sits. For a young rider or a parent who does not want to think about fuel, this is the biggest practical advantage over any carbureted 125.
- A gearbox that teaches. The four-speed with a heavy-duty manual clutch is the same pattern as a full-size Honda. A rider who learns to shift on a CRF125F carries that straight onto a CRF250F later.
- Dealer network and resale. Honda's trail bikes hold value, and there is a dealer in most towns for warranty and service. The six-month warranty is transferable.
- CARB certification. The CRF125F meets California off-road emissions standards, which matters if your riding area requires a green sticker. The FX125 is not sold in California.
What are the Honda CRF125F's main weaknesses?
- No published rider weight limit. The specification sheet gives a 194 lb curb weight and suspension travel, but nothing for the rider. A heavier teen or an adult is guessing. The FX125 states 265 lb.
- Rear drum brake. A 95 mm drum stops a 194 lb bike and a light rider fine, but it fades on long descents and is harder to modulate than a disc. The FX125 has hydraulic discs at both wheels, with a dual-piston front caliper on the 17/14 build.
- One seat height per model. The standard CRF125F is 29.1 in and the Big Wheel is taller; changing means changing bikes. The FX125 keeps the same engine and puts it in a 28.1 in or a 33.9 in chassis, so the same order can fit a 12-year-old or an adult.
- Dealer-only purchase and parts. The MSRP is a starting point; destination, dealer setup and fees are added at the counter, and parts go through the same counter. FRP sells the FX125 direct with wear parts on the same site.
How does the CRF125F compare to the Big Wheel and the CRF110F?
The CRF125F Big Wheel is the same engine and frame on 19 in front and 16 in rear wheels, with a taller seat and more ground clearance, at $3,999 plus $300 destination. It is the version for a taller teen. One step down, the CRF110F is a 109cc fuel-injected automatic-clutch bike at $2,799 plus $300 destination, aimed at a rider who is not ready to work a clutch.
The FRP lineup covers the same ladder differently. The FX40 is the 40cc starter, the FX125 covers both the small-wheel and big-wheel roles on one engine, and the FX140 is the oil-cooled step up. The FX125 product page lists both builds side by side, and the full FRP dirt bike lineup shows where the FX140 takes over.
Is the Honda CRF125F the right buy?
What the CRF125F delivers is exactly what Honda lists: a fuel-injected 125 with a real clutch, a 29.1 in seat, 194 lb wet, a front disc and a rear drum, backed by a dealer. What it does not deliver is a top speed, a weight rating, a rear disc, or a second seat height without a second purchase.
For a family near a dealer, with a rider who fits a 29 in seat now and will for a while, the CRF125F is a safe, well-supported choice. For a rider who is still growing, a heavier teen, or an adult who wants the numbers in writing, the FX125 covers more ground with one bike: two seat heights, a 265 lb rating, discs at both ends, and parts from the same place you bought it. The FX125 125cc dirt bike page has the seat height and load rating for each build, and the gas dirt bikes collection puts the FX40, FX125 and FX140 on one page.
FAQ
What is the top speed of the Honda CRF125F?
Honda does not publish one. Owners report the standard model around 40 to 45 mph on flat ground with a light rider, and the Big Wheel a little higher. Rider weight, terrain and the stock 13/46 gearing all change the number.
What is the weight limit on a Honda CRF125F?
Honda does not publish a rider weight limit. The bike weighs 194 lb wet with 5.9 in front and 5.5 in rear travel and is sold as a youth and beginner trail bike. If you need a published rating, the FX125 is rated to 265 lb.
Is the Honda CRF125F a 2-stroke?
No. It is a 125cc air-cooled single-cylinder four-stroke with a single overhead cam, two valves and fuel injection. It runs on straight gasoline with no premix.
Is the Honda CRF125F street legal?
No. It is certified as an off-road motorcycle and ships with no lights, mirrors or signals. Whether one can be made street legal depends on your state. The same applies to every bike in the FRP dirt bike lineup: off-road use only.
How much does a Honda CRF125F cost, and where do you buy one?
Honda lists the 2026 and 2027 CRF125F at $3,599 MSRP plus $300 destination, and the Big Wheel at $3,999 plus $300. Both are sold only through Honda dealers, so tax, setup and dealer fees are added on top.
Where to go from here
If the rider fits a 29 in seat and you want a dealer-backed Honda, the CRF125F is a sound choice. If you want a published weight rating, discs at both ends and a bike that comes in two seat heights, look at the FX125.
