See it ridden: one owner, one summer
All four clips are the same bike and the same owner, TikTok creator @darzrt, filmed from delivery in June 2026 to race prep for his first county-fair pit bike race at the end of August. He is a sponsored FRP creator; the footage and the opinions are his.
Note on trim: his bike is the FX125 Pro. The digital dashboard, 6-position adjustable levers, high/low beam headlight and adjustable rear shock are Pro-only. Basic builds share the same 125cc engine, 4-speed manual, hydraulic disc brakes and electric plus kick start. Pro stock varies; check the FX125 product page for current builds.
The full first-look review on the creator’s own channel: Darzrt on YouTube.
The short verdict
The FX125 is a 125cc trail and pit bike for teens and adults stepping up to their first real manual clutch. It pairs a 125cc air-cooled Zongshen engine (8.7 hp, about 56 mph) with a true 4-speed manual, hydraulic disc brakes front and rear, electric plus kick start and a 265 lb rider rating, in two wheel sizes with a 28.1″ or 33.9″ seat. It is not built for very young first-time riders or for the street. Off-road only; helmet and full gear every ride.
FRP Moto built its name on beginner-friendly gas mini bikes like the GMB100. The FX125 is the brand’s move into real manual-clutch trail bikes — the kind a rider grows into rather than out of. This review covers the verified specs, the riding experience, build quality, ownership, and exactly who should (and shouldn’t) buy it.
What the owner found over one summer
Delivery and assembly
The FX125 ships in a full metal crate inside a cardboard box. Packed with the bike: gloves, goggles, anti-fog spray, a backpack with a hydration bladder, a tool kit and the manual. Once the packaging came off, the first thing he pointed at was the chassis: forks he called beefy “like an 85”, and a frame and swingarm he called huge for a 125 pit bike. He fitted the front wheel and finished the build himself.
Before the first start: check the oil
He pulled the drain plug before ever starting it and found almost no oil in the engine. Do not assume a new FX125 is ready to run. Check the dipstick and fill with 10W-40 or 10W-50 to the upper mark, as the manual specifies, then add 87+ unleaded fuel. His first electric-start attempt went nowhere because the fuel valve was still closed; once he opened it, the engine started straight away. On a cold engine, the manual calls for the choke. Treat the first 500 miles as break-in and vary engine speed rather than holding it steady.
On the dirt: 52 mph at 195 lb
After a session on a small local pit bike track and a grass hill climb, he reported 52 mph with himself aboard. He is 5′11″ and 195 lb, so that sits just under FRP’s ~56 mph rating. He called the bike “super quick” and said his next step was trying the FX140.
The most-liked comment on that clip asked him to wear a helmet. He put one on before the hill climbs, and it belongs on from the first minute. The crate includes gloves and goggles, not a helmet.
What broke, and what he adjusted
By late August, the one failure he reported was the kickstand spring. He traced it to the kickstand bolt working loose because he never re-checked fasteners after delivery. His advice applies to any new bike, name brand or not: go over every bolt before the first ride and again after the first few. The manual’s pre-ride inspection says the same.
For his first track race he removed the kickstand entirely and rotated the shift lever up so it cleared his moto boots, a short job with hand tools.
What riders asked under the videos
His FX125 videos have drawn well over 1,000 comments on TikTok and YouTube. One question alone, why the bike has both a kick starter and an electric start, collected more than 400 likes. These are the questions that came up most, paraphrased, with answers from FRP’s spec sheet, the owner’s manual and the owner’s own replies.
| Asked in the comments (paraphrased) | Answer |
|---|---|
| Why does it have a kickstart and an electric start? | Backup. Every FX125 build has an electric start button and a kick starter, so a flat battery doesn’t end the ride. |
| Is it manual? Is the clutch hard to learn? | It is a true 4-speed manual with a wet multi-plate clutch on every build. It is a new skill coming off a twist-and-go mini bike; most riders get the basics in an afternoon. |
| How fast does it go? | FRP rates it at about 56 mph. The owner in these videos reports 52 mph at 195 lb. |
| How tall are you? Won’t a 125 be too small? | He is 5′11″. Fit comes from seat height: 28.1″ on the 14″/12″ build, 33.9″ on the 17″/14″ build, with a 265 lb rider limit on both. |
| If I’m 4′5″, can I reach the ground? | Not comfortably on either build; even the lower 28.1″ seat is tall for that height. A smaller bike such as the FX40 is the better fit. |
| Is it fuel injected or carbureted? | Carbureted. The manual lists a PZ26 carburetor with a manual choke for cold starts. |
| Won’t that air filter let dirt in? | It runs an open pod-style filter on the carburetor. In dusty or wet riding, clean and re-oil it more often, as the manual advises, and keep the bike out of deep water. |
| Why not race a 110 instead? | His own TTR110 build wasn’t running, so the FX125 went to the race. He says it is the faster of the two; stock for stock, the FX125 has the larger engine. |
| Is it the same as the FX140? | In the 17″/14″ build they share the chassis, 33.9″ seat and 265 lb rating. The FX140 has a 140cc oil-cooled engine making 11.0 hp against the FX125’s 8.7 hp. |
| Is it street legal? | No. The FX125 is EPA off-road only, not street legal, and not sold in California. |
| How much is it? | $799.99 for the 14″/12″ Basic and $999.99 for the 17″/14″ Basic. |

Performance: real power with a real clutch
The FX125’s headline feature isn’t the ~56 mph top speed — it’s the true 4-speed manual clutch. Coming off a no-clutch mini bike, that’s the big change: you choose the gear, manage power on climbs, and use engine braking on descents. It’s a genuine skill, but most riders get the basics in an afternoon, and it’s what makes the FX125 feel like a real dirt bike rather than a twist-and-go toy.
Power delivery from the 125cc Zongshen is smooth and torquey for the class. The ~56 mph rating is plenty for trail riding; as with any bike, real top speed drops with rider weight, hills and loose ground. The owner in the videos above reports 52 mph at 195 lb. For the full speed breakdown, see the FAQ below.
Build quality: brakes, suspension, frame
The FX125 stops on hydraulic disc brakes front and rear — a step above the cable or mechanical discs common on small-bore pit bikes — with a dual-piston front caliper on the big-wheel build. Suspension is telescopic forks up front with a rear mono-shock; the 17″/14″ build adds longer travel for rougher ground. The steel frame and 265 lb rider load rating are on the stronger end for a 125 in this segment, which is part of why it carries adults that lighter pit bikes can’t.
Two builds: pick the wheel size for the rider
The same 125cc engine comes in two wheel sizes, so the FX125 fits a wide span of riders. Don’t choose on speed — both are rated the same — choose on fit.
For most younger teens the low-seat 14″/12″ build is the fit; taller teens and adults want the 17″/14″. Full breakdown in the FX125 14″/12″ vs 17″/14″ wheel-size guide, or check whether an adult fits a 125cc.
If neither build lands right — too tall for a younger rider, or not enough bike for an adult — the FRP dirt bike range covers 40cc through 140cc with seat height and rider size listed per model.
Who the FX125 is for, and who it isn’t
Best for
- Teens and adults ready to learn a manual clutch
- Riders stepping up from a gas mini bike or 40cc
- Trail and private-property riders who want a bike they grow into
- Adults up to 265 lb who need a 125 that carries them
Not designed for
- Very young or first-time riders with no gas-bike experience
- Anyone who needs a street-legal bike
- Riders who want sustained high-rpm racing (air-cooled — the oil-cooled FX140 suits that better)
- California buyers (not sold in CA)
Reliability, warranty and parts
A common buyer concern is simple: is the FX125 engine actually reliable, and how does warranty support work if something goes wrong? That is the right question to ask before stepping up from a mini bike to a manual 125cc dirt bike.
The FX125 is not a toy-level ride-on. It is a real gas dirt bike with a manual clutch, chain drive, suspension, brakes, oil changes, air-filter service and break-in needs. Reliability depends on both the machine and the owner: correct assembly checks, oil service, chain maintenance, air-filter cleaning, and riding within the bike’s intended off-road use.
Before the first real ride, check oil level, chain slack, brake feel, tire pressure, axle hardware, throttle return and all visible fasteners. During the first few rides, re-check the chain and hardware because new bikes settle under vibration. The owner above learned that one with a loose kickstand bolt.
The FX125 comes with a 1-year limited warranty and ships within 72 hours by LTL freight. It arrives crated and mostly assembled; the owner fits the front wheel and finishes the build, as the unboxing clip shows. FRP Moto stocks replacement and upgrade parts directly, which matters more on a manual trail bike than on a simple mini bike. Routine care is standard 4-stroke: check the oil level before every ride, keep the chain tensioned, and clean and re-oil the air filter, more often in dust or wet conditions.

Questions FX125 buyers ask
Is the FRP Moto FX125 worth it?
For a rider ready to step up from a mini bike or 40cc to a real manual trail bike, yes. It pairs a 125cc engine and a true 4-speed manual clutch with hydraulic disc brakes, two wheel sizes and a 265 lb rider load. Best for teens and adults learning a clutch; not for very young first-time riders or street use.
How fast does the FX125 go?
About 56 mph (90 km/h) as rated. Real-world speed depends on rider weight, gearing, terrain and tune; the owner in the videos on this page reports 52 mph at 195 lb. The 125cc air-cooled Zongshen engine makes 8.7 hp at 7,500 rpm and 8.8 N·m of torque at 5,500 rpm.
Is the FX125 good for beginners?
It is a teen-and-adult step-up bike, not a young child’s first bike. The 4-speed manual clutch is a new skill coming from a no-clutch mini bike, but most riders learn the basics in an afternoon. True first-timers should start on a 40cc like the FX40.
What engine is in the FX125?
A 125cc 4-stroke air-cooled Zongshen engine, 8.7 hp at 7,500 rpm, fed by a PZ26 carburetor, with a 4-speed manual wet multi-plate clutch and chain drive (#420 on the 14″/12″ build, #428 on the 17″/14″). Electric plus kick start.
How much does the FX125 cost?
$799.99 for the 14″/12″ build and $999.99 for the 17″/14″ build. 1-year limited warranty; ships within 72 hours by LTL freight.
Is the FX125 engine reliable?
It can be a reliable first manual dirt bike when it is assembled, broken in, maintained and ridden as intended. Like any gas dirt bike, it needs oil checks, chain care, air-filter service and routine fastener inspection.
Will the FX125 run longer than a few months?
It should not be judged like a disposable toy. Long-term running depends on setup, break-in, maintenance, rider behaviour, terrain and storage. The owner footage on this page covers a summer of hard use, from June delivery to a first track race in late August; the only failure he reported was a kickstand spring, after its mounting bolt worked loose.
How does FRP warranty support work for the FX125?
Contact FRP support with your order information, photos and a clear description of the issue. Warranty support depends on the issue type and on whether the bike was used, maintained and modified within the policy terms.
Does the FX125 come with oil in the engine?
Check before the first start. The owner on this page found almost no oil when he pulled the drain plug on his new bike. Fill with 10W-40 or 10W-50 to the upper dipstick mark, as the manual specifies, and open the fuel valve before pressing the starter.
What comes in the box with the FX125?
The bike, gloves, goggles, anti-fog spray, a backpack with a hydration bladder, a tool kit with carry bag and the user manual. A helmet is not included.
Is the FX125 street legal?
No. It is EPA off-road only, not street legal, and not sold in California. Ride on private property or designated off-road areas with full gear.
The bottom line
The FRP Moto FX125 earns its place as a first real manual trail bike: a true clutch, hydraulic brakes, a 265 lb rider rating and two wheel sizes that fit younger teens through adults — and, as the owner footage above shows, it handled a summer of hard riding and a first race needing nothing more than a kickstand spring. It is not for absolute beginners or street use. For a rider ready to step up, match the wheel size to the rider and gear up.
