The best 12-inch pit bike rear wheel depends on your axle diameter, brake setup, tire size, and sprocket requirements. The XIKOBY and EOPOAYI assemblies offer listed model fitment and disc-brake components; the adjustable-bearing wheel is worth considering when axle size is the main concern. Other options specify a 12mm axle or wheel mounting measurements, so check your existing parts before choosing.
| Product | Best For | Key Check |
|---|---|---|
| XIKOBY 12-inch assembly | Listed models with disc brakes | Drum-brake bikes need conversion |
| Adjustable-bearing complete wheel | 12mm or 15mm axle applications | Confirm axle and mounting fit |
| 80/100-12 disc wheel assembly | Buyers matching wheel dimensions | 70mm rotor, 65mm sprocket spacing |
| 12mm axle wheel assembly | Compatible 12mm axle bikes | Not for 15mm axles |
| EOPOAYI rear wheel assembly | Listed SSR and TaoTao models | Disc-brake fitment required |
XIKOBY 12-Inch Rear Wheel Assembly
This complete assembly includes an 80/100-12 tire, inner tube, brake rotor, and 428 41T sprocket. The product listing names SSR 125cc SR125, TaoTao DB14, Coolster QG-214, and select CX65 and KTM 65 models as compatible applications. Its knobby tread is described for varied off-road terrain, while the steel sprocket is heat-treated and designed to resist corrosion.
Best for: Riders with a listed model that already uses a compatible rear disc-brake setup. It was selected for its included tire, tube, rotor, and sprocket, plus specific model-fitment information. The listing cautions that several other bikes with drum brakes are not direct fits unless converted to disc brakes. Verify your exact model and brake configuration before ordering.
Adjustable-Bearing 12-Inch Complete Wheel
This 80/100-12 wheel assembly includes 12mm and 15mm bearings that can be changed to suit the required rear axle size. The listed sprocket has 41 teeth for a 428 chain, and the rotor measures 187mm in outside diameter. The stated axle-hole range is 12–15mm. The listing mentions applications including 110cc and 125cc dirt bikes and some newer Apollo bikes.
Best for: Buyers whose main fitment question is whether the wheel can accommodate a 12mm or 15mm axle. It stands out for its changeable bearing setup and stated rotor and sprocket specifications. The listing advises checking axle-hole size and using measurements and pictures to confirm fit, so do not rely on engine size or brand alone.
80/100-12 Disc-Brake Wheel Rim Assembly
This listing describes an 80/100-12 complete rear wheel rim assembly for a dirt bike. Its stated disc mounting distance is 70mm, and its sprocket mounting distance is 65mm. The available product details do not specify a model-by-model fitment list or provide additional tire, axle, or sprocket information.
Best for: Buyers who can compare their existing wheel’s mounting dimensions with the listed 70mm disc and 65mm sprocket distances. It was selected as a dimension-focused option for shoppers who already know their bike’s requirements. Confirm axle diameter, tire inclusion, and other mounting measurements with the seller or product details before purchase, since they are not specified in the supplied listing information.
12mm Axle Wheel With Rotor and Sprocket
This 12-inch rear wheel assembly is designed for an 80/100-12 or 3.00-12 tire and includes a disc brake and 428 41T chain sprocket. The listing describes it as an upgrade option for select 50cc–125cc Apollo, SSR, XR, and CRF dirt bikes. It explicitly identifies a 12mm axle.
Best for: Riders who have verified that their bike uses a 12mm rear axle and need the listed rotor and sprocket included. It was selected for its clear axle-size warning and bundled components. Avoid this if your bike uses a 15mm axle; the listing says this wheel will not work with 15mm axles. Confirm the exact model and brake arrangement as well.
EOPOAYI 12-Inch Rear Rim and Tire
The EOPOAYI assembly uses an 80/100-12, also identified as 3.00-12, knobby tire. Its listed fitment includes TaoTao DB14, SSR 110cc and 125cc SR125, Coolster QG-214, and select CX65 models. The assembly includes a 428 41T steel sprocket and disc rotor. The listing also describes a rim strip intended to cover spoke holes and rim seams.
Best for: Riders with a listed model and compatible disc-brake configuration who want the tire, rim, rotor, and sprocket together. The product was selected for its fitment details and included rim strip. Several named models use drum brakes from the factory, according to the listing, and this assembly will not fit those directly without converting to disc brakes.
Buying Guide: How to Choose a 12-Inch Pit Bike Rear Wheel
Which axle diameter does your bike use?
Measure the rear axle or check the bike’s specifications before selecting a wheel. The products here differ: one offers 12mm and 15mm bearing options, while another is specifically for a 12mm axle and excludes 15mm axles. A wheel that matches the tire size can still be incompatible if the axle or bearing setup is wrong.
Does your bike use a disc or drum brake?
Check the rear brake type and rotor mounting before ordering. Some listings explicitly state that their disc-brake wheel is not a direct fit for certain drum-brake models. A brake conversion may be required, so do not assume a shared tire size means the brake components will fit.
Are the tire and drivetrain specifications a match?
Compare the current tire size with 80/100-12 or 3.00-12, then verify the chain size and sprocket tooth count. Several options list a 428 chain and 41-tooth sprocket, but not every listing supplies the same details. Check rotor diameter and mounting distances where available, and compare them with your existing parts.
How should you verify model fitment?
Use the exact make, model, year, axle size, brake type, and mounting measurements. Product listings may name compatible bikes while excluding versions with different factory brakes. When a listing provides limited fitment information, contact the seller or compare the wheel measurements before buying rather than relying only on engine displacement.
Frequently Asked Questions
What tire size fits these 12-inch rear wheels?
The products described here are listed for 80/100-12 tires, also called 3.00-12 in several product names. Confirm the tire size on your bike and the wheel’s specifications before ordering.
Can a 12-inch wheel fit any pit bike with a 12-inch tire?
No. Axle diameter, bearings, brake type, rotor mounting, and sprocket alignment also affect fitment. Check these details against the specific product listing.
Can I use a disc-brake wheel on a drum-brake bike?
Not necessarily. Some listings say the wheel is not a direct fit on named drum-brake models unless the bike is converted to a disc-brake setup.
What does 428 41T mean?
In these listings, 428 identifies the chain size and 41T identifies a 41-tooth sprocket. Verify that both match your bike’s existing drivetrain requirements.
Is a 12mm axle wheel compatible with a 15mm axle?
Not always. One listed assembly expressly says it will not work with 15mm axles. Choose a wheel and bearing configuration that matches your measured axle size.
