The best 12-inch dirt bike rim depends on whether you need a bare wheel component or a complete rear assembly with tire, sprocket, and brake parts. The options below include a wheel for specified 110cc and 125cc bikes, tire-and-wheel assemblies for broader pit-bike use, and a rim hub designed around a 15mm bearing. Check axle size, brake type, sprocket fit, and mounting dimensions before ordering.
| Product | Best for | Key detail to verify |
|---|---|---|
| Complete rear wheel assembly | 125cc–160cc bike owners | Axle and bike fit |
| 12-inch rear wheel rim | 110cc–125cc bikes | Bolt pattern and width |
| EOPOAYI rear rim and tire | Listed 110cc–125cc models | Drum or disc brake setup |
| 12-inch wheel with sprocket and rotor | Complete replacement needs | Axle and brake dimensions |
| Trkimal rear wheel rim hub | 15mm-bearing applications | Tire and hub compatibility |
Complete Rear Wheel For 125cc–160cc Bikes

This complete rear wheel listing specifies an 80/100-12 tire, a 3.00-12 rim, and a 12–15mm axle range. Its title identifies 125cc–160cc TTR, SSR, and mini-motorcycle applications. Choose this if you want a tire-and-wheel assembly rather than a rim alone. The listed axle range makes exact measurement important: confirm the axle and bearing arrangement for your bike before purchase.
12-Inch Rear Rim With Specified Mounting Dimensions

This rear wheel is listed for 110cc and 125cc dirt bikes, including Tao, TTR, SSR, CRF, and Apollo models. The supplied dimensions include 70mm bolt-hole spacing measured center to center, 100mm diagonal spacing, and 53.5mm overall rim width. It is best for buyers who can compare those measurements with their existing wheel. The listing advises checking compatibility; model names alone do not establish a fit.
EOPOAYI 12-Inch Rear Rim And Tire Assembly

EOPOAYI lists this 80/100-12 assembly for models including TaoTao DB14, SSR 110cc and 125cc SR125, and Coolster QG-214. The package description also mentions a 428 41T sprocket, disc brake rotor, and rim strip. It is best for buyers seeking several rear-wheel components together. Important limitation: the listing says some factory drum-brake models will not fit directly unless converted to disc brakes. Confirm brake type and model-year fit before choosing it.
12-Inch Wheel With Sprocket And Brake Rotor

This 80/100-12 rear wheel assembly includes a sprocket and brake disc rotor. The listing gives a 12-inch rim diameter, a 12mm axle-hole diameter, a 19cm rotor diameter, and a stated overall bearing capacity of 140kg. It is best for buyers replacing multiple rear-wheel parts at once and comparing dimensions to an existing setup. Its compatibility examples span several engine sizes, but verify axle, brake, and mounting alignment rather than relying on engine displacement alone.
Trkimal 12-Inch Rear Rim Hub With 15mm Bearing

The Trkimal listing describes a 12-inch wheel rim with a 15mm bearing, steel and aluminum-alloy construction, and fitment for an 80/100-12 rear tire. This is best for buyers who need a rim hub and already know their bearing and tire specifications. It is not described as a complete tire assembly, so check what components are included. Confirm that the bearing size and hub arrangement match the motorcycle before ordering.
Buying Guide: How To Choose A 12-Inch Dirt Bike Rim
Does a 12-inch rim fit every 12-inch dirt bike?
No. “12-inch” describes the wheel diameter, not the complete fit. Axle diameter, bearing size, hub width, brake design, sprocket position, and mounting-hole spacing can differ between bikes. Compare the replacement listing with the original wheel and the motorcycle’s specifications.
Should you buy a rim or a complete rear wheel?
Choose a rim or hub when you intend to reuse compatible parts or need a specific component. Choose a complete wheel assembly when you need the tire and other listed parts, such as a sprocket or rotor. Read the included-parts description carefully; product titles do not always establish every component in the package.
What measurements matter most?
- Measure axle diameter and bearing size.
- Compare hub width and wheel alignment.
- Check sprocket bolt spacing and chain alignment.
- Match the brake type and rotor dimensions.
- Confirm tire size, such as 80/100-12 or 3.00-12.
How does brake type affect compatibility?
A wheel made for a disc brake may not directly replace a drum-brake wheel. The EOPOAYI listing specifically notes that certain drum-brake models require a disc-brake conversion for direct use. Do not assume a conversion is included; verify the motorcycle’s existing brake system and the assembly’s supplied parts.
Frequently Asked Questions
Is an 80/100-12 tire the same as a 3.00-12 tire?
Both sizes appear in the product listings for 12-inch dirt bike wheels, but confirm the tire and rim specifications for your motorcycle before substituting one size for another.
Can I select a wheel by engine size alone?
No. Engine size is only one fitment clue. Axle, hub, brake, sprocket, and mounting dimensions must also match.
What does a 15mm bearing specification mean?
It identifies the stated bearing size for that wheel hub. Check that your axle and wheel arrangement are designed for that bearing specification.
Are these all bare rims?
No. Several listings describe tire-and-wheel assemblies or include parts such as a sprocket and brake rotor. Check the individual listing to establish what is included.
