RedCap 12-Inch Rear Wheel Assembly
The RedCap wheel assembly is designed for 110cc and 125cc dirt pit bikes, including Apollo and SSR models. It features a 15mm axle hole for precise fitment and dependable rear wheel alignment. Best for riders seeking a ready-to-mount option with included brake rotor and 428 sprocket, suitable for those who want a straightforward upgrade without sourcing parts separately.
Best for: riders who value a complete kit with rotor and sprocket for quick installation on common pit bike platforms.
Caution: confirm your bike’s axle sizing and brake type before purchase, as some models may require an alternative rotor or sprocket fitment.
XIKOBY 12″ Rear Wheel Assembly (SSR/TaoTao/Coolster)
The XIKOBY option pairs an 80/100-12 tire with a 3.00-12 rim and includes a brake rotor and 428 41T chain sprocket. It is designed for direct fit with SSR SR125, TaoTao DB14, Coolster QG-214, CX65 and related dirt bikes, including models with 15mm axle setups. Best for: riders seeking broad compatibility and a rugged, knobby-tread rear wheel that performs across varied off-road terrains.
Limitation: some bikes with drum brakes may require upgrading to a disc brake system to utilize the rotor provided.
XIKOBY 12″ Rear Wheel Assembly (Alternative)
This variant mirrors the 80/100-12 size with a focus on a nylon wheel body for wear resistance and shock absorption. It includes a nodular-tread tire and a high-strength aluminum rotor with a steel sprocket, designed to deliver strong traction and smoother chain wear. Best for: riders who prefer a lighter wheel assembly with robust rotor and sprocket hardware for off-road endurance.
Caution: verify your bike’s brake configuration since some models require a drum-to-disc conversion to use the included rotor.
aohuang 12″ Rear Wheel Rim
The aohuang rear wheel rim is designed for 110cc and 125cc dirt bikes with a 15mm axle style and specific bolt hole spacing. It lists precise measurements (center-to-center and diagonal spacing) to help buyers confirm compatibility before purchasing. Best for: riders who know their bike’s exact bolt pattern and want a rim with dependable fitment for 12-inch wheels.
Limitation: exact compatibility must be verified against your bike’s brake type and axle configuration to ensure a clean install.
Buying Guide
What should I look for in a 12-inch dirt bike rear wheel?
Key factors include tire size compatibility (80/100-12 is common for 12-inch setups), axle hole size (often 15mm), brake compatibility (disc vs. drum), and the availability of a complete kit (rotor and sprocket) for easier installation.
Which wheel is best for a specific bike model?
South-to-north cross-compatibility ranges from XR/CRF-style pit bikes to TaoTao and SSR variants. If your bike uses a 15mm axle and a disc brake, prioritize wheels advertised with a disc brake rotor and 428 sprocket. If your bike uses a drum brake, verify if the rotor can be used or if a drum-compatible option is available.
What are the durability considerations?
Look for wheels with robust spokes, quality bearings, and a reinforced rim. Nylon body or aluminum rotor options can influence weight, heat dissipation, and resistance to impact on rough terrain.
Do I need to replace other parts?
Often, replacing a wheel also requires compatible sprockets and rotors. Ensure the sprocket teeth count matches your chain length and that the rotor mounting matches your bike’s hub pattern.
What installation steps are typical?
Steps usually include removing the old wheel, installing the new wheel on the swingarm, aligning the sprocket with the chain, securing the axle with correctly torqued nuts, and verifying brake operation. If upgrading to a disc brake, ensure the caliper, rotor, and mounting hardware align with the bike’s frame and fork design.
What risk factors should I consider?
Improper fitment can cause wheel misalignment, accelerated wear, or brake interference. Always confirm model-year compatibility and measure bolt patterns and axle dimensions before ordering.
FAQ
- Q: Do these wheels fit all 12-inch dirt bikes? A: They target common 12-inch rear wheel setups for 110cc to 125cc pit bikes, XR/CRF-style bikes, and similar models, but verify axle size, brake type, and bolt pattern for your exact model.
- Q: Is a disc brake rotor included with every wheel? A: Most listings include a rotor and 428 sprocket, but confirm the exact components in your chosen package.
- Q: Can I install these without professional help? A: Yes, for straightforward installations, but ensure you have the right tools and torque specs. If upgrading brakes, seek professional alignment checks.
- Q: Will upgrading the wheel affect chain tension? A: Yes. After wheel swap, re-tension the chain to manufacturer guidance and inspect for wear on the sprocket and chain.
- Q: How can I confirm fitment before purchase? A: Compare axle hole size, bolt pattern, brake type, and tire size with your bike’s specifications; many listings provide model compatibility and dimension notes.
- Q: Are there any cautions about materials? A: Some wheels use nylon bodies or aluminum rotors; assess weight, impact resistance, and heat handling for your riding conditions.
