Rim Tube Tire 80/100-12 12-15mm Rear Wheel
Best for: small wheel, 12″ pit bike setups needing axle versatility. This wheel features an adjustable bearing system with 12 and 15mm bearings, allowing users to match axle size to their machine. The design accommodates Chinese rear rim wheels for 110cc and 125cc dirt bikes, including newer Apollo models. It is important to verify axle hole size and refer to measurements and images to ensure a correct fit. The sprocket and rotor are configured for 428 chain size with a 41T setup and a 187mm rotor outside diameter.
Why chosen: The adjustable bearing system helps users avoid buying multiple wheels for different axle standards, streamlining maintenance on garage‑built or mixed‑brand bikes. This option avoids overcommitting to a single, fixed axle size and supports compatibility across several popular dirt bike platforms.
Better for: Riders who own or service a mixed fleet of 110cc–125cc dirt bikes and want one rear wheel that can adapt to various axle thicknesses. Better for workshop setups where swapping axles is common.
Caution: The axial compatibility depends on precise measurements of your machine’s axle size and rotor mounting. Misalignment can affect brake performance and chain tension if not matched properly.
12” Rear Wheel 80/100-12 Dirt Bike Tire Assembly
Best for: SSR, TaoTao, and Coolster models around 110cc–125cc with disc brakes. This wheel assembly is marketed with a 428 chain and 41T sprocket and comes as a complete unit with brake rotor, making it convenient for riders replacing worn components in one package. It carries the XIKOBY Store branding, reflecting a focus on fitment for common Chinese 125cc dirt bikes.
Why chosen: The included rotor and sprocket provide a straightforward upgrade path for riders seeking better chain grip and reliable braking on disc‑equipped machines. The wheel is described as knobby‑tread designed for traction on rough trails, mud, and loose dirt, aligning with off‑road needs.
Better for: Riders who want a ready‑to‑install rear wheel with brake rotor, suitable for direct bolt‑in swaps on compatible models. Good for those who prefer a single purchase that covers wheel and drivetrain interface.
Caution: Compatibility is model‑dependent, particularly for drum vs disc brake systems. Verify brake type and rotor compatibility with your bike before purchase.
14″ Rear Wheel Rim Tire Assembly 90/100-14
Best for: 125cc–160cc pit bikes and trail bikes like KLX65, Apollo, Kayo, TT125, and other models that use a 90/100-14 tire. The wheel assembly includes a brake rotor and sprocket, designed to align with a 15mm axle, a 187mm rotor, and a 428‑41T sprocket. It emphasizes durability through a high‑quality alloy rim, 32 spokes, and 6202RS bearings to withstand rugged off‑road use.
Why chosen: This option provides a broad fit for a common 14″ rear wheel standard, enabling riders to upgrade to a more robust wheel with integrated braking and drivetrain components. It addresses stability and power transfer over rough terrain, a frequent requirement for trail riders.
Better for: Riders seeking a reliable, all‑in‑one rear wheel replacement for 125cc–160cc bikes with 14″ wheels and drum or disc options depending on model configuration.
Caution: Ensure your brake system (drum vs disc) and hub alignment match the rotor and sprocket included in this assembly. Incompatible brake types may require additional adapters or parts.
14 Inch Rear Wheel 90/100-14 Assembly
Best for: Off‑road riders seeking a widely compatible 14″ wheel with brake rotor and sprocket included for typical 125cc–160cc bikes. This assembly is marketed to support common brands and riders who prefer a straightforward in‑shop swap.

Better for: Riders upgrading to 14″ wheels on a range of pit bikes and trail bikes who want a dependable, all‑in‑one kit for improved traction and stopping power.
Caution: Double‑check hub spacing and rotor compatibility with your specific model, as some bikes may require adapters for optimal braking performance.
Buying Guide
Key questions to consider when choosing a rear dirt bike wheel:
- What is my bike’s wheel size and brake type (drum vs disc) and does the wheel include the rotor if needed?
- Does the axle size on my bike match the wheel’s adjustable or fixed bearing system (12/15mm options are common)?
- Is the wheel compatible with my sprocket and chain size (for example, 428 chain with 41T sprocket is a common standard)?
- Do I need a complete assembly (wheel, rotor, sprocket) or just the rim and tire?
- What riding conditions are most common (mud, loose dirt, rocky trails) and which tread and wheel width suit those terrains?
FAQ
- What wheel size fits most 110cc–125cc dirt bikes?
Most popular sizes are 12″ and 14″ wheels with 80/100-12 or 90/100-14 tires, depending on model and brake type. - Do front and rear wheels share the same axle dimensions?
Not always; rear wheels often require specific axle sizes (e.g., 12mm or 15mm). Check your bike’s rear hub specs. - Is it okay to mix wheel brands?
It’s possible if dimensions, bolt patterns, sprockets, and rotors align; otherwise, it can affect braking and drivetrain performance. - Should I replace the rotor and sprocket with the wheel assembly?
If included, it simplifies installation and ensures compatibility; otherwise verify mounting interfaces. - Can I install a 14″ wheel on a 125cc pit bike not originally designed for it?
Only if the frame clearance, chain tension, and brake system accommodate the larger wheel. Check model‑specific guidance. - What maintenance helps prolong wheel life?
Regularly inspect spokes, bearings, rotor runout, and hub seals. Keep tires inflated to recommended pressures for best grip and control.
