Minho 12mm 220mm Rear Axle With Bush

The Minho rear axle measures 12mm in diameter and 220mm in length, and it includes three bushes for a secure fit. Built from high-strength steel alloy, this axle balances rigidity with resilience for off-road riding. With a weight around 325g, it provides a robust option for riders seeking a direct replacement that supports rear wheel alignment and smooth operation across 110cc to 160cc pit bikes and mini quads. The included bushes help center the axle and reduce play in the rear hub assembly.
12mm 210mm Front Rear Axle With Bushing

This 12mm axle spans 210mm and includes a 5mm to 30mm bushing range to fit various models. Made from high-strength steel alloy, the axle is designed for durability and consistent alignment in pit dirt bikes and mini dirt bikes. The product emphasizes reliable performance after extensive safety testing and is suitable for 70cc–125cc pit bikes, CRF50-style clones, and related small-displacement machines. This option focuses on stability and an easy swap for riders upgrading worn axles or repairing damaged hubs.
Greesp 15mm Front Rear Wheel Axle

The Greesp axle features a 15mm diameter with a 245mm length, designed for front and rear wheel applications on pit bikes and small motorcycles. This axle suits 110cc–160cc models and is presented as a front or rear wheel axle solution for 125cc to 160cc dirt bikes, including Thumpstar and similar chassis. The longer length supports broader hub spacing and may require additional spacers. Durability is built into the steel construction for consistent wheel alignment and reliability during rugged riding conditions.
YLQYYH 12-15MM Rear Axle with Rim Wheel

This package combines a rear axle compatible with 12–15mm bearings and a complete rim wheel system, including a brake rotor and sprocket. It is intended for 110cc–160cc dirt bikes and is compatible with various makes including newer Apollo dirt bikes. The design emphasizes adaptability; users should verify axle hole sizes and measure thoroughly to ensure a proper fit. The included wheel assembly supports quick swaps and reduces downtime when upgrading to a more robust rear wheel option for trail and pit riding.
Buying Guide: Key Purchase Considerations
- Axle diameter and length: Ensure the axle fits your hub spacing and alignment requirements. Common diameters are 12mm and 15mm, but some models may need a specific length around 210–260mm.
- Bearings and compatibility: Some axles ship with adjustable bearing sizes (e.g., 12–15mm) to fit multiple models. Confirm the bearing size your hub uses before purchasing.
- Material and durability: Look for high-strength steel alloys or heat-treated steels to withstand off-road stresses and reduce the risk of bending or fatigue.
- Included hardware: Some rear axles come with bushes, spacers, rotors, or sprockets. Verify what’s included so you know if you need additional parts.
- Model compatibility: Cross-check your bike’s make and model (Apollo, TTR, SSR, BBR, etc.) and verify that the axle length and hole diameter match your-frame and wheel hub.
- Ease of installation: Axles with clear measurements and compatible bushings simplify the replacement process and reduce the risk of misalignment.
- Spare parts availability: For popular clones, ensure there is reasonable availability of spacers, sprockets, and rotors if you need future maintenance.
Comparison Snapshot
- Best value: YLQYYH rear wheel assemblies offer a complete wheel with rotor and sprocket, suitable for quick upgrades on multiple 110cc–160cc bikes.
- Most adjustable: Axles with 12–15mm bearings provide flexibility across a range of bikes but require careful measurement to avoid mismatch.
- Durability focus: Minho and SIPARTS products emphasize sturdy steel alloys and bushings to reduce play and improve stability during riding.
- Fit variety: 15mm axles like the Greesp option fit a broad set of pit bikes; verify exact hub spacing and threaded area for proper installation.
- Complete kits: Some listings include brake rotors and sprockets, reducing the need for separate parts during upgrades.
