YC Yier Front Forks + Rear SwingArm Kit 14″ 12″ Complete Wheel
Best for riders seeking a full upgrade package in one purchase. This kit combines front forks and a swingarm with a complete wheel setup, including 60/100-14 front and 80/100-12 rear tires. It aligns with 14″ front and 12″ rear configurations, making it ideal for mid-sized pit bikes and small-displacement dirt bikes. The package lists a 70mm fork mount and 65mm sprocket mounting distances for compatibility with common off-road builds. A limitation is that precise fit may vary by model; verify axle sizing before purchase.
ICONSPORTSS Front Fork & Rear Swingarm Kit with 14″ Front / 12″ Rear Wheels
Best for riders who want a robust, all-in-one upgrade that emphasizes off-road traction. The kit includes front forks, rear swingarm, and knobby tires (60/100-14 front, 80/100-12 rear) on 1.40×14 and 1.85×12 rims, respectively. It offers a complete suspension and wheel upgrade suitable for 50cc–140cc dirt pit bikes. The front fork length is 28.94 inches, designed to fit 14″ to 17″ wheels with standard clamp sizes. This selection is better for aggressive terrain and may feel stiffer on smooth surfaces.
YC Yier 14″ Rear Wheel Rim Tire Assembly Upgrade Swingarm Kit
Best for riders who want a focused rear-end enhancement with everything needed for a pit bike upgrade. This kit includes a 14″ rear wheel assembly with a 1.85×14 rim and a 90/100-14 knobby tire, inner tube, wheel bearing, disc rotor, and sprocket plus a swingarm, brake caliper, 420 chain, and shock. It is well-suited for Apollo SSR, Taotao, CRF, and other common pit bike brands. A potential limitation is wheel compatibility with certain frames—double-check brake caliper mounting and disc alignment before installing.
80/100-12 Rear Wheel Kit with Swingarm and Disc Brake (15mm Axle)
Best for budget-minded buyers needing a complete rear-wheel upgrade. This kit features an 80/100-12 tire on a 1.85×12 rim, a heavy-duty swingarm, and a 15mm axle, designed for CRF70, CRF50, XR70, SSR, Taotao, and similar dirt pit bikes. It improves traction and stability on rough terrain. A note: ensure compatibility with your frame’s brake mounting and chain alignment, as some frames may require additional adapters.
YunGlee Swingarm Extension Kit
Best for riders seeking a longer wheelbase to improve straight-line stability on loose terrain. The kit includes two swingarm extension brackets and installation bolts (rear wheel, axle, and chain not included). It is specifically designed to work with 2023–2026 Coleman B200RSV models but can be adaptable to other bikes with similar frame geometry. A limitation is the need to verify model-year compatibility before purchasing to avoid fit issues.
Buying Guide: Key Considerations And Comparisons
- Fitment and compatibility: Always verify wheel size (14″ front vs 12″ rear, or other combinations) and axle diameter (commonly 15mm) for your specific bike model.
- Intended riding style: Heavy-duty, knobby tires excel off-road traction, while lighter kits suit casual trail riding and street-able pit bikes.
- Complete vs partial kits: Full front-and-rear upgrades save time and ensure balanced handling; rear-wheel-only kits are often simpler and cheaper.
- Brake and sprocket alignment: Check disc rotor, caliper mounting, and sprocket spacing to prevent alignment issues after installation.
- Durability vs budget: Higher-budget kits typically offer stronger swingarms and better wheel components; consider your terrain and riding intensity.
- Documentation and support: Look for clear installation instructions and compatibility notes to minimize trial-and-error.
Frequently Asked Questions
- What is a swingarm kit?
It typically includes a new swingarm, sometimes wheels, tires, brakes, and sprockets to upgrade rear suspension and traction. - Will these kits fit my pit bike?
Most kits target common pit-bike sizes (12″ rear, 14″ front). Always confirm wheel diameter, axle size, and brake compatibility with your model. - Do I need professional installation?
Given brake alignment, chain tension, and suspension mounting, professional installation is recommended for safety and performance gains. - Are knobby tires required for off-road riding?
Knobby tires provide superior traction on dirt and loose surfaces, but may wear faster on pavement. - Can I mix parts from different kits?
Mixing components is possible but requires careful measurement and alignment checks to avoid interference or unsafe fitment.
