Front Tire and Wheel Kit With 70/100-19 & 90/100-16
Best for riders seeking a complete front and rear tire solution for big-wheel dirt bikes. The kit specifies a 70/100-19 front with a 1.6*19 rim and a 90/100-16 rear on a 1.85*16 rim, both with 15mm bearing compatibility. It includes fork and shock measurements that help confirm proper fit on Pit and Trail bikes. Choose this if you need a single-source upgrade for both wheels and you ride on mixed terrain.
Who it’s best for: riders upgrading a motocross or pit bike to larger wheels, aiming for improved ground clearance and traction. Caution: verify mounting distances (56mm) and fork leg dimensions (45mm/48mm) against your bike’s specs to avoid misfit.
3.00-14 & 90/100-14 Rear Wheel Set with 15mm Bearing
Best for riders needing a versatile wheel pair with strong compatibility across several 110cc–160cc dirt bikes. The kit is designed for off-road use and mud-friendly performance, featuring a 15mm bearing option and a robust aluminum build. Choose this if you want broad model compatibility and a lightweight aluminum wheel. Limitation: specific model compatibility should be confirmed before ordering.
14″ / 12″ Wheels Kit with 15mm Bearing
Best for budget-minded riders looking for a simple upgrade with strong grip and easy installation. The kit emphasizes durable construction, enhanced tire grip due to concave/convex surface design, and a loading capacity near 441 lbs. Choose this if you want a straightforward, safe upgrade without premium pricing. Caution: verify axle and mounting distances (15mm bearing, 70mm disc spacing) for your bike’s setup.
38 PCS Tire Spoons Tool Set
Best for DIY tire maintenance and frequent wheel work. This complete 38-piece toolkit includes tire irons, rim protectors, valve tools, and a storage bag, plus hardened-steel levers for durability. Choose this if you routinely service dirt-bike tires and need a full set of tools. Limitation: tools alone don’t provide a wheel upgrade; pairing with proper wheels and tires is necessary.
Dirt Bike Training Wheels For 49cc–50cc Models
Best for beginner riders seeking stability and safety. These training wheels are designed for universal fit on most 49cc–50cc dirt bikes, with adjustable height to accommodate skill level and terrain. Choose this if you want to reduce fall risk during early rides. Caution: training wheels do not upgrade wheel size or suspension performance.
Buying Guide: Key Considerations For Dirt Bike Big Wheel Upgrades
- Compatibility: Check diameter, width, bearing size (15mm bearings are common in these kits), and axle hole spacing to match your bike’s model and year.
- Intended Terrain: Consider your riding environments—mud, rocky trails, or sandy areas—and select tires with appropriate tread patterns and sidewall strength.
- Weight and Material: Aluminum rims are lighter and resistant to corrosion but verify impact resistance for your riding style and weight load.
- Installation Simplicity: Some kits include integrated mounting distances and fork/shock measurements to ease installation; others may require adapters or professional setup.
- Overall Budget: A combination of wheels, tires, and tools can vary widely; balance cost with durability and fit for long-term use.
