Fuerduo Front + Rear Wheels Set
This full wheel set includes both front and rear wheels tailored for dirt pit bikes, featuring rims, inner tubes, and bearings. The rear tire is 90/100-14 paired with a 2.75×14 rim, while the front adopts a 70/100-17 combination. The setup is designed for off-road performance with aggressive knobs for dirt trails. Bearings are included to streamline installation, and both wheels are positioned to maximize grip and stability on intermediate to hard terrain.
Selecting this bundle is ideal for riders seeking a consolidated upgrade with balanced front and rear performance. Ensure the rims and tire sizes match the bike’s frame clearance and suspension geometry, and verify rotor and sprocket compatibility if you plan to reuse existing components.
Buying Guide: Key Purchase Considerations
- Wheel size and compatibility: Common pit bike rear wheels come in 12″ and 14″ sizes, with tires such as 80/100-12, 90/100-14, and 70/100-17. Verify that the wheel size matches your bike’s frame, swingarm clearance, and fender geometry.
- Axle hole and bearing size: Axle hole diameters commonly range from 12mm to 15mm. Check your hub’s axle size and bearing type (often 15mm) to avoid misfits. Some listings note 12mm or 15mm bearings; ensure the kit matches your bike’s spec.
- Rotor and sprocket compatibility: Many rear wheel kits include a brake rotor and sprocket. Confirm mounting distances (disc mount and sprocket spacing) so you don’t need to modify hubs or adapters.
- Brake type and rotor fit: Disk brake configurations demand compatible rotor mounting patterns and caliper clearances. If your bike uses a drum brake or a different rotor pattern, ensure the kit aligns with your braking system.
- Quality and materials: Look for reinforced tire sidewalls, wear-resistant rubber, and sturdy rims. Explosion-proof or reinforced tires can reduce blowouts on rough tracks, while durable rims help resist dents and bends during hard landings.
- Brand and model compatibility: Listings often mention compatible makes (Apollo, Kayo, KLX, TTR, SSR, etc.). Cross-check the exact model and year of your bike to avoid misfit.
- Installation effort: Some sets are “ready-to-install” with rotor and sprocket, while others may require transferring components. If you’re upgrading multiple parts (bearings, sprockets, rotors), plan for a slightly longer installation.
- Maintenance considerations: Inspect bearings for wear, confirm seals are intact, and check tire tread age. Regular lubrication and torque checks help maintain performance and safety on dirt surfaces.
