FVRITO Rear Wheel Assembly for Razor MX500 MX650 SX500 — 2.50-10 Tyre, 140mm Disc & Sprocket

FVRITO’s MX650 rear wheel assembly is a complete, ready-to-install replacement rear wheel for Razor MX500, MX650 and SX500 mini dirt rocket bikes, featuring a 2.50-10 tire/tube, 140mm disc rotor and integrated sprocket and axle.

When a worn or damaged rear wheel leaves your mini dirt bike sidelined, swapping the whole assembly is faster and more reliable than patching tires or rebuilding parts. This FVRITO unit arrives pre-mounted with a knobby off-road tire, tube, rim, chain sprocket and brake rotor so you can restore rideability in a single replacement. The assembly is designed to match the original OEM fitment and supports typical off-road loads for these Razor models.

Will this rear wheel fit my Razor MX500, MX650 or SX500?

Yes — the assembly matches the factory specifications used on MX500, MX650 and SX500 mini dirt rocket bikes. It uses a 2.50-10 tire/tube size and the standard axle dimensions for these models, so it installs without frame modifications.

• Tire/tube size: 2.50-10 with TR87 angled valve stem
• Disc rotor: 140 mm diameter
• Designed as OEM-style replacement for rear use only

How durable is the FVRITO rear wheel for off-road riding?

The wheel is built from materials chosen for abrasion resistance and shock absorption, helping it stand up to rough terrain and repeated use. The knobby tread increases traction in loose surfaces, while the integrated rim and sprocket reduce potential points of failure compared with piecemeal repairs.

• Knobby pattern for higher ground contact and anti-slip performance
• Reinforced rim and tube for improved wear resistance
• Integrated sprocket and rotor minimize alignment issues

How easy is it to replace my old wheel with this assembly?

Replacing the entire rear wheel assembly is straightforward and saves time versus changing a tire, tube, sprocket, and rotor separately. Remove the old assembly and drop in the new FVRITO unit; axle, valve cap and hardware are included to simplify installation.

• Comes with axle and red valve stem cap for one-step swap
• No need to bead tires or press bearings during installation
• Factory-style fitment reduces the need for adjustments

What load and pressure specs should I follow?

Observe the assembly’s rated limits and inflation range to keep handling predictable and components long-lived. The wheel supports typical rider weights for mini dirt bikes and should be inflated to the recommended pressure.

• Maximum load: 275 lbs (125 kg)
• Recommended max tire pressure: 36 PSI
• Valve type: TR87 angled stem for easy access

Who is this for: The FVRITO MX650 rear wheel assembly is aimed at owners of Razor MX500, MX650 and SX500 mini dirt rocket bikes who want a quick, OEM-style rear wheel replacement. It suits riders who prefer restoring functionality fast—mechanics, parents repairing kids’ bikes, or enthusiasts maintaining a spare on hand. Choose this complete assembly if you want a direct-fit, durable wheel with integrated rotor and sprocket instead of sourcing multiple separate parts.
