YOXUFA Go Kart Sprocket Hub 1" Bore 60T Rear Drive — 420/41/40 Chain Compatible, Steel Heavy-Duty

Heavy-duty 60-tooth sprocket hub assembly with a 1" bore and 1/4" keyway designed to fit most Predator 212cc/196cc 6.5hp mini bikes, go karts, trikes and dune buggies using #40/41/420 chain.

This complete rear drive kit from YOXUFA combines a robust 4" sprocket hub, a 420-compatible 60T sprocket and the mounting hardware you need to swap or replace worn drivetrain parts quickly. Built from steel for strength and longevity, the assembly is engineered for applications using 1" live axles with a 1/4" keyway — a common spec on many small-engine recreational vehicles. Before purchasing, confirm your wheel hub center hole, bolt circle, and live axle size match the dimensions below to ensure proper fitment.

Will this sprocket hub fit my Predator 212cc or 196cc go kart?

Compatibility depends on several measurements rather than engine brand alone. The YOXUFA hub is intended for 1" live axles with a 1/4" keyway and mounts to sprockets with a specific bolt circle and center hole diameter.

• Hub bore: 1" (25.4 mm) with 1/4" keyway
• Overall sprocket outer diameter: 248 mm (9.76")
• Center hole (sprocket): 54 mm (2.13") and bolt circle: 90 mm (3.54")
• Thickness: 6 mm; 8 mounting holes (10 mm each)

How durable is the YOXUFA sprocket hub for heavy use?

The assembly is manufactured from steel to resist wear from chain tension and off-road stress. The 60-tooth sprocket and solid hub design distribute load across multiple mounting points to reduce fatigue under repeated acceleration and braking.

• Steel construction for strength and rust resistance with proper maintenance
• 8 mounting holes spread load evenly across the bolt circle
• 6 mm sprocket thickness to withstand chain torque
• Includes hardware and 1/4" key for secure axle engagement

What comes in the box and what tools will I need?

YOXUFA ships a ready-to-install package that includes the sprocket, hub and necessary fasteners so you won’t need to source extras. Basic hand tools for removal and installation of axle keys, nuts and bolts are typically all that’s required.

• Included: 1 x sprocket hub, 1 x 420-60T sprocket, 1 x 1/4" keyway
• Included hardware: 4 screws and 4 nuts for initial assembly
• Suggested tools: socket set, torque wrench, hex keys and thread locker
• Tip: verify bolt torque and chain alignment after installation

Can I use this hub with different chain sizes?

The sprocket is drilled and profiled for #40, #41 and 420 chain standards, so it will accept any of these compatible chains. Always match chain pitch and width to the sprocket profile for smooth operation and longer life.

• Compatible chain types: #40, #41, 420
• 60-tooth profile sized for light-duty and mid-range torque loads
• Check chain tension and alignment to avoid premature wear
• Not compatible with oversized industrial chains outside listed specs

Who is this for: This YOXUFA sprocket hub assembly is aimed at DIY mechanics, racers and recreational riders who maintain or upgrade small-engine go karts, mini bikes, drift trikes and light dune buggies. It’s ideal if you need a direct replacement for a 1" live axle with a 1/4" keyway and a 420-compatible 60T sprocket, and for anyone seeking a straightforward hardware kit that includes the sprocket, hub and mounting parts for a rapid swap.
