HIAORS 60-Tooth #35 Rear Sprocket for Mini Bike Go-Kart Trike — 2" Center, Heavy-Gauge Steel, 7-1/4" OD

HIAORS 60-tooth #35 rear sprocket — a heavy-gauge steel replacement designed to fit mini bikes, go-karts, trikes and ATVs using #35 chain and a four-bolt 2" center pattern.

If you need a durable, correctly sized sprocket for a Predator 79cc, Predator 212cc, 420cc engine or other small-vehicle drivetrains, this HIAORS unit gives you the measured dimensions and mounting pattern technicians look for. Built from heavy-gauge steel with a 7-1/4" outside diameter and a standard four-bolt layout, it replaces worn or damaged rear sprockets for smoother power transfer and longer service life.

How do I confirm this sprocket will fit my mini bike or go-kart?

Measure the old sprocket or the hub mounting: this model requires a 2" center hole and a four-bolt mounting pattern with 3/8" diameter bolts. Count the teeth on your current sprocket — you need a 60-tooth unit for the same final drive ratio.

• Center hole diameter: 2"
• Overall diameter (OD): 7-1/4"
• Mounting holes: 4 with 3/8" diameter
• Mount hole spacing (across): 2-7/8", side-by-side: 2-1/16"

What materials and construction features affect durability?

This sprocket is stamped from heavy-gauge steel for resistance to wear, bending and impact common in off-road and recreational use. The robust construction helps maintain tooth profile and chain engagement under load, reducing the frequency of replacement compared with thin or soft metal alternatives.

• Heavy-gauge steel body for longer life
• Precision-cut teeth to match #35 chain pitch
• Industry-standard four-bolt pattern for secure mounting

Which engines and applications is this sprocket compatible with?

It’s commonly used on mini bikes, go-karts, trikes and small ATVs that run Predator 79cc, Predator 212cc and various 420cc setups, but it also works with any application matching the specified dimensions. Always cross-check your machine’s sprocket tooth count, chain size (#35) and bolt pattern before ordering.

• Common fit: Predator 79cc and 212cc engines
• Also compatible with many 420cc small-engine drivetrains
• Usable on mini bikes, go-karts, trikes and quads when dimensions match

How should I inspect and replace the sprocket for best results?

Before installation, inspect your chain and hub for wear: replacing a worn chain with a new sprocket extends service life. Torque mounting bolts to the vehicle manufacturer’s specification and recheck alignment and chain tension after a short break-in ride.

• Inspect chain for stretch and damaged rollers
• Clean mounting surface and remove burrs before fitting
• Use proper torque and re-inspect chain tension after 10–20 miles

Who is this for: Mechanics, hobbyists and riders who maintain mini bikes, go-karts, trikes or small ATVs and need a reliable replacement sprocket with precise dimensions will appreciate this HIAORS 60-tooth #35 rear sprocket. It’s aimed at users who can verify measurements and perform or supervise a sprocket swap, and anyone seeking a heavy-gauge steel part to handle recreational and utility use without frequent replacement.
