KRGUOD Centrifugal Clutch for Go-Kart & Minibike 3/4" Bore 10T — Fits Predator 212, Up to 6.5 HP, #40/#41/#420 Chain

KRGUOD 3/4" bore centrifugal clutch with 10 teeth delivers smooth, automatic engagement for small engines up to 6.5 HP, compatible with #40, #41 and #420 chains.

This replacement clutch is engineered for go-karts, minibikes and small utility machines that use a 3/4" crankshaft with a 3/16" keyway. Built from impact- and wear-resistant steel, the unit is intended for common 2–6.5 HP engines including Predator 212 and many Honda clone models. The package includes the clutch, mounting bolt, washer kit and a wrench so you can fit it quickly and check alignment before first use.

How does this clutch improve acceleration and drivability?

The centrifugal design engages progressively as engine RPM rises, so power transfer starts smoothly rather than abruptly. That reduces load shock on the chain and drivetrain while providing predictable takeoff behavior for recreational and light-duty racing applications.

• Smooth automatic engagement at rising RPM
• 10-tooth sprocket compatible with #40/#41/#420 chains
• Reduces jerking and drivetrain stress on acceleration

Which engines and vehicles will this clutch fit?

This clutch fits engines with a 3/4" crankshaft and a 3/16" keyway, a common configuration on Predator 212 and many 5.5–6.5 HP clone engines. It’s commonly used on go-karts, mini bikes and small utility machines that call for a 10-tooth sprocket engagement.

• Compatible with Predator 212 and many Honda-clone engines
• Works on minibikes like MB165, MB200 and Baja models
• Suitable for engines rated roughly 2–6.5 HP at typical operating RPMs

What materials and durability features should I expect?

The clutch is manufactured from high-grade, impact-resistant steel formulated to resist wear and dissipate heat effectively during repeated use. The hardened construction helps maintain tooth profile and engagement reliability under normal recreational loads.

• High-impact, wear-resistant steel body for long life
• Designed for efficient heat dissipation during operation
• Hardened teeth help resist premature wear with correct chain tension

What comes in the box and what should I check before installation?

The kit ships with the clutch assembly plus a mounting bolt, a washer kit and a small wrench so you have the basic parts to fit it. Before installing, confirm your engine crankshaft is 3/4" with a 3/16" keyway and verify the clutch tooth count and chain size match your drivetrain.

• Includes clutch, bolt, washers and a wrench for installation
• Confirm crankshaft diameter and keyway size before purchase
• Inspect chain size (#40, #41 or #420) and sprocket alignment when fitting

Who this is for: This KRGUOD centrifugal clutch is aimed at hobbyists, go-kart and minibike owners, small-engine repairers and DIY mechanics who need a reliable replacement or upgrade for 3/4" shaft engines like the Predator 212 and many 5.5–6.5 HP clones. It’s best suited to recreational riders, light-duty racers and anyone wanting smoother engagement and improved drivetrain longevity on small engine platforms.
