Dry Clutch Sprocket – 428 Chain – 25mm Bore – Honda GX390 Go Kart

Replacement drive sprockets for Honda GX390 dry clutch go kart applications. Fits directly onto the dry clutch output and drives the 428 chain to the rear axle — the correct specification for high-power outdoor track karts running a centrifugal dry clutch setup rather than a wet clutch or reduction box.

Typically found on Sodi, TBKart, and other high-power outdoor rental and concession karts where the GX390 is run in direct dry clutch configuration. Tooth count works in combination with the rear axle sprocket to set the overall gear ratio — a smaller front sprocket raises top speed, a larger one improves acceleration out of corners.

Specification:

• Chain pitch: 428
• Bore: 25mm
• Application: Dry clutch

Compatible with: Sodi, TBKart, and most GX390 dry clutch outdoor karts
