Ensure maximum power transfer with this Universal Parts 219H Heavy-Duty Metric Roller Chain. The “H” designation signifies thicker side plates and heavy-duty pins engineered to withstand higher tensile loads than standard 219 chains — making it the go-to choice for high-performance karting, pocket bikes, and custom scooter drivetrains. This 5-foot section can be cut to length or combined using standard chain tools.
Key Features
Heavy-Duty (H) Rating: Reinforced side plates provide superior resistance to fatigue and stretching under high-RPM racing loads
Precision Metric Pitch: Designed for 219 sprockets used in high-RPM racing and performance engines
Heat-Treated Alloy Steel: Minimal stretch and long service life under extreme conditions
Customizable Length: 5-foot section — cut to size or join sections with a chain rivet tool
No Master Link: Designed to be riveted for maximum safety and reliability in racing applications

Compatibility
Application
Compatible Models & Engines
Racing Go-Karts
Rotax Max, IAME Leopard, X30, PRD Fireball, Comet, and most 2-stroke TAG/kart engines using 219 sprockets
Performance Scooters
Custom 2-stroke motorized builds, Goped (with 219 conversion kits), and specialized racing minimotos
Pocket Bikes
European racing pocket bikes (Polini, BZM, GRC) using metric 219 drive systems
Industrial / Custom
