Harley motorcycles use timing chains, not timing belts. This affects maintenance and engine performance.
Harley-Davidson engines rely on timing chains for precise valve operation. Chains last longer than belts and require less frequent changes. For models like the 1967-1981 Harley Davidson 2 Cycle and Sportster 883 or 1200, timing chains offer durability and strength.
Drive belts, such as the JUWEVAZU Rear Drive Belt, handle power transmission but are different from timing components. Knowing the difference helps riders maintain their bikes properly and avoid costly repairs. Timing chains resist wear better in tough riding conditions. This makes them ideal for Harley’s powerful engines. Understanding these parts improves your bike’s reliability and riding experience.
