EK Chain 520SR-114 Heavy Duty 520 SR Motorcycle Chain 100ft Roll

The EK Chain 520SR is a heavy-duty version of EK's popular sport chain, designed for reliable performance in lower horsepower dirt bike, ATV, and street motorcycle applications. This 100-foot bulk roll provides excellent value for shops and racers who need multiple chains or custom lengths.

Key Features:

• Solid bushings and solid rollers engineered for extended service life and durability
• Heavy-duty construction with large 5.08mm pins and 2mm thick side plates
• Impressive 7,260 lb. tensile strength despite compact 520 pitch size
• Quad-staked riveting ensures secure master link connection and reduces risk of failure
• 520 pitch offers lighter weight than 530 chains while maintaining strength for most applications
• 100-foot bulk roll format allows custom chain lengths and cost savings

The EK 520SR chain strikes an ideal balance between strength and weight, making it perfect for off-road motorcycles, sport ATVs, and street bikes with moderate power output. The solid bushing and roller design resists wear better than standard chains, while the oversized pins and plates provide a safety margin well beyond typical 520 chain specifications.
