## Regina Dual Black 520ZRA Drive Chain - Strength and Reliability for Your Motorcycle The Regina Dual Black 520ZRA drive chain is an excellent choice for motorcycles up to 600cc. Made of high-quality alloy steel, with solid bushings and rollers, shot-peened plates, pins, and rollers, it guarantees high fatigue resistance and long-lasting performance. ### Advanced Technology for Exceptional Performance The Regina 520ZRA chain has been pre-stretched, which minimizes its elongation during use. Z-Ring seals provide excellent lubrication and protection against contamination, resulting in a longer chain life and less frequent lubrication intervals. Additionally, laser markings on the outer plates facilitate the identification of size, model, and origin. ### Easy Installation and Availability The Regina Dual Black 520ZRA chain is available in two versions: with a clip for manual closing (requiring no special tools) and with a rivet for closing using a chain breaker. The black, natural steel color gives it a discreet yet stylish look. ### Key Features: * **Size:** 520 (roller distance: 15.88mm, width: 6.35mm, roller diameter: 10.16mm) * **Tensile Strength:** 33800N * **Seals:** Z-Ring * **Color:** Black (natural steel color) * **Brand:** Regina Chain - synonymous with quality and reliability in the motorcycle industry.
