Show original supplier description
The YSS MZ456-365TRL-14-X rear monoshock absorber is engineered to elevate your motorcycle's performance and riding dynamics. It offers a versatile variable length ranging from 360-370 mm, providing adaptability for various setups. The emulsion mono gas damper system is designed for consistent damping performance, while the striking red spring, measuring 56 mm in diameter and 185 mm in length, contributes to both aesthetics and responsive road feel. This shock absorber is equipped with a variable preload adjustment, allowing riders to fine-tune the suspension to match different loads and riding styles, ensuring a personalized and optimized experience. Key specifications include a robust 45 mm piston diameter and a 16 mm hardened shaft with low friction for enhanced durability and longevity. Installation is facilitated by a 25 mm upper fork mount width and a 12 mm lower eyelet mount inner diameter. The YSS MZ456 series represents the Topline range, featuring self-adjusting mono gas dampers with a 50mm radial billet milled piston. It offers a 60-click rebound adjustment, controlled by a knob at the bottom, and is designed to be length-adjustable where technically feasible. This shock absorber is model-specific, ensuring optimal integration and performance with your motorcycle.
