The YSS MZ456 Topline Z-Series rear shock absorber is designed for riders seeking adjustable damping and a sharp chassis behaviour on roadsters. Its preload adjustment is easily done via a nut, allowing for quick adaptation of the ride height and rear end firmness according to load and riding style.

• Piston diameter: 45 mm — ensures consistent response to demands.
• Rod diameter: 16 mm — a compromise between strength and guiding precision.
• Length: 325–335 mm (adjustable ±5 mm) to fine-tune geometry.
• Damping adjustment (compression) to control rebound and absorption based on the terrain.

Assembled in the Topline Z-Series range, this shock absorber offers a wide range of adjustments to enhance road holding, cornering stability, and comfort on varied roads. Easy to implement, it is aimed at riders who want to refine the rear behaviour of their machine without altering the original chassis.
