YSS Topline Z-Series MZ456 Rear Shock Absorber

YSS motorcycle mono shocks with gas pressure shock absorber. Gas pressure shock absorbers are oil pressure shock absorbers that contain high pressure nitrogen gas inside the cylinder to minimize foam or bubbles in the shock oil. This causes the damper to operate smoothly. YSS gas pressure shock absorbers can be divided into two groups. Emulsion Gas Pressure Shock Absorber Emulsion gas shock absorbers are a mixture of oil and gas shock absorbers where nitrogen gas is compressed to mix with the oil and increase the pressure to make the shock more flexible and responsive to the driver. Gas-pressure shock absorbers with external gas reservoir. YSS gas pressure shock absorbers with external gas reservoir have the shock oil and gas separated, which prevents bubbles in the oil and allows better cooling.
