YSS Scooter Twin, rear shocks

YSS twin shocks for scooters with oil or gas shock absorbers. YSS oil shock absorbers can be divided into two groups. Single tube shock absorbers Commonly used shock absorber These shocks are light, inexpensive, and have good heat dissipation Upside down installation only Double tube shock absorbers Durable and smooth because two valves work together If the outer tube is hit by anything, the shock will still work, because the piston in the inner tube will not be damaged 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
