Bike Shock Absorbers

Inside The Motorcycle Shock And How It Works Single-shock rear suspensions are near-universal today. Traditional twin-shock setups are still seen, but exist mainly for reasons of retro style. When the era of longer rear-suspension travel arrived in 1974, it made the best sense to implement it with a single-suspension unit. Why have suspension at all? For decades, American motorcycles had rigid frames?no rear suspension. But as highways improved and speeds rose, rear suspension became necessary to provide chassis stability. Letting just the sprung wheel ride up and down over bumps saved the rider and chassis from their disturbance. The rear shock provides two basic functions: Supporting the weight of the rear of the bike with a bump-softening spring, and controlling any up-and-down oscillations of the suspension by providing damping. Damping is a controlled friction force that drains energy out of unwanted suspension motions, such as the bouncing that would otherwise continue after
