What are the benefits of having a mono-shock and twin shocks on a motorcycle?
Shocks, a crucial part of a motorcycle's suspension system, absorb bumps and reduce the chances of losing control. Shock can be made from many different materials including chrome-silicon steel, but the most common type is a gas-charged oil tank with a coil spring inside. The function of a bike shock absorber is to dampen or absorb vibrations from the bike's wheels. When riding over rough terrains, such as pavement cracks or potholes, or hitting road hazards the suspension system will oscillate (move back and forth).
There are many different types of suspension systems on motorcycles including front suspension, rear suspension and swingarm suspensions. The main purpose of these components is to keep the rider in control as he or she rides over rough terrains such as bumps, potholes and road hazards. Front suspension consists of the fork, headstock (upper), steering stem (lower) and handlebars.
There are mainly two different shocks popular in the commercial market, mono-shock and twin shocks. Commuter bikes are more likely to have twin-suspension shock absorbers than mono-suspension shock absorbers found on high-performance bikes. Twin suspension motorcycles use two shock absorbers to absorb bumps more effectively and reduce bouncy rides. A mono-shock has one shock absorber attached to the frame and a twin-shock has two parallel shocks connected to the rear wheel whereas a dual suspension has two shocks connected on both sides of the frame.
No matter how carefully you tune a dual shock setup, one shock will compress differently than the other. Mono-shock eliminates any likelihood of an imbalance between the two. Many mono-shocks have variable linkages that allow the impactful spring rate and cushioning to be reduced as the suspension is moved away from "neutral’. When compared to a mono-shock, the ride with a twin shock will feel "bouncy." Because the suspension absorbs some torque, the throttle response will be less responsive. As a result, the ride is bouncier and more comfortable.
At the end it’s a matter of preference. What is more important to you? A constant tire contact with the asphalt or a smooth ride which is bouncier? This is a classic age-old trade-off between performance and comfort.
