Motorcycle Shocks

Everyone wants a smooth ride. To get that, you need to have great working motorcycle shocks equipped on your bike. The rear shocks on a motorcycle absorb much of the punishment so your back does not have to. Not all shocks are created equally, though. They range from the very standard coil over shocks to gas shocks with external reservoirs and even air ride shocks. Each style has its advantages and disadvantages, so choosing the right shocks largely depends on your riding style, type of motorcycle and budget.

Most motorcycle come stock with coil over shocks with only oil used for damping. These shocks were just fine for most bikes and casual riding styles and they tend to be the least expensive option. One downside to the standard shocks is that the oil can begin to foam if it is constantly moving and their damping abilities begin to fade. Gas shocks have a pocket of nitrogen to help keep pressure on the oil as well as to keep it cool to prevent the foaming. Many gas shocks also come equipped with a damping adjuster to help you dial in for a smoother ride. Air ride shocks provide the ultimate ride by being the most adjustable.

FAQs on Motorcycle Shocks

What type of shock gives the smoothest ride?

Gas-charged shocks with adjustable damping generally provide the smoothest ride. High-quality suspension systems like Öhlins or Legend are known for comfort. Proper tuning for your weight and bike type is essential. Regular maintenance also ensures consistent smoothness. All that being said, air ride suspensions can provide a very smooth ride as well with the ability to quickly adjust on the fly.

What do shocks do on a motorcycle?

Shocks absorb bumps and vibrations from the road, improving comfort and control. They keep tires in contact with the ground for better traction. Shocks also control the suspension’s movement during acceleration, braking, and cornering. They play a key role in handling stability. Essentially, they balance comfort and performance.

How often should I replace motorcycle shocks?

Shocks generally last between 20,000 and 50,000 miles depending on riding style and conditions. Regular inspection for leaks or sagging helps determine replacement needs. Aggressive riding or rough terrain may shorten lifespan. Signs of wear should prompt earlier replacement. Always follow manufacturer recommendations for your bike model.

How to tell if your motorcycle shocks are bad?

Bad shocks often show leaks or visible oil around the shock body. Excessive bouncing or a rough ride can be signs of worn shocks. Uneven tire wear and reduced handling stability also indicate issues. Listen for unusual noises when riding. If in doubt, have a professional inspect them.

Is it better to ride with your shocks on hard or soft?

The choice depends on your riding style and conditions. Soft settings improve comfort on rough roads but reduce handling precision. Hard settings enhance control and cornering stability but can feel harsh over bumps. Adjustable shocks allow you to fine-tune between comfort and performance. Many riders prefer a medium setting for everyday riding.
