Helping customers correctly select motorcycle shock absorbers.

# Why Do Customers Buy the Wrong Motorcycle Shock Absorber?

Choosing the right motorcycle shock absorber is more complicated than simply selecting the correct motorcycle model. Many customers purchase the wrong shock absorber because they focus on the vehicle name or price while overlooking important installation and suspension specifications.

Here are the most common reasons customers buy the wrong motorcycle shock absorber — and how to avoid them.

## 1. Choosing Only by Motorcycle Model

One of the most common mistakes is searching for a shock absorber using only the motorcycle model.

For example, the same motorcycle model may have different versions, production years, suspension systems, or mounting designs.

A shock absorber listed for the same motorcycle model may not necessarily fit every version.

What to check:

* Motorcycle brand

* Model

* Year

* Engine size

* Front or rear suspension

* Original shock absorber dimensions

* Mounting design

Always confirm the actual suspension specifications before placing an order.

## 2. The Shock Absorber Length Is Wrong

Shock absorber length is one of the most important measurements.

Customers sometimes measure the overall length incorrectly or confuse the shock absorber body length with the eye-to-eye length.

For most motorcycle rear shocks, the correct measurement is usually taken from the center of the upper mounting hole to the center of the lower mounting hole.

A difference of only a few millimeters can affect motorcycle geometry, ride height, handling, and suspension performance.

## 3. The Mounting Hole Size Is Different

Even when the shock absorber length is correct, the shock may still not fit because the mounting holes are different.

Important measurements include:

* Upper mounting hole diameter

* Lower mounting hole diameter

* Upper mounting width

* Lower mounting width

* Mounting type

* Sleeve or bushing dimensions

For example, a 12 mm mounting hole and a 14 mm mounting hole cannot be considered directly interchangeable without the correct hardware.

## 4. Customers Choose the Wrong Suspension Travel

Suspension travel is another common source of mistakes.

A longer-travel shock absorber is not automatically better.

If the travel is too long, the suspension may cause:

* Excessive ride height

* Incorrect suspension geometry

* Tire or fender interference

* Chain or swingarm clearance problems

If the travel is too short, the suspension may bottom out more easily and provide insufficient control.

The shock absorber should be selected according to the motorcycle's original suspension design and intended riding conditions.

## 5. Spring Rate Is Not Suitable for the Rider

Two motorcycles can use shock absorbers with the same dimensions but require different spring rates.

Spring selection depends on factors such as:

* Rider weight

* Passenger weight

* Luggage

* Motorcycle weight

* Riding style

* Road conditions

* Track or street use

A spring that is too soft may cause excessive sag and bottoming.

A spring that is too stiff may make the motorcycle uncomfortable and reduce tire grip on uneven roads.

Therefore, correct dimensions do not always mean correct suspension setup.

## 6. Confusing Front Forks with Rear Shocks

Some customers search for motorcycle suspension parts without clearly identifying whether they need a front fork or rear shock absorber.

The two systems have completely different structures and installation methods.

Before ordering, confirm whether you need:

Front Suspension → Fork / Front Fork

or

Rear Suspension → Rear Shock Absorber / Rear Suspension

## 7. Different Motorcycle Generations

Manufacturers sometimes change suspension specifications during a model update.

Two motorcycles may have the same model name but different:

* Production years

* Frames

* Swingarms

* Mounting points

* Suspension lengths

* Spring rates

This is why the year of the motorcycle can be just as important as the model name.

## 8. Customers Buy Based Only on Price

The cheapest shock absorber is not necessarily the best choice.

A motorcycle shock absorber is responsible for maintaining tire contact with the road and controlling the movement of the motorcycle.

Important factors include:

* Material quality

* Spring quality

* Seal quality

* Damping performance

* Adjustment range

* Manufacturing accuracy

* Load capacity

* Compatibility

A lower price can sometimes mean fewer adjustment options or lower-quality internal components.

## 9. Customers Do Not Provide Enough Information

Sometimes the problem is not the product — it is incomplete information when placing the order.

Before purchasing, customers should ideally provide:

Motorcycle Brand + Model + Year + Engine Size + Original Shock Dimensions + Photos

A clear photo of the original shock absorber can also help confirm the mounting design.

10. The Best Way to Avoid Buying the Wrong Shock

Before ordering a motorcycle shock absorber, we recommend checking the following:

Motorcycle brand

Motorcycle model

Model year

Engine displacement

Front or rear suspension

Eye-to-eye length

Suspension travel

Upper mounting hole diameter

Lower mounting hole diameter

Upper mounting width

Lower mounting width

Spring diameter

Spring length

Rider/load requirements

Original shock absorber photos

Conclusion

Buying the correct motorcycle shock absorber is not simply about matching the motorcycle model.

Correct fitment requires the right dimensions, mounting specifications, suspension travel, spring rate, and intended riding conditions.

At RFY, we recommend confirming the motorcycle model and suspension dimensions before ordering. If you are unsure which shock absorber you need, providing photos and measurements of your original shock absorber can greatly reduce the risk of purchasing the wrong product.

Measure correctly. Choose correctly. Ride with confidence!
