How To Articles

As someone who enjoys riding motorcycles, I have always been intrigued by the complexities of suspension adjustment. Getting your suspension set up correctly can have a significant impact on your comfort, handling, and overall performance. One tool that I have found to be essential in my suspension tuning process is the Motool Slacker.

The Motool Slacker is a user-friendly device designed to help you measure and adjust the sag on your motorcycle’s suspension. In simple terms, sag refers to the amount your suspension compresses under the weight of the bike and rider. It plays a crucial role in how your motorcycle handles, as it affects everything from cornering to braking and even straight line stability.

Using the Motool Slacker is incredibly straightforward. First, you attach the device to your motorcycle’s rear suspension using the included hook and strap. Then, you turn on the unit and zero it out by pressing the “Zero” button. Next, you lift the rear wheel off the ground and apply pressure to simulate the bike’s sag. The Motool Slacker will display the sag measurement on its digital screen in real-time.

What I love about the Motool Slacker is its accuracy and ease of use. The device’s digital screen is easy to read, even in direct sunlight. It eliminates any guesswork involved in measuring sag, allowing you to achieve precise and consistent results every time. This is especially beneficial if you’re making adjustments at the track or during a suspension setup session.

Once you have your sag measurement, you can make adjustments to your suspension preload to achieve the desired sag value. Adjustments are typically made by turning the preload adjuster on your rear shock or by adding or removing preload spacers.

It’s important to note that the ideal sag setting varies depending on various factors, such as your riding style, weight, and type of motorcycle. A good starting point is to aim for around 25-30% sag for the rear suspension and 30-35% sag for the front suspension. However, it’s always best to consult your motorcycle’s owner’s manual or seek advice from a professional suspension tuner for specific recommendations.

Overall, the Motool Slacker has become an indispensable tool in my suspension tuning arsenal. It has helped me fine-tune my bike’s setup to suit my riding style and preferences, resulting in improved handling and a more enjoyable riding experience. Whether you’re a weekend warrior or a seasoned track rider, I highly recommend adding the Motool Slacker to your toolbox.


The Motool Slacker is a game-changer when it comes to dialing in your motorcycle’s suspension. Its accuracy, ease of use, and real-time sag measurements make it an invaluable tool for any rider looking to optimize their bike’s setup. Take the time to understand the importance of sag and use the Motool Slacker to achieve the perfect sag setting for your riding style. Your bike will thank you, and you’ll never look back.
