How to Adjust Yfz450R Shocks

Last Updated on September 18, 2022 by Climent Rick

The Yamaha Yfz450R comes with shocks that are pre-set from the factory. However, you may need to adjust them to suit your riding style or terrain. In this blog post, we’ll show you how to do just that!

  • Park your Yfz450R on level ground and turn off the engine
  • Locate the preload adjusters on the shocks
  • There are three adjusting nuts on each shock, located at the top, bottom and middle of the shock body
  • Place a wrench or socket on the top adjusting nut and loosen it until it is completely loose
  • Do not remove this nut completely; just make sure that it is loose enough to turn by hand
  • Repeat this step for all three shocks
  • Use your hands to compress each shock fully and then release it slowly
  • Doing this will help you get a feel for how much preload has been removed from the shocks with the previous step
  • Turn each of the preload adjusting nuts clockwise until they are finger-tight, then use a wrench or socket to tighten each nut one-quarter to one-half of a turn more than finger-tight
  • This will ensure that each nut is tight enough so that it will not come loose while riding, but not so tight that it cannot be adjusted again if needed

Yamaha Yfz 450

The Yamaha Yfz 450 is a four-stroke all-terrain vehicle produced by Yamaha Motor Company. It was introduced in 2003 as a race-ready ATV with a powerful engine and suspension system designed for high performance. The Yfz450 quickly became the top choice for many professional racers and weekend warriors alike, thanks to its exceptional handling and power delivery.

Today, the Yfz450 remains one of the most popular ATVs on the market, and is widely considered to be one of the best performing machines in its class.

How Do You Adjust Yfz Shocks?

There are a few things that you need to take into consideration when adjusting the shocks on your Yfz. The first is what type of terrain you will be riding on. If you will be doing a lot of off-roading, then you will want to adjust the shocks accordingly.

Another thing to consider is the weight of the rider. Heavier riders will need stiffer shocks in order to avoid bottoming out. The next thing you need to do is determine what spring rate you need.

This can be done by using a spring rate calculator or by consulting with a suspension specialist. Once you have determined the correct spring rate, you can then begin adjusting the preload on your shocks. Preload is simply how much tension is on the springs and can be adjusted by turning the adjustment collars located at the top of each shock.

Turning the collars clockwise will increase preload, while turning them counterclockwise will decrease it. It is important to find a balance between too much and too little preload, as both can adversely affect ride quality and handling. Once you have dialed in the perfect amount of preload, it’s time to move on to rebound damping.

Rebound damping controls how quickly the shock absorber returns to its original position after being compressed. This can be adjusted by turning the knob located at the bottom of each shock clockwise for more rebound damping or counterclockwise for less rebound damping. Again, finding the perfect balance is key for optimum performance.

How Do You Adjust Quad Shocks?

When it comes to shocks, there are a few things you need to know in order to properly adjust them. First, you need to determine what kind of terrain you’ll be riding on most often. This will help you decide how much preload, or spring tension, you’ll need.

If you’re mostly going to be on smooth trails, you won’t need as much preload as someone who is going to be doing a lot of off-roading. Next, you’ll want to check the rebound damping. This controls how quickly the shock returns after being compressed.

If it’s set too low, the shock will bounce back too quickly and make for a very jarring ride. Too high, and the shock will take too long to return, which can also lead to a less than ideal ride. The best way to find the sweet spot is by trial and error; start with the rebound damping set in the middle and adjust from there based on how your bike feels while riding.

Finally, if your bike has air shocks (as opposed to coil shocks), you’ll want to adjust the air pressure according to your weight and desired ride quality. Again, this is something that takes some trial and error; start with an air pressure that’s recommended for your weight and go from there until you find what works best for you.

How Do You Set the Preload on a Shock Atv?

There are many ways to set the preload on a shock ATV. The most common way is to use the spring adjusters. These are located at the top of the shocks and can be turned clockwise or counterclockwise to increase or decrease the preload.

Another way to set the preload is by adding or removing shims from under the spring. This will also affect how much travel is available for the suspension.

How Can I Make My Yfz Faster?

If you’re looking to make your Yamaha Yfz450 faster, there are a few things you can do. First, you’ll want to make sure the engine is properly tuned. This includes making sure the spark plugs are in good condition and that the carburetor is set correctly.

You may also want to consider installing a larger exhaust pipe and air filter. Next, you’ll want to focus on the suspension. Making sure the shocks are in good condition and adjusting the preload can make a big difference in how fast your Yfz450 will be.

If you have an aftermarket shock, you may also want to consider having it professionally serviced. Finally, don’t forget about tires! Making sure they’re inflated properly and have enough tread can help you get better traction and therefore more speed out of your bike.

By following these tips, you should be able to eke out a bit more speed from your Yamaha Yfz450. Just remember to ride safely and within your limits – pushing too hard could result in an accident!


In order to get the most out of your Yfz450R shocks, it is important to adjust them properly. There are a few things that you will need to take into consideration when you are adjusting your shocks, including the terrain that you will be riding on and the weight of your ATV. Once you have these factors figured out, you can begin to adjust your shocks accordingly.
