How do you adjust the preload on a rear strut?
Rear shock preload To adjust the preload on your bike’s rear shock, you will need a C-spanner to loosen the top locking ring and spin it up the shock to gain access to the adjuster ring. If you want to increase preload so the spring has less travel and to make the bike feel stiffer, turn the adjuster ring clockwise.
What does suspension preload do?
Preload is used to adjust the shock or spring to the correct range of operation within the suspension’s travel-more preload will raise the bike up on its suspension, keeping you near the top of its travel. With less preload, the bike sits lower and closer to the bottom of its suspension travel.
What is preload and damping?
1y. Compression damping is the rate which the suspension compresses, rebound compression is the rate at which is springs back to it’s original position. Preload basically means you pre compress the suspension to stiffen it or basically reduce the maximum suspension travel allowed.
How do I set rear preload?
1 Setting the spring preload or “sag” Check swing arm and wheel bearings/bushes to ensure there is no wear. Lift the rear of the bike until the suspension is completely extended. Take a measurement from the axle to a point directly above on the rear sub frame. Let the bike down on its suspension and measure again.
Does preload affect alignment?
3. More preload, more lift height will affect alignment. Usually recommended to get an alignment after adjusting lift height significantly.
Can you adjust rear preload and still have static sag?
As mentioned before adjusting rear preload does not change the stiffness or softness of your springs. So you may very well find that even if you get the Rider Sag in the sweet spot of 35mm, your Static Sag may still be outside the ideal range. Try your best to ensure you have a bit of static sag, otherwise your suspension can top out.
What should my Rider SAG be for rear suspension?
If your Rider Sag is above 40mm then it means your rear preload is too soft and conversely, below 30mm means it’s too hard. Static Sag is how much the bike’s own weight acts on the rear suspension. The ideal range here is between 5mm and 10mm.
What should my rear preload be for street riding?
Some prefer to be as close to 30mm as possible, but for general street riding and the occasional track day, around 35mm should be fine. If your Rider Sag is above 40mm then it means your rear preload is too soft and conversely, below 30mm means it’s too hard. Static Sag is how much the bike’s own weight acts on the rear suspension.
How does rear preload affect the spring rate?
Just to clear up any confusion – adjusting rear preload in no way either stiffens or softens your rear suspension. It also does not change your spring rate. All it does is change up or down the initial position of the suspension, either when you’re sitting on it your bike or not – these terms are known as Rider Sag and Static Sag.

How to measure and adjust rear preload adjust motorcycle?
Place the bike back down like you’re parking it but try to have it as upright as possible (i.e. not leaning on its side using the kickstand). The final measurement we take will provide us with the fully loaded length of the rear suspension. This is the length of the rear suspension when you sit on the bike.
