Regardless of how nice a mud bike and its suspension is, it gained’t provide you with nice efficiency if don’t know the way it works, perceive the best way to modify it, or maintain it nicely maintained. Getting your suspension proper could be barely difficult, even in case you’ve been using for some time. Issues are straightforward to misidentify, and typically a change that works nicely for one drawback makes one other drawback worse. So, take a look at these fundamentals earlier than your subsequent experience to enhance your suspension and efficiency.

Your springs are there to carry each you and your bike up, so be sure to have the suitable spring charge. It will rely partly in your dimension and partly in your using type and preferences. Proper out of the field your spring charges are often set for somebody of common dimension — this usually means 75 to 80 kilos or 165 to 176 kilos. In case you are lighter or heavier, that spring charge gained’t carry out as nicely for you.

Subsequent, decide your static sag and laden sag. Assuming your bike is 125cc or extra, the static sag ought to be round 25 to 40 mm. Smaller bikes can deal with a static sag between 8 and 10 mm. In case your static sag is simply too low you want a stiffer spring; if it’s too excessive you want a softer spring. Test the static sag like this:

Put your bike on a stand, wheels off the bottom. Measure vertically from the rear axle bolt to any level in your bike for references, just like the rear mudguard or the aspect plate. Now take the identical measurement with the bike off the stand, upright, with the clickers set to gentle. Subtract that second measurement from the primary, and you’ve got the static sag.

Test the laden sag by having somebody take that very same measurement whilst you sit on the bike. Subtract that new measurement from the on-stand measurement and you’ve got the laden sag; for bikes 125cc and bigger this ought to be about 95 to 105 mm, and for smaller bikes search for 65 to 85 mm. Test your proprietor’s handbook, although, as a result of each bike is exclusive. Identical to the static sag, a low laden lag means you want a stiffer spring; a excessive laden sag means you want a softer spring.

If the laden sag is fallacious, modify the spring preload. Use a hammer and punch to launch the shock spring’s prime collar. Then faucet the collar to compress or launch it relying on whether or not you want the spring to be stiffer or softer. After you’re completed, bear in mind to tighten the highest collar so it’s locked into {position}.

In case your bike kicks loads that could be as a result of it has an excessive amount of compression, an excessive amount of rebound, and even not sufficient rebound. Strive extra compression first; if that doesn’t work, transfer on to checking rebound.

High of the entrance forks compression

Begin out by setting your rebound and compression adjusters to straightforward clicks based mostly on the requirements on your bike. In reality, it’s a good suggestion to mark the usual setting in your bike so you’ll be able to default again to it rapidly as wanted. For those who can’t work out what the usual suspension settings on your dust bike are, rely what number of complete clicks it has after which set them at 2/3 out or open.

Backside of the fork (rebound)

Now that you simply’re set at customary, experience to get a way of what wants adjustment. Bear in mind, solely modify one factor at a time, and by no means greater than 3 clicks in a single path without delay. The screw on the prime of the fork adjusts compression; the one on the backside adjusts rebound. Each have “S” and “H” labels which imply gentle and exhausting. Winding the compression screw clockwise towards H makes the fork more durable, and vice versa. Winding the rebound screw in direction of H slows down your rebound pace for rolling terrain with bigger bumps; winding it in direction of the S will increase the rebound pace for rougher, smaller bumps.

Bear in mind to alter your shock and fork oil each 20 hours. (It’s best to exchange elements that put on down reminiscent of seals and bushings each 40 hours.) Oil will get contaminated and breaks down over time, and this causes fading in your suspension. Extra play can even trigger worn bushings which in flip result in friction and leaky seals.

Most dust bikes right this moment name for 5wt fork oil as a result of they want to deal with greater temperatures and mount extra resistance to breaking down and fading, shocks usually use lighter 2.5wt oil. Altering the peak of your fork oil alters damping and adjustments the quantity of air area within the fork. Including extra oil stiffens the fork whereas taking oil away softens it; add or take away oil in very small quantities — not more than 10ccs at a time — till you’ve the impact you’re after.

Getting your suspension precisely the place you need it to be is a trial and error course of. It’s labor- and time-intensive, however in case you don’t like the way it’s going at first, simply carry on making an attempt as a result of it’s the one factor you are able to do to get your bike really dialed on your top, weight, and using type. You possibly can at all times restore your inventory settings and provides it one other go. Your effort and a focus might be rewarded in the long term with higher suspension settings, more practical mastery of obstacles, and improved using methods.
