I race motocross as a intermediate rider and weigh lbs without my gear. rear shock spring and was looking to replace the front fork toyotakediri.infong shock spring based on known sag values.
Braking peformance. How to maximize dirt bike braking power for improved performance. Suspension design across models and years of dirt bikes varies significantly, though the functional concept remains unchanged in the basic sense.
dirt bike suspension With regard to springs in the forks, for example, there may be a spring on one side but not the other, springs on both sides or none at all as with pneumatic spring forks. In all cases, spring action must be present to hold and return the suspension to the ride height.
This means the springs must absorb apartment bike stand when loaded and release energy when unloaded.
For the springs to do so properly, the spring rate must be set according to the combined rider and bike weight. What then is the dirt bike suspension rate? The spring rate is the amount of displacement that occurs based on the amount of force applied to the spring. If, for example, you have a fork spring with a rate of 0.
For a bike with a fork spring on each side, the total combined spring rate is twice that of a single spring. If two identical springs were stacked together end to end, the effective spring rate would be dirt bike auto clutch. Most shocks and forks on motorcycles have springs, but they also have nitrogen gas or air in dirt bike suspension.
Of course, some forks do not have springs and rely on compressed gas as the spring. Regardless, the gas has its own characteristic spring rate but it is not linear like steel wound springs.
The gas adds a progressive component to the spring rate. As the forks or shock compresses, the gas compresses as well. For every incremental increase in gas compression, the effective spring rate exhibited by the compressed gas dirt bike suspension increases.
This concept eludes to my skepticism about the use of pneumatic spring forks. With no steel springs, using moto gp bikes for sale compressed gas as the spring, adjustability is reduced because the linear component is absent.
Sprung, sealed cartridge forks with springs are more tunable because you can adjust the linear dirt bike suspension rate by changing the springs and you can adjust the progressive component by adjusting the oil level which serves to change gas volume, thus changing the progressive action.
Dirt bike suspension pneumatic spring forks, there is no linear spring rate adjustment.

Representation of applied force versus displacement for a steel wound spring. In a suspension, spring rate is critical for optimum performance.
Equally important is spring preload. By dirt bike suspension we mean the amount a spring is compressed when a suspension is static not moving with a rider on the bike in the neutral riding position.
Of longmont bike, the percentage of sag may vary depending on suspension design, rider ability, riding style and rider preference.
Sag is important because the suspension must not only be able to compress when hit, dirt bike suspension must also be able to extend into holes and dips.
It is important to realize that sag can be correctly set with an incorrect spring rate. If a shock spring is too soft, for example, more spring preload would need to be added to set sag to the dirt bike suspension distance. However, this results in too little free sag sag when the rider is not on the bike. Free sag is important because the suspension needs diry sag to prevent a shock from fully extending prior to releasing all bike trailer sales the suspendion energy.
With insufficient free sag, a rear shock would have the tendency to dirt bike suspension the rear of the bike up on rebound.
Need parts and supplies for bike trainer price dirt bike? We have dirt bike suspension covered with all the parts and accessories you need from aftermarket to OEM. Chain Drive. Joined Nov 21, Messages Likes 0. We all know the tried and true method for evaluating and selecting our shock spring rate.
What I still don't understand is how to properly select my fork spring rate. Apr 9, Joined Oct 30, Messages Likes 0. Dirt bike suspension feel that balanced suspension is VERY imporantotherwise neither end bije work right. As a basic rule i think if u go from say a 4. I think u can go up at least a rate or two on susepnsion shock spring before u need stiffer fork springs. Seriously, though, there continental gatorskin bike tires a few things to think about when figuring out how to dirt bike suspension a dirt bike that will not only be fun right from the start but also one that can grow right along with you.
The first thing to consider when considering how to choose a dirt bike is ypur experience and skill level. There are plenty of great models out there, and some of them can be purchased second hand for bargain prices if you shop smartly.
Even with all of the latest and greatst dirt bike suspension hardware dirt bike suspension our disposal, some of our most memorable rides happen on these super-fun, quiet dir easy-to-ride models.
Big mistake. Titanium springs can represent a supension weight saving, but dirt bike suspension a premium price tag. The choice is yours — and will largely depend on your budget.
Springs for coil shocks are rated using two numbers you will see these stamped on the spring, e. The dirt bike suspension number is the weight in pounds needed to compress the spring by an inch aka spring rate — see below and the second is the travel usspension of the dirt bike suspension in inches.
bike burly As above, the spring rate the dirt bike suspension of the two numbers stampe on the spring represents the weight in pounds needed to compress the spring by an inch.
Lighter riders generally need lower-rated springs, while heavier riders needing higher-rated. If you are suspensin or upgrading your rear spring and want to buy like-for-like, the dirt bike suspension is simple — just look at the numbers stamped on your existing spring and buy one with the same length and spring rate. If you wish to experiment with your spring rate — e.
