preload

[ivant]

wat's the meaning of Preload ,Rebound and Compression in simple terms?

 

 

ideal for track what's the recommended settings for a 60 - 65 kg?

 

Preload - Also called spring preload. Its how much the spring is pre-compressed. Its used for setting sag.

 

Rebound damping - resistance of the fork/shock from extending

 

Compression damping - resistance of the fork/shock from compressing

 

You can try 40mm front and 30mm rear for rider sag. There are no recommended settings for damping. Its a matter of preference. The ultimate measure will be the stopwatch though.

Why not you read the entire thread before asking questions.

where to get 'C' spanner? All use same tool?

[Acer1337]

Yeah, where to get a C spanner? The shop where I changed my suspension to a YSS one didn't give me anything.

How about bike with only rear adjustable shock? Does it make sense to adjust the rear only?

[SpiritualRain13]

Definetely Bro. If U 're heavy then better reset. Like wen U sit on the Bike & the Spring Compress alot, confirm wen cornering Bike will b damn wobbly, so U will nid 2 Tighten the Spring/s. But alwayz remember 2 jack up the Rear 1st making the Suspension "free" then only U cn go to tighten the Spring/s w/o damaging the Thread. Its Best wen the Compression is juz slightly wen U sit on the Bike from Stationary. Prefrence differ fr ppl.

 

C Spanner cn b bought fr any Tools Shop, nearby LAB gt a few. But If no haf then can also knock the End Screws Slowly & Carefully using a long Rod / Shaft Loosen the one further fr away Springs 1st then tightened the ones closest 2 the Spring/s making the Spring/s Tighter, after Done then only tightened the one U loosen earlier. Woola Done.....

Hi guys. I want to ask ah, lets say after the forks are serviced and they are very hard after that. Is this normal?

these feelings are very subjective, and different types of bikes, track bike, to dirtbike have specific suspension requirements. Some forks are gas filled. So if you tell us what bike is that, the right answer will be more forthcoming.

 

if before servicing your forks felt like pogo stick ie, no dampening, then after servicing, filled with the proper oil, then the fork will definitely feel firm as it has regained it's dampening property.

 

Check with the mechanic, if they have done anything to the preload as that would have a direct impact on the firmness. The worst thing can ever happen is that the fork was not assembled properly.

I ride a YBR125. My mech says the forks stiffness cannot be adjusted. He said its because the oil is new.

 

Before, like what you said, it was like a pogo stick. Very bouncy, very soft. I cannot feel bumps on the road. But now, after the forks have been serviced, the forks are super hard and stiff. Last time i can push my forks down almost all the way with just my body weight, now it only goes like 1/4 to halfway.

 

Is this normal?

The weight of the oil will also determine firmness. But you use the word stiff and I use firm, so I am not even sure if we are talking about the same thing

To able able to push the fork right down with just your body weight is definitely not right unless you weigh like Sheik Haikel. I am sure your fork had bottom out when riding fast over speed humps.

 

However, it should not feel super hard for a bike like the YB125.

 

 

Is this normal?

 

I wouldn't know whether that is normal or not, it is best you test it with another YB125.

I weigh 98kg. The front forks can go almost all the way down before i had it serviced. Now the forks are hard. Like when i go over speed bumps, i feel the bump. Hard. Or any other bump. When i jam my front brakes, the rear wheel will rise up. In the past, i could never do that.

 

Normal bro?

Even on the most plush dirt bike fork suspension, you can still endo if you ride fast enough.

 

There is no way we can comment on the state of your fork over the forum. Check with your friends if they are knowledgeable about bikes, otherwise, bring your bike to another bike shop for a second opinion.

Alright thanks Demon!

For riders who might want the "bling" look and adjust preload on the fly.

When i serviced my forks in December last year, they were hard. Now in September, they are very soft. Its like when i sit on my bike, the thing goes more than 75% down. I think YBR front forks are very soft by default. Besides putting in heavier oil and losing weight, is there any other way to stiffen the front forks like you can the rear suspension which are those spring type?

[fastgixx05]

Thanks for the helpful tips! Will try this one out for sure..

[HantuRaye]

Hi all...im riding spec3 juz wanna know how adjust ohlins suspension to soft....
