How can you improve CSC TT250 suspension for off road?

[Essayons]

Good day all. What can be done to improve off road performance for the TT250?
I realize you can change sprockets, chain and tires. What about the rear shock/spring and the front springs and valve? The main thing I am wondering is what set up and what brand would work? Has anyone done this?

thanks.

Ok... Try setting your sags and tell us "me'. how close you get with the
factory springing...
how much do you weigh?
do you ride standing or sitting?

The suspension is at the stock setting from CSC. I ride sitting most of the time(because I'm lazy) but stand when I think I need to. I weigh 190lbs.

[pete]

what adjustments is there ?
At 190lbs and sitting all of your
weight is being carryed by the suspension..
is it bottoming over bumbs..

[Essayons]

You're probably right Pete. I'm going to try riding standing more often and take note of the performance.

If you need an "upgrade"... Sonic Springs (most of the time) can make up some custom stuff for your motorcycle needs

If you haven't already, change the fork fluid to something a little stouter. I use Bel Ray 10W. I also added about 5cc's extra in each fork. It helped.

On the damepning on the forks, screw the dampening rods down to 'stop", then back out a turn. Adjust from there.

The rear shock will just take playing with. The worst part is the massive air box is in the way. Tighten up your spring rate one full turn at a time and increase your dampening one click at a time.

It took a while but I got our TT dialed in about as good as a Chinabike will get.

If you are standing on the pegs, or sitting on the seat, there is still 190 pounds being supported by the suspension. Standing on the pegs just lowers your center of gravity giving you more stability.

O dear....

You would be totaly correct if you ride stiff legged while standing.. direct body weight transfur to the bike..
but I don't think meany people do...I don't...


while standing the riders legs are taking a good percentage of your body weight
slowing it's transfur to the bike/suspension.. Where if you are seated the the body weight is
transfured instantly to the bike/suspesion..
Standing and useing your legs as shocks you are making yourself lighter in the first
stage of weight transfur to the bike...

How the can lifteing your body weight higher by standing lower the COG of the bike..
Stability comes from the rider being able to react faster to what the bike is doing and useing his body as a counter balance and giveing the bike more freedom to move around while standing..

This is a physics question. 190lbs on the bike is going to always be 190lbs on the bike unless you jump off it at some point.

Let's use a different example; firearm recoil. With firearm weight, bullet weight, powder weight, and velocity being equal, the amount of recoil a gun has does not change because of adding a recoil pad to the firearm. It only changes the amount of "perceived" recoil by changing when the pressure is applied in the time line.

The bike plus rider does not get lighter just because you are using your legs and arms as the recoil absorber. People don't float while riding. Your body is only affected differently since upward energy is not transferred directly into your body; rather, it is dissipated by your knees and elbows.

Another thought on this....How much does an airplane weigh in level flight?

ok..maybe useing "lighter" was a bad choice of words...
But that dosn't change the fact that setting suspension for
a seated rider and a standing rider is totaly diffrent..

Read what Pete said again. You missed his point. He is right...ARH

Honda 10w fork fluid definitely stiffened up the front end for me i found the rear end to be stiff enough for my weight. https://www.amazon.com/gp/product/B0...AUOHM36P&psc=1

It was already covered, but I just feel like being a broken record.

The first thing you should do with any bike is set the rider sag by adjusting spring preload. This will ensure that your suspension, with your total rider weight on it, will have the correct compression and rebound travel. This will ensure that the front and rear of the bike are loaded correctly and evenly as too much or too little rear sag will greatly affect the function of the forks, and could make for some terrible handling.

A simple rule of thumb for most bikes is the 1 in 3 rule. Given the TT250's 6.5" rear travel and 6.2" front travel, I would aim for around 2 1/4 to 2 1/2 inches of sag front and rear. For the forks a couple of zip ties around the tube are a good simple way to measure the movement. The rear will require finding a good fixed point to measure from. In either case it helps to have a helper.

There is also free sag to consider once you have your rider sag dialed in. This is a good way to determine if your spring rates need to be changed, but finding the right balance of rate/preload/free sag can be a bit frustrating. If you measure about 15 to 25mm of free sag, then consider it good.

From there, follow the suggestions for damping adjustments. I personally always start with my forks and shock(s) in the middle most setting and adjust up or down from there. Having a few members here with recommended settings can help simplify that process a little, such as the suggestions above.

it's no big drama... he got hung up on one poorly choisen word then focused
his entire reply on and around it...

sort of... can't see the forest because the trees are in the way..
