This is my first post so excuse me if I get anything wrong but when I sit on my bike, my forks suspension does not travel resulting in 0% sag. My suspension is not on lockout and I'm a very light rider so my preloaded is all the way on the - side. Any help. Thanks.

    More info needed.

    What is the fork?

    How much do you weigh?


    Some coil forks have replaceable springs, you can get different springs for different rider weights.

    Some coil forks only have one type of spring for all rider weights, light riders will have no sag, heavy riders will have too much sag.
  • Can you compress the fork by pushing down hard on it? If not then I reckon its time to bin it and spend any money you would have spent on getting it serviced on buying a decent/working SH set. Ideally and air sprung one

    if you can moved it then the spring is too heavy for you, replace with a lighter one. if none available/that's impossible, see my first point.

    Both points above assume no corrosion on legs/seals/stantions etc...

    What pressure do you have in them.

    Hi there, it is a suntour xcm fork coil sprung. I am really light for my age category (too light in fact). When I push down on the forks nothing happens.

    You need a lighter spring. But they are basically rubbish, so I would find a decent set of air forks.
