Hello everyone I have just purchased a 2010 280 pro from ebay unfortunately the bike arrived with the usual hidden problems not mentioned by the seller,after pulling my hair out rebuilding the master cylinders and rear caliper, then 2 days trying to bleed it (hardest brakes to bleed I have ever encountered) got that sorted now moving on to the suspension I have fitted a stiffer rear spring and purchased a jitsie stiffer fork spring.what I find strange is it states to replace just the one spring but does not say which fork leg and I also can't find what the standard preload setting should be on the shock spring can anyone help thankyou

I think all modern bikes use a single fork spring in one side and the other leg controls damping.

Yes, forks are almost always NOT the same.

Sorry this is all new to me only worked on enduro and mx bike suspension,this is my first trials bike thanks for the info

Its the same for many MX bikes

I think we have our wires well and truly crossed here are you saying mx and enduro bikes run just one fork spring I've just rebuilt my ktm300exc wp open chamber forks and had to replace both springs never heard of just doing the one

Your bike does take two springs. But why are you changing the suspension before you get some time on the bike? This is trials, softer is better.

On almost al newer suspension rebound and compression legs are used. So the forks are not identical, but have different function. And now the hype is air forks.
