I contacted Race Tech and they have springs for the MC 28, but not a MC 21. Race Tech did not realize the the MC 28 springs will not fit an MC 21. I am in the process of taking apart my forks, measuring the length and OD of the springs. They Race Tech will tray and match the springs with the charts of springs they carry.

Once I have gone through this process I will post the results so everyone has a reference to work from.
