Would they be a stiffer replacement for the 2009 KLX? Will they fit?

factory connection fork springs pn lsb-048 .48kg rating(sells for 100 take 50)
factory connection rear spring aln-0056/5.6kg spring rating(sells for100,take 50)

 

id love to know myself, but i think the klx250s springs are 43mm in front and are a .38kg rating with the back a 5.6 from factory

 

The fronts springs won't work. Ours are 43mm and KX250 is 48mm diameter. The rear is the right diameter, but the spring rate (5.6) is the same as the stock KLX250S.

 

Thanks anyway!
