yfz450 front shock

They will be stiff you will one have two options with those shocks I have them one my blaster with ASR arms and I would def suggest on gettin them revaled because the two options that you are medium and stiff If you dont have the 450 stock I would spend the money and get so works just dont get really fat
 
you will have to find out what weight the 450 shocks are valved for and go from there.

yeah u can if there stock geometry mounts but most of the time it makes the shocks softer because of the more leverage but sum adjusting or a rebuild can fix that
 
Yeah but the would spend the money on works made for the length and weight then gettin your stock rebuild I think that it would be a waste of your money
