can i use an crf250r 2016 shock spring on an crf450 2018 ?
They almost look the same apart from the spring for the 250 is aprox 3/4'' longer / higher than the 450. they are not the same stiffness, so is this the reason for the different length, or is it another type ?
the red one on the picture is for the 450

Spring length does not affect ride height, geometric or any other suspension parameter. It is just a longer spring, adding some weight.
Stock spring is 247mm, but 255 and 260mm is also common from 3rd part and ok to use. You can still use the model where you drop the shock down and pull it out between swingarm and subframe on right side of bike with a 260mm spring but it just gets slightly more delicate.
It doesn't matter how long a spring is, that spring has a rate... only if you change the length of that spring (by shortening it) will the rate change.
