Does any1 know how to measure the spring rate?
I bought a spring off of ebay, and the guy said it was a 4.9kg/mm. he said it was the stock one off a 2006 RM125. It is bright red just like the stockers. But after goin through both Race Tech and MX-Tech, they both said that the stock spring rate for a '06 RM125 is 4.6kg/mm.
the guy said the shop measured it and said it was a 4.9kg/mm. so i'm wonderin if this is goin be the right spring rate for me, with is 4.9, does any1 know how i could tell if this guy knows what he was talkin about, or just blowin smoke. And does any1 know the stock spring rate for a '06 RM125?
thanks
