The springs in my Aprilia RXV Shiver was definitaly 4,8 according to lengdth and wire diameter. What is a bit confusing is that the BMW OEM springs are exactly the same. Racetech is probably the only source that tells OEM springs to be 4,4, either we have different setup in Europe and USA or RT are wrong.
What about the shock? Is the springrate ok, or does it have to be stiffened too when upgrading the fork?
The rear shock is ok. The front was the problem. The rear seems to work a bit better now that it is not overwhelming the front froks.
That said I still plan to repalce it wtih an elka when $$ allow for it.
BTW that link is to the Factory Works forks. The Aprilia spring rates in the US are availble over on the AF1 website. They sell the replacement springs but htey are pretty expensive vs. other springs.
