I fit a lot of
Hyperpro progressive fork springs to SV's, more than any other product. They are dead easy to fit, remove the fork (loosen the fork tops before undoing the yoke clamp bolts), remove the internals, pump the oil out, replace internals with new spring, top up the oil (weight specific) and bolt the fork back in the bike. Job done, nice and easy!
I
wouldn't recommend the
full Hyperpro kit which comes with a replacement rear shock spring, its not the spring that is the problem with the OEM SV shock, its the actual shock itself!
