Fazer 1000 nitron or hyperpro whatever rear shock ??

[PieEater]

I'm another fan of Nitron shocks, mine transformed the handling of my GEN1 coming from the OEM shock. I am inclined though to agree with NorthWestern I'm not sure that the outlay of ~£600 is going to be worth it as you already have a fairly decent replacement. Getting the R6 shock serviced and resprung if appropriate would be a good move if it's more than a couple of years old, and spend the change on getting the forks sorted or getting the bike Ivanised if you haven't already.
