The Marzocchi forks used in most Victory's come from the factory with Golden Spectro 7.5wt. I had heard that Vic is now using two different fork brands in the Vision however, so that could explain the difference. Remember though, that the harsher ride is also a result of a different rear shock/spring assembly as well, as indicated by different part numbers between '11 and '09... My guess would be that changing the fork oil to a lighter weight and swapping out the rear shock for an older model would return the bike to the cushier ride that the earlier model years enjoyed.
