just replaced the rear shock on the 13, and had the forks revalved and re sprung, the shock was a shock factory shock with stiffer spring, the forks have had stiffer springs and a revalve done by a company called shock tech here in the UK. must say so far i am impressed, the bike just seems a lot firmer but still compliant, got a five week trip starting on the 13th of this month, i will be two up and fully loaded so that should give it a good workout, will post back with thoughts.
