The ST4 from Orange Bikes as been totally revamped for 2011, and is a lighter and more agile XC/trail bike when compared to the more burly Five. The shock has been repositioned and now sits beneath the top tube and the linkages have been changed to lower the leverage ratio on the shock. The 110mm travel is now achieved by using a longer stroke (190mm) custom tuned Fox RP23 shock (compared to 165mm shock stroke on the old ST4).
