A new handlebar made the biggest difference in comfort, without affecting handling. Comparing the shiver's steel unit with the six bars on Renthal's detailed application chart, we chose a black Road Medium ($64.95, www.renthal.com). It's 1.4 nches taller overall, has 1.3 in. more initial rise, is swept back .8 in., about the same width and one pound lighter. This bar's more generous dimensions stretched the clutch cable and left-side switch assembly wires to their max, but didn't cause any problems.
