The Sierra Torsion seat combines the ergonomic design and rugged serpentine spring system of a Sierra seat with our shock-isolating mechanical Torsion suspension system.

The Torsion mechanical suspension system includes an easy-turn dial to adjust the suspension for a level ride for operators weighing anywhere from 110 lbs (50 kg) to 275 lbs (125 kg). Select from the Torsion-380 or Torsion-580 shock-isolating suspensions systems, which provide 4" (102 mm) or 6" (153 mm) of ride, respectively. Adjustable lumbar support reduces back fatigue for increased rider comfort.

Customize your Sierra Torsion by selecting between a fixed or reclining back and a standard or high back. Include the optional 5" (127 mm) of manual fore/aft adjustment or armrests to further enhance rider comfort. Order your Sierra seat with a custom logo to truly make it your own.
