Thunder Riser - Black



This one-piece, investment-cast handlebar riser evolved from builder demand for a stiffer unit, and one that offers greater surface area and clamping power on tall handlebars.

Technical Details

  • Investment-cast stainless-steel construction with raised Biltwell wordmark detailing
  • One-piece bottom clamp design features threaded mounting holes on 3.5-inch centers to fit most stock and select aftermarket H-D trees
  • Large one-piece bar clamp generates more clamping power against 1-inch O.D. bars—great for apes and other tall bar styles
  • 2-inch rise from mounting base to center line of handlebar clamp
  • Polished raw or black electroplated finishes available
  • Accepts stock H-D or aftermarket 1/2-13 t.p.i. mounting hardware
  • Bar clamps feature 5/16-18 t.p.i. stainless-steel Allen cap screws

    Form and Function

    Tall apes are a great look on custom choppers, but the leverage they generate can lead to bar slip inside old or tired two-piece risers. Our Thunder riser combats this problem by adding clamping power and surface area around the handlebars. Thunder riser's one-piece design enhances stiffness in the top tree to reduce lateral twist. NOTE: If your motorcycle has removable bar clamps and its top tree accepts 1/2-inch O.D. mounting hardware, our Thunder riser should fit, but only if the mounting hole centers on your tree are 3.5 inches apart.
