Biltwell Thunder Risers

A large number of late-model Harley owners who prefer tall handlebars convinced Biltwell to develop the Thunder risers. This riser’s one-piece design increases riser stiffness and clamping power on rubber-mounted top trees, and is a boon to performance and style on practically any motorcycle. Bold branding is an uncommon sight on most of Biltwell's motorcycle parts, however, the Thunder Risers are an exception.

  • CNC-machined stainless steel
  • 5/16” x 18 t.p.i. stainless steel bar clamp hardware
