Details: A large number of late-model Harley owners who prefer tall handlebars convinced us 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 site on most of Biltwell's motorcycle parts, but we think the retro hotrod styling works on this high-quality component.
Construction: Investment-cast and CNC-machined stainless steel. 5/16” x 18 t.p.i. Stainless steel bar clamp hardware.
Fitment: This one-piece riser fits rigid- and rubber-mounted top trees with 3.5” (89mm) center-to-center mounting holes only (Wide Glide, Narrow Glide, H-D aftermarket trees, etc.) If your top tree has different mounting holes, Thunder risers will not fit your motorcycle. Also, the holes on your trees must accept 1/2” O.D. hardware. The lower clamp is threaded to accept 1/2-13 mounting hardware (not included).
