Biltwell Thunder Risers

Investment-cast and CNC-machined stainless steel. 5/16" x 18 t.p.i. Stainless steel bar clamp hardware.

This one-piece riser fits rigid- and rubber-mounted top trees with 3.5" (89mm) center-to-center mounting holes only. 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)
