Brock’s Performance has professionally designed and fabricated V-Twin Triple Trees with Reversible Bottom Clamp which will allow conversion of select Harley-Davidson® FXR™, Dyna™ and Sportster™ forks to late model upside-down (inverted) sportbike forks to take your riding to the next level. These triple clamps not only allow the use of readily available OEM forks (GSX-R1000, Hayabusa, etc...,) but also simultaneously add the ability to use corresponding wheels and brakes, increasing overall suspension performance and comfort while providing world class braking options. Featuring zero (1-1) rake and the stock 2 3/8" Dyna offset (optional 1.7” reduced trail option available), we also accommodate the stock fork stops and lock (when possible). Available in 50/54 with a 207mm spread (GSX-R1000) and 50/55 with a 214mm spread (Hayabusa). See overview and technical tabs for more info. Proudly made in the USA.

Known Fitment Applications:

  • Harley-Davidson® FXR™ (87-94) (Including CVO)
  • Harley-Davidson® Dyna™ (90-17)
  • Harley-Davidson® Sportster™ (87-03)

All remaining years of FXR™, Dyna™ and Sportster™ will accept the clamp with small modifications. The clamp will also fit custom applications utilizing a 1” DIA Harley-Davidson® steering stem. This is a bolt on application for any frame with the fork stop on the front of the neck; all other frames will require a fabricated fork stop.
