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, 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.
Note: Performance Triple Trees are not designed for off-road use.

- Harley-Davidson® Dyna™ (90-17)
- Harley-Davidson® Sportster™ (87-03)
