Allows you to run a 108mm radial caliper on the rear when running a aftermarket aluminum swingarm.
Use a 3/8" Heim Joint to attach the bracket to your swingarm. Heim Joint not included.
For 108mm Brake Calipers
Works with your stock rotor or add spacers for oversized rotors.
Custom wheel spacers are required and not included.
Kraus Motor Company has designed and engineered the DYNAMOTO SP INVERTED FRONT END to be the absolute best performance suspension product for Harley-Davidson™ motorcycles.
The Dynamoto SP package takes all of the guesswork and hassle out of upgrading your motorcycles suspension. Suspension is extremely important and is at the core of a properly functional, fun and stable motorcycle.
Suspension works to keep traction, controls the reaction of the motorcycle to road conditions, controls brake dive and increases the overall stability. A well tuned suspension ensures comfort and fun for the rider. If you’ve ever ridden a squirrelly handling machine you know exactly what we mean when we say “suspension is critical to enjoying the ride”.
The Kraus Dynamoto SP kit can fit Harley-Davidson™ motorcycles: Dyna, FXR, Sportster and Softail models. FXRT fairings will need minor modification for fork and triple tree clearance.

Front forks on a motorcycle need to be as rigid as possible, to function as effective suspension parts. They also need to be as light as possible.
An inherent advantage of inverted forks is their weight, they're lighter than conventional front ends. A steel fork tube is the heaviest part of a traditional fork assembly. By design, inverted forks have shorter and thinner walled fork tubes. This results in less steering inertia and more responsive handling feel.
One more benefit, inverted front ends deliver better compression and rebound dampening than conventional designs. Oh and one more big benefit when you compare invented front ends against conventional front (tube & slider) ends is their strength.
Most of the stress applied to forks occurs just below the bottom triple tree. When you pull the brake lever you are “braking the wheel” and the bike slows because the front wheel is attached to the front suspension. The momentum of the bike transmits through the forks, trying to push the front wheel.
Think of the force being exerted upon a steel fork tube, just below the lower triple tree, now think of that same force on an inverted front end - clearly the inverted front end is stronger, by far, the tube absorbing those forces is of a much greater diameter.
Inverted forks are exponentially more rigid because they mount the larger diameter “slider” to the triple tree. Conventional forks mount to the triple tree via the smaller and heavier steel fork tube.
The much more rigid (compared to a steel fork tube) slider makes up a higher percentage of the overall length in an inverted front end. This design benefit reduces flex and improves handling and feel, what we call “connectedness” when compared to a conventional design..
Additionally, inverted forks are stronger because they have more overlap – the distance the fork tube protrudes into the slider – than conventional forks. The more overlap, the more rigid the front fork assembly.
Clearly, you can see why we are such fans and proponents of the inverted front fork design!! There is no reason we all can’t enjoy the benefits of a well built and designed front suspension. KRAUS is working hard to bring these big benefits to the riders that need and will appreciate them most, the Long Riding touring set and the Dyna Tough riders!
KRAUS Triple Trees are the foundation of a strong suspension. Our KRAUS Dynamoto Triple Trees are the best for the application.
KRAUS Dynamoto Triple Trees are machined from solid billet, anodized black and are designed with a proprietary geometry tweak to tighten up and improve the performance and handling of your machine. Substantial, well designed, engineered and strong these are the best triple trees for the money – anywhere.
KRAUS Dynamoto Triple Trees come complete with a steel stem, and are ready to install on your Harley-Davidson™ FXD, FXR, Softail™ or XL.
KRAUS Dynamoto Triple Trees use OEM H-D stock size neck bearings. These units come complete with a removable steering stop plate for custom frames with hidden steering stops. KRAUS Dynamoto Triple Trees have 50mm top clamps, the bottom tree has 54mm clamps.
