Why Inverted?

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”.
For full fitment you will need to add an Axle and Spacer option, a Headlight or Fairing option, a Fender option, and Rotor Spacers for 2005 and previous front wheels.
Complete with:
- Ohlins R&T forks sprung for your Harley
- Right and left 108mm Radial Caliper Adapters
- Dynamoto Triple Trees
Recommended Accessories:
- Axle and spacers for your stock Harley or aftermarket wheel
- GPR Steering Stabilizer Kit for extra stability and control
- Headlight Visor Mount to bolt on your stock Harley visor and mount your original headlight. Use our Bottom Headlight Mount to fasten your Harley or aftermarket headlight to your bottom Dynamoto Triple Tree
- FXDXT Fairing Mounts to run a T-Sport fairing with your inverted front end
- Carbon Fiber or Fiber Glass Fender Kits to keep the dirt off your face
- Run radial calipers with a Beringer Front Brake Kit
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.

Our kits bolt on to:
- Dyna
- FXR
- Sportster
- Softail

Why an Inverted front fork suspension is superior to a conventional (tube & slider) front suspension

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.

Inverted forks, by design are stronger than conventional front end assemblies

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!

49mm Sport Performance Triple Tree Set

$950.00 USD

KRAUS 49mm Triple Trees are the foundation of a strong, properly engineered front end.

KRAUS 49mm Triple Trees are engineered and designed to improve the handling and behavior of your Harley Dyna. We have applied all of the knowledge that we've gained from our Dynamoto inverted front ends to the design and geometry of these trees, offering the absolute best setup using stock 49mm forks. The 49mm trees have 0 degrees of rake and a proprietary offset that correct many of the bad handling characteristics of the late model Dynas . The larger surface area of the fork clamps and the engineered cross section offer more rigidity and strength over stock. The use of a bearing tensioning nut offers positive and secure bearing adjustment. These improvements directly affect the behavior of the front end. Making the bike feel lighter, more agile and more stable at both high and low speeds. Machined in the USA from solid billet aluminum to world class standards.

KRAUS 49mm Triple Trees come complete with a nickel coated, high strength alloy steel stem, and are ready to install on your Harley-Davidson™ Dyna or custom bike.

GPR Steering Damper ready - Add a GPR Steering Damper with a Kraus Mount for the ultimate stability and control

KRAUS Triple Trees use OEM H-D stock size neck bearings. (bearings not included)

Technical

As a motorcycle rider one thing is sure, that once you've experienced a taste of performance and ability in a motorcycle it becomes more and more important. To be sure of a machines capabilities allows the world to open up. When you know you can get on a bike and ride 500 miles in a day and there are very few other machines on the road that compare is empowering. We exist and thrive in the custom world of machines and in this work there’s one consistent thread. Always improve. With this bike I chose to build a rocketship. We are running our Kraus Dynamoto Inverted Front End with Ohlins forks and Beringer Radial Brake Calipers. This bike doesn't only handle amazing but it goes fast, and stops with extreme quickness.
I knew the Dynamite motor needed to be something special so I called on my friend Dave Bozzie to work his expertise. With the help of Feuling Parts, S&S Cycles, and Delkron Dave set out to build a high revving snappy 107”. We Took almost 4 lbs out of the flywheel, polished, welded and balanced it. Keeping the stroke stock Dave added displacement with bigger cylinders and pistons. Feuling Parts provided one of their complete Bulletproof Geardrive Cam Chest kits, Beehive Valve springs and Titanium Keepers. The Heads had about a weeks worth of work in them. All the magic tricks! The motor revs to 8000rpm with a very smooth climbing torque curve. There’s a power band hit at 4,100 RPM than pulls your neck back. The motor was built to compliment the handling and overall geometry of this Dyna. The Carbon Fiber BST wheels make a huge difference with spin up and braking. They really make the bike feel and act very light. We machined a one off Billet Trellised swing arm out of 7075 aluminum that sits at a steeper angle and adds about 2 inches of height in the back of the bike. This increase gives a lot of ground clearance and steepens the neck angle to improve agility and corner ability. The fully adjustable Ohlins shocks suck up bumps and stabilize the rear end of this beast nicely. Of course up front we are running our Kraus Dynamoto Inverted Front End with Ohlins forks and Beringer Radial Brake Calipers. This bike doesn't only handle amazing but it goes fast, and stops with extreme quickness. I’ve done some big road trips on this bike already, usually making sure to find the windiest roads to travel on. It handles the big open highways like a big bike should but also pitches into the corners with ease and confidence. It tracks very well, I have not found any ill handling issues. The bike is tight and crisp and does not have any of the sloppy feeling of a harley. As far as I’m concerned the bike does everything it was intended to do with flying colors. Total success!
