Thunderbike GT-B • Harley-Davidson Softail Breakout Custom

Raising the Curtain to Premiere

This is the first breakout with our exclusive GT sole! When we’re allowed to pull out all the stops, it’s a particularly festive act. We don’t just have GT wheels in our signature format. It’s no coincidence that we talk about size, because we’re literally always a little bit bigger. That’s why we’ve gone up a size in both front and rear. And so begins the project of our first Breakout with GT suspension.

Upward Potential for GT

With standard 21-inch front and 18-inch rear wheels, the Breakout does not roll on a small foot. However, the elongated layout of its chassis leaves plenty of room for improvement, so the Breakout GT-B now rolls on 23-inch front and 21-inch rear wheels, and 3-piece machined aluminum wheels with technoid spokes. It is as if Mother Nature, with her ice crystals, created the model for these spoke lines. And when technology challenges nature, not only is the function right, but the aesthetics as well.

Let your eyes rest on these wheels and their bolted connections, especially on the rear wheel designed for our single-sided swingarms. Singleside is what we call the swingarm kit that completely reveals the right side of the GT wheel with its sexy racing cap.

GP rear fender as the crowning glory

The Singleside package also includes the giant perimeter brake disc with internally-articulated caliper, another racing technology, a contrast-cut pulley, and our side license plate holder with Inside license plate. Yes, and the crowning glory is our GP rear fender, because in addition to GT, we also have our GP series. So this GP rear fender is seamlessly welded to the frame, with well hidden multifunctional rear lights and adapted to the 260 tires and the 260 seat shell with a Spirit Leather saddle.

Welding on the rear end is certainly the more elegant solution. But if you don’t want to go through the hassle of building a new frame, the GP rear end is also available as a bolt-on for Twin Cam and Milwaukee-Eight.

The louvered air intakes are a testament to our attention to detail. The Air Ride for the rear including Slamtail suspension with linear travel is an extra, but when we do custom, we do it right.

A clear view of the GT bike. This is possible with our Singleside Swingarm Kit and the Jekill and Hyde Shorties. GT wheel, GP rear fender, singleside swingarm kit, perimeter brake, GP pulley and side license plate holder form a powerful composition.

Diamond like Carbon

Das gilt auch für´s Frontend das stammt nämlich komplett aus unserem Haus. Natürlich ist unsere Gabel tiefergelegt, und die Standrohre sind nicht einfach geschwärzt, sondern DLC-beschichtet. „Diamond like Carbon“ – das ist die qualitativ hochwertigste Ausführung, die man einem Gabelrohr angedeihen lassen kann. Dem mächtigen Format des Vorderrades haben wir die Vegas-Bremsscheibe angepasst. Die hat nun einen Durchmesser von 340 statt 300 Millimetern, und die Bremszangen haben wir dafür auf unsere Adapter versetzt. Der Frontfender ist unser Breakout-Fender aus leichtem GFK. Den Lenker haben wir original belassen, aber auf kürzere Flat-Riser gesetzt. Die Base Rubber-Griffe liegen gut in der Hand, und die Stripe-Blinker müssen wir wie üblich erwähnen, weil sie ja sonst keiner sieht.

The same goes for the front end, which is made entirely in-house. Of course, our fork is lowered and the stanchions are not just blackened, but DLC coated. “Diamond like Carbon” is the highest quality finish that can be applied to a fork tube. We have resized the Vegas disc to match the massive size of the front wheel. It is now 340 millimeters in diameter instead of 300 millimeters, and we have moved the calipers to our adapters. The front fender is our breakout fender made of lightweight fiberglass. We kept the handlebars original, but went with shorter flat risers. The base rubber grips feel good in the hand and, as usual, we have to mention the stripe indicators because no one else can see them.

Diamond like carbon: the fork legs are DLC coated

We have bolted the original handlebars to our shorter flat risers. This means it matches our headlight cap

The Vegas brake disk has a diameter of 340 millimeters. We have made our own adapters to ensure that the caliper fits correctly

The GT-B's new face

Our GT-B shows a new face with our Headlamp cap and especially with our GP long bow spoiler. Our forward mounted V-Tech footrests make the line narrower. And let’s not forget that we added an FXDR tank this time. This has become rare. It also contributes to the GT-B’s sleeker appearance with its more angular flanks.

The blackening and powder coating of the engine components such as the rocker boxes, torque air cleaner, camshaft and primary covers are part of the visual fine-tuning. This has to be striking, but not steal the show from Ingo Kruse’s paintwork. As usual, it is not overly thick, but at second glance we find the grid grain of the air scoops in the rear fender and chin fairing.

How serious customizing works

What we don’t find is a muffler system that blocks the rear view. We used the shortys from Jekill and Hyde. So the view of the GT wheel remains clear and the sound is always sustainable, but also always legal. This is how serious customizing works, even serious can be spectacular. And with its GT wheels, our Breakout now has a real format in the literal sense of the word.
