Crimson Force

customized Harley-Davidson Softail Fat Boy 114

Noble in scarlet paint!


It’s easy to spot the Crimson Force as a real Thunderbike at first glance. Its mighty wheels give it an equally mighty line, because you won’t find a 21-inch rear wheel on every custom bike. Another great example of the versatility of our Force range, the Crimson Force is a real eye-catcher with its scarlet red livery.

The Crimson Force is the next Milwaukee-Eight Fat Boy in the ‘Force’ series, with characteristic features. The core of the bike is largely unchanged. But the Kruse Design paint job makes the bike unmistakable right down the middle.

This time it’s a deep red, “Crimson”, which means “Scarlet Red” in English. We know the colour from the ink box, and weren’t we the first to draw that deep, warm red when we were little boys?

Now we find it again on a bike for big boys. Their shoe size has grown enormously. Up front we find the Big Speed five-spoke wheel, measuring 23 inches in diameter and 130 millimetres wide. That’s quite a statement.

It’s no less impressive at the rear with a 21-inch, 260mm wheel. This wheel sits in one of our single-sided swingarms that replace the standard Softail sporty. There is no hiding the perimeter brake. Erik Buell made this brake system famous on his racers.

An Air ride and the tight and bulky steel fender smooth out the rear end when standing still, when everyone looks closer.

But it is not only on the outside that we are thick. The Flip-II handlebar is also one of our strengths. It sits in strong, old-style risers that allow cables to be routed internally. The Flip II’s dominant base is expressed in all its angularity.

Clean look: the cables are routed through the inside of the Flip II handlebars

The old-style risers have a firm grip on the Flip-II

Jekill & Hyde once again promises the perfect sound. At the push of a button!

The single-sided swingarm gives a clear view of the big-speed bike


With the Force range of bikes, such as the Road Force, Red Force and Black Apple, we showcase our distinctive Thunderbike line. But it’s not just the looks that are impressive. Like the style? We can customise it for you and build your own power on two wheels.
