The custom BMW R 18 B ‘Heavy Duty,’ designed by Fred Kodlin and his son Len, was unveiled at this year’s Daytona Bike Week. The bike features modifications to the frame, the addition of an air suspension system, a custom paint job by tattoo artist Marcel Sinnwell, and adaptations to the body that serve both for function and, in the case of the winglets, strictly for the sake of form. For more information, read the press release from BMW Motorrad below.
Anyone who talks about the U.S. customizing scene mentions Fred Kodlin almost in the same breath. For more than 40 years, he has dedicated himself to customizing motorbikes, from radically modified creations to sophisticated new designs. Since the 1990s, he has been incredibly successful with his custom bikes and was able to win various important Daytona shows regularly. He was the very first non-U.S. citizen to be inducted into the Sturgis Hall of Fame.
For the first time, Kodlin has now set about customizing a BMW together with his son Len: the BMW R 18 B. “The R 18 B Heavy Duty was a real father-son project,” said the boss of Kodlin Bikes in Borken, Germany, happily. “There was a lot of creative input from Len, which also goes to show that the next generation at Kodlin Bikes is already in the starting blocks.”

Massive BMW R 18 B Chassis Technology Adaptations
The biggest challenge in customizing this year’s crowd puller at the Daytona Bike Week in Florida was undoubtedly the frame. “We have completely remanufactured the upper tubes to lower the fly-line and thus the seat height of the R 18 B,” explained Fred Kodlin. “We also redid the steering head and the triple clamps so that the caster fits despite the changed steering angle and so that the bike rides well.”
The result was the R 18 B Heavy Duty, a bike in typical Kodlin style. Viewed from the side, the fly-line drops sharply to the rear from the chopped windshield taken from the Original BMW Motorrad Accessories range and finally runs harmoniously into the side cases made by Kodlin out of glass fibre-reinforced plastic and the low rear end. From the top, the R 18 B Heavy Duty is characterized by a strong waistline in the seat area and a flowing connection to the side cases.
Finally, the technical chassis highlight is an air suspension system at the front and rear, supported by a compressor placed barely visibly behind the left side case. This allows the R 18 B Heavy Duty to be lowered and raised in a fraction of a second. This is both as useful as it is spectacular: To park, lower the chassis, and it rests on hidden support points letting the bike crouch just a few centimeters above the asphalt, waiting for the next ride.

Extensive BMW R 18 Body Modifications
The Kodlin team also delved deeply into the subject of body construction for a good three months. A completely new sheet metal tank was created – longer than the original, flowing in shape and with indentations on the sides. The connection of the tank and rear frame was also modified for this purpose. The original mobile phone charging compartment, on the other hand, has been taken over from the R 18 B.
A front spoiler, including a three-color underfloor lighting system – a popular feature, not only in Daytona – and a front fender are also made of sheet metal, the fender fitting snugly around the 21-inch front wheel. Finally, Kodlin created a corresponding counterpart for the rear wheel from two R 18 B rear fenders joined together, in which the rear and side indicator lights are integrated in a very discreet manner.
The two side covers made of sheet metal, which form a smooth transition to the side cases, are completely custom-made. Speaking of side cases, R 18 B loudspeakers by Marshall and an amplifier are fitted inside. Kodlin’s attention to detail is also evident in the aluminum milled hinge panels of the cases in the style of the original R 18 B components.
The so-called winglets above the cylinders are another design element. They are also made of metal but do not fulfil any function in the actual sense. Rather, they underline the design of the R 18 B Heavy Duty and make it appear unmistakable, especially when viewed from the front. The customizing job is rounded off by a seat made by Kodlin and an instrument cover with covers made of Alcantara and imitation leather, as well as specially made handlebars and a self-created exhaust system.

Elaborate Paintwork by Tattoo Artist Marcel Sinnwell
Marcel Sinnwell has painted other Kodlin showbikes in the past, but these days, he only rarely picks up a spray gun for very special jobs. For example, when he paints yachts or an R 18 B Heavy Duty.
For this project, the color gradients were completely airbrushed with translucent paint. The inspiration for this was the mixing of color pigments in the paint and especially the way form streaks in the milky basecoat when first stirred. The result goes along very well with Daytona Bike Week, where complex and colorful paint schemes are more than just good form.
Additional design touches on the R 18 B Heavy Duty are provided by hand-painted pinstripes and an airbrushed pattern on the rear fender that combines Kodlin and “100 years of BMW Motorrad.” The brake calipers, gearshift, and foot brake levers and footrests, however, are BMW Motorrad standard components that have been color-matched.
BMW R 18 B: The Perfect Bike for Customizing
But Fred Kodlin by no means laid his hands on all the assemblies and parts. He said what was a particularly positive surprise for him was the bolts. “They are all made of stainless steel, with a nice Torx head,” he said. “That’s not the way it is on other bikes. The basic bike and especially the engine are very, very cleanly finished. All the electrical cables are already nicely hidden, so we didn’t have to do anything to the engine.”

For this reason, numerous R 18 B components were deliberately not replaced but at most modified. For example, the shortened hand levers and handlebar end weights. Likewise, the engine remained unchanged from a technical point of view. Only the cylinder head covers, belt cover, and intake snorkel were painted in metallic black.
Cruise control with distance control, reverse gear, and eCall have remained unchanged. These are absolutely unique features of the BMW R 18 B in the cruiser world, where these functions are not offered by any other manufacturer.
The Custom BMW R 18 B Heavy Duty is an impressive bike that made its debut at Daytona Bike Week. Its rugged, all-black design and impressive power make it a standout among custom motorcycles. The bike features a host of modifications, including a new exhaust system and custom seat. Overall, the Heavy Duty is an impressive machine that showcases the potential of the BMW R 18 B.
