Started 3 years ago and still unfinished business (until it is raced) at the time of this writing, this custom motorcycle may be in Bonneville in September to prove to the world that a 1800 cc Knucklehead fitted with a customized M45 compressor can beat a land speed record. The story of this bike began during the 2007 AMD European Championship of Bike Building held in Germany. It’s where Peder Johanson from HogTech, one of the top Swedish chopper frame builders met with Paul Funk, the master motor engineer of Perfect Twin Performance in the Netherlands whio is dedicating his life to perfecting the V-Twin engine to make it 100% reliable, run much faster while almost vibrations free.
Both men clicked, sharing the same passion for drag racing, top fuelers, Indy 500 racers and 60’s and 70’s American Funny cars. After several meetings, and as you could easily predict, the vision of a new bike slowly formed in their minds. A sketch was submitted to one of Peder’s clients, another fast V-Twin freak, who immediately got involved in the project and financed it although it was impossible to set up a final budget. A third man joined into the project, Joop Van Amelsvoord another motor expert at Supercycles in Holland.
In 2008 and 2009 using CAD, 3D renderings of the gas tank, front forks and of all custom parts were produced. First, a real size drawing of the frame and girder forks was emailed to Peder, who had them print out 1:1 and started bending and welding tubes of steel. A few months later the 1800 cc Knucklehead was finished, outtake valves where raised and in general the engine was bombproof and ready for the blower. Custom made parts were fitted, everything was measured, realigned and fitted to the smallest possible tolerances. A preview of the unfinished bike was offered in June 2008 on the HogTech booth during a European bike show, and it’s when everybody started to ask the same question- ‘Will it be raced on the Bonneville Salts”? Between clients’ jobs at their respective shops, 2009 was spent fabricating, improving and completing all the most intricate custom parts like the ribbed brake plates to make them look like those of the 60’s Indy racers. Paul Funk and Peder Johanson tell me that they now feel ready for the transatlantic trip to the Salts of Utah to race their 1800 cc Knuckle Brickyard Killer. And if you wonder what their engine and compressor are “made of”, below is the list of components. (pictures Horst Roesler, Paul Funk)
