Taking Best of Show at the 2017 Rider RoundUp Calendar Bike Building Championship was Max Hazan's hand crafted Supercharged KTM Single Cafe Racer. Max, who has a storefront custom bike shop in Venice Beach, CA, built this latest customer consigned bike bike from scratch around a 420cc KTM / Husqvarna 4-stroke single cylinder dirt bike engine. Max fabricated a belt drive system off the engine's crankshaft to run a mini dual rotor Supercharger fed by a Keihin FCR39 Racing Carburetor.
The KTM single's steel tube rigid frame chases hosing the water-cooled motor was built around 26-inch classic car tires with custom built spoked wheels. The tiny rear disc brake located behind the rider's right foot, operates a shaft through the frame with a fixed primary sprocket on the other side, engaged with the drive chain, to slow the rear wheel down when the foot bake is pressed. Very original! The hand made springer front forks with hydraulic damping and a front headlight that turns with the steering stem is also unique. The bike is finished off with a beautiful had made aluminum fuel tank, handlebars and many other components. It was unanimous by anyone who saw it, that Max’s Supercharged KTM Board Track Racer Replica was the Show winner, one of the Calendar Bike Building Championship’s best ever builds in its 26 year history.
